Dry assembly of a carcass or even trying to hold two panels together to place a fixing screw often leads to much cussing and the desire for a third or even fourth hand. Right-Angle assembly clamps are that third and fourth hand, made from glass fibre reinforced nylon they have a single handed ratchet mechanism allowing them to be squeezed together across a corner, providing a firm hold. The clamps hold boards or panels from 10mm to 20mm thick at 90°, with a variation of up to 6mm in thickness between the panels. Use for test fitting, holding whilst applying cramps or placing a fixing. Overall size 100 x 75 x 40mm, sold in pairs.
