Constructed of high-density polyethylene, the Construction Caddy II is water resistant and durable. It has a big work area – 18-3/4" x 9-3/8" – that holds a piece of foam board or the Pitsco Perf Insert. Tape a template to the foam board and pin the pieces for convenient gluing. The foam board can be removed and stored, so the caddy can be used again quickly. The caddy holds pins, balsa wood sticks, glue, and more. Includes one piece of foam board. Balsa wood, glue, T-pins, Perf Insert, and Accu-Fixtures sold separately.
