Why it holds
- Thickened malleable iron casting — a dense body that stays stable under load
- Rigid clamping, no slip — holds the joint square while the glue cures
- Thickened screw, hard and wear resistant — hand crank with smooth travel along the thread
- High-tension spring — quick to set and to release
- One clamp, many uses — panel glue-ups, furniture assembly, site work and stone splicing
Where it is used

Packing
Clamps are packed in export cartons. Carton quantity, net weight, gross weight and carton dimensions are confirmed with the quotation, because they depend on the size mix in your order.
