Gail, I just purchased a pair and set them up. To open each unit, you press on a polished button near send bolts on the affected side. This allows you to pull one pair of legs out of the top, and in turn pull them apart and push the folding strap to lock that pair. The feet swivel back and forth (not around), and self adjust. Then you do the same thing for the other side - and you're set. To pack it up, i would put it on it's back, release the bracing strap by pushing it up, first fold that pair of legs together, and then push them into the top. Repeat. Very, very easy. Very, very stable - for example, they won't willy nilly fall out while you are moving them around!
Multiple ways to answer. Side to side, yes as both surfaces are sturdy - though a lot of force would push the metal sides in. Top to bottom, the answer would be a yes, as long as the bottom of the clamp either touched both sides at the bottom as a traditional wooden woodworker's clamp could do with a wide enough throat. With something like IRWIN Quick Clamps, to some degree you could as long as an angle wasn't created which would push or pull out the metal side wall. I saw these for the first time tonight - keep that in mind - but the idea is to either put a pair of 2x4, 2x6, 2x8 and so on in the slots on either end and clamp to those - or better yet lay a sheet of plywood or MDF over the top, screw it into the said timbers and clamp your heart away. But you could do a lot of variants of these ideas. In my case I'm going to engineer a steel top on something as thin and strong as possible like engineered plywood, and have it cross braced. This may or may-not be glued, screwed or bolted to a 2x?. Hope that is helpful.
Interesting question, as I don't see that as the intent of the design. Yes, you can stack them when they are folded - but unfolded the top bar of the first unit would run into the folding brace bar/strap that stabilizes each pair of legs, thereby rending them unstackable in the traditional sense.
Fully open, they measure 28.8-inches from floor to top of beam. They are 4.7-inches tall when closed. Their width is 41.5 inches open or closed, and for completeness - they are always 2.6 inches wide (4.0 inch outer diameter from the bolt heads which stick out).
Factory spec is 13.34 lb., which I just confirmed on our scale (my weight with - my weigth without).
Just a bit shy of 29 inches.
34.6 inches outer diameter - outside of one leg to outside of the other leg, and 31.0" inner diameter. The legs are 1.5" wide each. They run perfectly parallel top to bottom when open, so these measurements are the same at any point along the height.
No, just slots for timber on the side and a very well made anti-slip treatment to the top (like spray-on grit embedded in paint).
This particular Toughbuilt Sawhorse is not adjustable. The product page on the Home Depot website lists the height as 29.5". I really like these sawhorses and for me the 29.5" is a very usable work height. The ToughBuilt 32" available at Home Depot is adjustable and has a slightly higher load capacity.
JM, I wonder if perhaps they made changes, because I just bought a pair and the picture looks just like their website, which looks just like the pair in my garage!
