Answer: 
The top handhold is adjustable and the sander can be laid flat, but you would need to clamp it to your bench if you were running large pieces over it.

Not that I'm aware of. The way the dust bag attaches it would be difficult to use the sander inverted.

Answer: 
Not a factory made stand that I know of but if I were inclined to do something like that I would look on YouTube for some ideas on how to make one as there are plenty of people out there that have done just that. I do know that the switch has a button to lock it in the on position.

Answer: 
Yes. My sister bought my belt sander for me and it was no problem. She lives in PA and I live in HI and even though she purchased it online in PA and shipped it to me they honored the service contract. You may have to physically send in the paper work but I was able to register it and meet warranty requirements online.

Regarding Ridgid Model #R2720 Belt Sander: Will this tool connect with Ridgid wet/dry vac tubes of 1 7/8" diameter? Specifically, Ridgid # WD4522

Answer: 
Ridgid has vacuum hose adapters for various size hoses and connections and I just tried it on mine and although the fit was close it wasnt tight. The only solution I can think of is to go to the plumbing section and see if they have a 1 inch to 1 inch rubber coupling with a hose clamp on each end. I believe that would work.

Answer: 
The R2720 dust port where the dust bag connects has a 1-3/8” outer diameter size, which is smaller than the 1-7/8” size of the wet/dry vac tubes indicated. The customer might could find some type of reducer at a vac-supply center to connect the two. However, we have no information on the WD4522 to advise of with it, since we do not make or support it.

Customer Reviews

3 in. x 21 in. Heavy-Duty Belt Sander is rated 4.0 out of 5 by 54.
Rated 4 out of 5 by from Very good sander I was hesitant to buy this sander based on some of the negative reviews this sander had but I am very glad I did. The machine performs very well and the price isn't so bad for what you get. Belts are very easy to install, I had no problems with tracking and only occasionally did I need to adjust them. 4-5 adjustments in a five hour run isn't bad. I am not sure why some people were reporting that this machine eats belts as I did not experience this during 5 hours of continuous use. I bought a 5 pack of bi-directional belts for $8 and went through two and half. None of them broke they just didn't sand as effectively after awhile so I changed them out. Sandpaper does that. I wonder if the people having belt problems were using cheap belts or maybe belts that are not bi-directional? If you don't use bi-directional belts you could end up putting belts on the wrong way and perhaps then you would encounter a belt eating problem. But that would be operator error not a machine problem. The sander is easy to use, the weight is just right and I was able to sand in any direction without tracking problems. Another common problem reported was with the collection bag. Like many others I encountered this problem right after I emptied the bag for the first time. The trick is not to fill up the bag 100%. The instructions recommend to fill it half way. Well I didn't take that advice either but when it got blocked I was able to clear it with a can of compressed air like the ones you use on your computer. Just insert the straw right above the top of the sanding belt where the impellers are, spray some air and the blockage will clear and you are back in business. Lastly, is the way the sander starts up. While I would like a way to override this feature it wasn't that bad. I could see this as a benefit on some projects but it wasn't necessary for my project. It still ramps up pretty quick and the delay isn't as long as some people indicated. The reason I give it a 5 star is because of my desire to have an override on the delay start and because I think the machine should be able to clear the blockage I made on its own. But again, I was the one who insisted on maxing out the bag everytime and this will push dust back into the unit. Operator choice on this one.

Rated 5 out of 5 by from Belt sander This is a real nice belt sander and the price was great. A popular magazine reviewed some belt sanders and said that the only thing stopping this one from getting a five star rating was not having variable speed. Well these new ones do. I first tried it out on an old chopping block that was probably as old as I am and was coming apart due to glue failure. I was able to pry all the pieces apart without damaging the wood but the dried up glue needed to be removed and I was amazed at how easily this new belt sander got down to fresh wood. I have bought a number of Ridgid brand tools over the years and I think I'm going to be as happy with this new belt sander as I am with my other Ridgid tools.

Rated 1 out of 5 by from Big disappointment I've been a woodworker and worked in the trades for well over 30 years. In that time I’ve used a LOT of Ridgid tools. When it came time to replace my trusty Craftsman belt sander (bearings were shot) I did my usual online research and heard glowing reviews about the R2720. It's got the "soft start” feature, and a light in the power cord to indicate the presence of power, a Velcro strap to cinch up the cord- all of which I could give a hoot about. Actually the “soft start” feature is more of a nuisance than a benefit; having to wait on it to ramp up to speed every time you pull the trigger. I DO like the variable speed however, and also the lever which makes belt removal a snap- both nice features. Be forewarned however, that in the areas that REALLY MATTER, this belt sander falls flat on its face. First off, this thing throws out a cloud of dust like there's no tomorrow! I can sand all day with my 20+ year old Craftsman and throw off less dust and this Ridgid R2720 does in 30 seconds. I'm not exaggerating! Whoever designed this “dust collection” system should have studied at what’s out there already. One would expect a newly designed piece of equipment to exceed it’s predecessors in areas of performance. This is a MAJOR step backwards. Secondly and perhaps most importantly, out-of-the-box this belt sander couldn't sand flat. If you really want to evaluate how a belt sander sands, use it in a side to side and circular or figure-8 motion (in addition to the standard back and forth motion). All these techniques should produce a flat and smooth result with no discernable "tracks" left in the wood. The “tracks” are caused by an uneven skid plate that is not applying even support over the entire sanding footprint of the belt. If there’s a high spot on the skid plate, it will push harder on the backside of the belt and therefore sand deeper at that spot. I literally spent hours removing, flattening, reshaping and adjusting the contour of the skid plate, and even went as far as fabricating and installing a flat support bar to go across the front edge of the plate (at the mounting screws) to hold it more flat. All of my efforts finally yielded what I would consider “acceptable” results, but nothing to write home about. I eventually put new bearings in the old Craftsman and now this new Ridgid “dust machine” sits idle in my tool cabinet. If someone had published a more thorough and honest review of this tool I certainly would have steered clear and explored other options. If there was such a thing as a zero overall rating, that's what this belt sander deserves.

