Media cannot be loaded. I took some scrap wood and made 45 degree cuts to make a test photo frame using a kotto strap clip. Result and ease of use of the clamp. Watch our attached video of how we use the clamp. Pros: -- The resulting test frame I took was perfectly square with the opposite diagonal measurements being exactly the same. -- Nylon straps did not slip at all after locking when the strap was tight. -- The handle has a good grip and is wide enough to get good torque on the belt. - Each of the corners has a relief cut that allows you to see the gusset and make small adjustments with the strap to ensure a perfect connection before final clamping. -- Corners relative to wood are flat, without texture, so they don't damage the wood. - PRICE: only $20. very bad: -- All parts except the screw are made of plastic. It probably won't stand up to constant use, but it's great for the hobby home carpenter. -- Be careful to remove the adhesive from the tape as the cured adhesive on the tape will not allow the tape to pass through the narrow slots.
