O'SKOOL Miter Max Corner Clamp for Woodworking, Making Window Casing, Making Door Casing, Crafting Projects

terrible product. i bought 2 of these to clamp architrave mitres, only got through 2 sets of arcs before one of the clamps broke. don’t waste your money

Works perfect

Wow très satisfait

I purchased this clamp because the spring clamps I used did not pull the joints tight enough. So far I've used the clamp on test cuts only, mimicking door/window casing. It works well, pulling the miter tight along the entire joint. I used minimal amounts of glue and no reinforcing, such as biscuits. The joint was very strong. A very minor amount of finessing is needed to make the miter joint perfect and the small dimples the clamp makes are a small tradeoff for the strength this clamp provides.The original Chesnut Tool Clam Clamp made in the USA was unavailable and backlogged, so I went with this one. I can't speak to durability over the long haul, but the clamp appears to be well made is a good value. I recommend it.

This clamp is top quality and works extremely well. Highly recommend for framing work like architraves etc. It is bigger and sturdier than I expected, may not be suitable for more intricate work like small picture frames.

Makes life easy while clamping and nailing woodwork

Bought two different brands at comparable prices off Amazon. Oskool significantly better made. Overall more heavy duty on almost all if not all components. Oskool cam system moves grab arm approximately 30% farther. Oskool grab screws have been machined to a sharpened edge facilitating much easier fastening with no slippage. See attached pictures. Had to tap other brand with mallet to get the screws to bite and even then experienced slippage.
