Overview
A workshop bench with small glue-ups and fixtures is where this resin clamp is useful. The body is black resin, which makes it light, and the item name gives its capacity.
A resin body and low weight make it easy to handle and to leave on a project. The set name mentions locking C-clamps, which is not how the product is described elsewhere, and no force figure is given.
Who it's for
Light fixturing for crafts, small frames and quick assemblies matches a resin clamp. Welding and heavy machining call for a metal clamp with a stated load rating.
Pros and cons
- Light resin body
- Easy to carry
- Limited lifetime warranty
- Clamping force not stated
- Throat depth not listed
- Resin is less rigid than steel
- Set name is confusing
Performance notes
Clamping force depends on how the jaws are closed and on the strength of the resin frame, which flexes more than metal. The listing gives no force rating. A light body is easy to position on small work.
