Overview
This corner clamp comes in at 8 by 6 by 0.71 inches and 1.45 kilograms, filed under Tools, Clamps. Buyer activity is the strongest in this batch, with about 300 units purchased in the past month and a 4.4 star average across 138 reviews.
The model name MY-Corner Clamp-4a and the listed dimensions point to a right angle or corner clamp used to hold two workpieces square while gluing, welding, or fastening. The flat profile at 0.71 inches thick is consistent with a clamp body rather than a bulkier bar clamp. No jaw opening or clamping force is listed, so maximum stock thickness is not confirmed.
