Box Joint Cauls

Make perfect joints with our Box Joint Jig and NEW Cauls!

Description of the Box Joint Cauls

Uniformly spaced pressure points clamp individual box joint fingers at the corners to give you the tightest joints possible. Simply align the pressure points with box joint fingers and tighten in place with one or more Rockler 1'' x 15' Band Clamp. Slots on the outside of the cauls are made to hold pennies firmly in place to support your Band Clamps at varying heights. Plastic cauls stand 6-1/4" (1/4" Cauls), 6-3/8" (3/8" Cauls), 6-1/2" (1/2" Cauls) and 8-1/4" (3/4" Cauls) tall.
