One of the elements of theater magic is rolling scenery. The scenery, which is on casters, needs to be quickly and safely moved on and off stage with precise timing. The Rosco Wagon Brake with Extension Spindle (5/16 x 2 1/2") makes this possible. Fitted to the side of a platform or scenic panel, the brake uses a lever-like action to lift the piece slightly off the floor and its casters preventing movement. Two brakes are recommended per scenic piece.
