A manual door closer stores the energy used in the opening of the door in a compression or torsion spring and releases it to close the door. Some closers allow for adjustment of the strength of the spring, making it easier or more difficult to push the door open.
The 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! Learn More$72.79
