Kant-Slam is excellent for any self-closing door requirement. It can be used on virtually any type of fencing material for residential, commercial or secured access applications. The Kant-Slam also meets self-closing swimming pool enclosure requirements. A special feature found only in the Kant-Slam is that the closing pressure is self-contained within the unit and is transmitted through components of the closer to the mounting bracket on the frame. The result is no more pressure on the gate or door than from closing by hand. Constructed from steel, brass, teflon and oil resistant neoprene packing, Kant-Slam gives you a long lasting quality product.
