This clapboard is used in film productions, TV commercials, video productions and has flat black sticks and boards with a deep black non-reflective surface, ideal for brightly lit situations. It measures 11" x 12" and is made from a durable, tempered hardboard with a special chalkboard surface. The sticks are made from select northern hardwoods, hinged by rigid steel plates and rivets to insure continued, rigorous use by professionals. Professional Clapper Board Quality: Many of the novelty clappers, that look similar to this model, are made using inferior materials and craftsmanship. Luan wood is used for the board which breaks, warps and cracks easily, the finish is slick painted making it hard to write using chalk and are held in place by tacks rather than the steel rivets and plates.