Rated 5 out of 5 by from Good item! This was a replacement for a spent belt sander I had. Shopped around and the deal is good. This is one heavy duty sander and if you want a really good belt sander, you found it. Powerful and easy to adjust, use and switch belts. Nice small front wheel allows close quarter sanding. Only drawbacks: The lock-on button is really hard to use for adult sized fingers. It works but is a pain to press in. Second drawback is that soft start-up. Annoying. Press the trigger and it s-l-o-w-l-y starts up to full throttle. Would be sweet if that could be disabled somehow. Pros: Much quieter than other sanders (think executive jet engine instead of tree stump grinder), heavy, does a great job for stock removal, as well as fine sanding. Nice long extension cord which is a huge plus for overhead cord pullies. Easy to switch belts without carving up your fingers and knuckles trying to operate the release. Yeah, get this. It's worth it.

Rated 4 out of 5 by from Mostly good I purchased this sander while I wait for parts to fix my beloved Bosch 1274 DVS, (discontinued, why?). I live in Hawaii and was not able to purchase this product even online. I had to get my sister to purchase it for me online in PA. Even my cousin in CA couldn't purchase this sander but I like the specs and it has a lifetime service contract that they will honor here in Hawaii, but you must purchase the sander through the Home Depot. I've been remodeling homes for 25 years and I can tell you this is the most powerful and smoothest 3x21 belt sander I've ever used, I really like it. Now here are the negatives. 1. I just completed my first project with it, a set of stairs. All the wood had to be milled and sanded so it was a fair amount of work but my Bosch did half the work before the toothed sprocket wore out. Now I already I have to replace the timing belt (drive belt) on this sander. I can't believe it wore out so quickly, I hope this isn't a constant problem with the tool. 2. I thought the top of the sander was flat so that I could use it upside down on my workbench, but it is slightly domed, so close to a perfect design but no, fail. 3. The dust collection is great when it's hooked up to my shop vac but without a vacuum, the air vent for the motor blows right in your face. I guess engineers do their best to think of everything before production but they blew it, so to speak, on this one. Now it's in production and I guess it's too expensive to do a redesign so soon. Maybe that's why it's so cheap. It's obviously a heavy duty sander and I suspect it will last me for the rest of my life.

Rated 1 out of 5 by from Belt Buster Champion I purchased this sander to remove the finish from a large deck. I was disappointed to find that unlike Ridgid orbital sanders, it did not include an adapter for a shop vac. In addition, the sander is quite long and heavy, so it is really only suitable for large horizontal surfaces. But the really unacceptable feature is that it tracks poorly and destroys belts after a short period of time. Cons: 1. After about 3 hours of use, the sander started eating belts. The belts tracked ok, but they failed after running for several minutes. My older sander ran belts from the same package fine. 2. No vac. adapter. 3. The length is unwieldy. Pros: 1. The motor worked OK. 2. Variable speed is convenient. 3. Easy belt installation. You will take advantage of this because you will install many.

Rated 5 out of 5 by from one of the better This belt sander is one of the finest I've used. It has excellent dust collection for a belt sander. It actually picks up about a half or more of the dust which is unheard of. It has plenty of power and weight is excellently centered. Theres a couple porter cable and makita belt sanders at work but I believe this one takes the cake. I might have to buy another just for work. But it is heavy and thats not a bad thing for the people that dont know this the more weight it has the least force you have to apply which is great because you can move the sander around easier. I build cabinets profesionaly and i appove this for my shop. For the people that used it on decks a belt sander is used to make one surface flush to another, deck boards are warped that is not the tool for the job. The only problem i have with this is the soft start which takes to much time to start up. But other than that its a winner

Rated 5 out of 5 by from Pretty Good Sander I purchased this sander about one year ago and have not had a problem with it yet. The dust bag collects a large amount of dust and it also has a precise change in speed so its great for every type of wood even hard wood. You can also change the belts pretty quickly too. The sander is a little expensive but with a lifetime warranty it also unbeatable.
