    Awesome tool!
    The CamJam® SlideLock® Rope Tightener - Large is a very useful tool. From tarps to truck bed anchor rings, this thing gets a lot of use. The size small is perfect for hoisting the electric motor on my kayak.

    Needed this size for the 6mm rope I'm securing. Seems to hold extremely well, but the test will be putting it in use with my kayak. This version also seems more secure than the Nite Ize CamJam XT, which doesn't entirely capture the rope.

    Love this Gadget!
    The CamJam SlideLock is such a great item that helps you to tighten ropes with tying items down. This is something I struggle with, and this product works perfectly. Simply put the rope into the opening and pull to tighten and lift the lever when you want to release it. It has a 500 pound working load limit. I have a big yard and take yard waste, especially branches, to the dump to dispose of, and this handy little gadget is going to make tying them all down so much easier. I’m going to buy more.

    Holds onto its advertised claims
    This is a very good tool. I often use carbineers for clipping items together or onto other objects. I have routinely tied lines and ropes to the carbineers with good success. I noted this clip allowed for a simple threading of the line through a Cam Lock to retain the line. This would enable quick changes in line length. The manufacturer notes lines from 3 to 9 millimeter (one tenth to one third inch) and still it will hold up to 1500 lbs. Well, I have a 3 mm line, but I didn’t want to lift 1500 lbs. with it. So, I did try about 50 lbs. in a small case. The line held in the Cam Lock and the case was suspended with a problem. I particularly like the slip lock on the clip, preventing it from being depressed without moving the lock Definitely, this is a great addition to my toolbox. In fact, I need a couple more.

    The hook with 1000 uses.
    Picked up one unit to play with but am already looking to buy a few more. Really wish these were around during my camping and outdoor days as they'd be awesome for hanging tarps, tents, gear and just about anything ese. The hook is slim but still large enough that it can hook around more items than most carabiners. I can't see ever hanging more than 50lbs but each hook has a 1500 break strength rating. I've currently got it rigged up with a stainless carabiner and 3ft of 3/8" braided polycord so I can move it around between a couple uses.

    Good multi purpose rope lock
    This cam style rope lock can be used in a variety of ways. My primary use is to connect myself to a safety rope so that I can work my way down a steep slope and clean out a culvert that collects leaves and sticks. While I wouldn't trust my system on a slope that I couldn't navigate without a rope it works fine here where I just need a little help. The more common use is to secure loads in my truck. It is a LOT easier to tighten and loosen the ropes securing a load with this than by tying and untying ropes. This cam lock is sturdy and is easy to move either way on a rope. It has a safety lock on the big clip to prevent accidental release.

    Easy To Use and Strong
    I wanted a clothesline that I could put up and take down easily because I didn’t want to have one permanently stretched across my yard. I like to dry multiple loads at once which can initially be quite heavy, so I had to have something that could take the load. Enter this CamJam! I bought a fifty foot length of 3/16 in. Diamond Braided Polypropylene Rope, which is roughly 5mm. I’m able to connect one end of the rope, with a carabiner and eye-bolt, to one end and the CamJam on the other end. Once connected I can tighten the line by pulling the slack through this device and it hasn’t slipped yet. It lists 3-9mm s the compatible rope diameters, but at most hardware stores, including Home Depot, it’s difficult to find 9mm rope if you were wanting to take advantage of this units maximum capability. This is in no way reflective of the quality of the device, but you should be aware that the next size up from what I’m using is 3/8, which is 9.5mm. It would probably work, but I like to stay within manufacturers specs and so opted for the 3/16. The clip on the opening has a little slide lock to help prevent accidentally opening the gate. Overall this thing seems quite sturdy and well made. The release is very easy to operate even under heavy tension. I could definitely see using this for other uses like securing a load for transport and also for easily setting up a ridge line for hanging a tarp over a hammock for camping.

    Great addition to any EDC bag
    This NiteIze carabiner is a great way to pull a ridge line for camping and holding up a tarp or anything that is needed to be used for cinching. I have used with para cord and used to hold up my EDC (every day carry) bag in the garage. I see this also a great addition to my EDC bag for extra support for many jobs and needs. Great addition to the truck for tying down loads. This indicates it is good for 3mm to 9mm rope or cord.

    I Have to Buy More! Easy to Use, Tighten and Release!
    Love this simple tool. You need a loop to hook it around so if you have the metal 2" bars it doesn't work very well. I wanted this so it would be a lot more simple for tying down stuff. Once I figured out the loop issue, it worked fabulously. It's strong and sturdy. I wanted to test it's strength and I was tugging on this big time. I wanted to see if it would hold up to the abuse it's going to get. It did. I highly recommend this rope tightener. I will have to buy more. It's easy to use, easy to release, easy to tighten. Every truck and trailer needs these! I don't see how you could break it after the abuse I put it through.

    Easy to use for securing a variety of objects
    Great addition to tool boxes, camping gear, and DIY equipment. The hook is wide and long that allows for easy attachment to various mounting points. The load rating surpasses most cords that would fit this type of application. Cords can be 1/8 inch to 3/8 inch in diameter. Installation of the cord is very easy and the cinching mechanism secures the cord strongly. The hook has a positive locking mechanism that is easy to engage and disengage.
