Void Cap/Board Cap - 1/2” x10'– BC500

Preco Void/Board Cap is used to create a clean, professional groove over expansion board. The lower section of this polystyrene cap is placed over the top of the expansion board before the placement of concrete. Later, the top section is removed to create a smooth, “notched” reservoir for sealants. Our unique J-Hook Design ensures that the bottom half of the cap will not pull out of the concrete upon separation from the removable top portion. A single J-Hook configuration allows for placement close to existing structure. The addition of a Grip-Rite Rib allows the cap to ‘snap’ into place on the expansion board itself.
