Door Closers
Description:
Door closer is a mechanical device for closing a door after it being automatically or manually opened. Choosing a door closer should involve the consideration of a variety of criteria. Besides the door closer performance in the fire emergency, other criteria include the resistance to opening forces (for disabled or infirm use), health, safety, durability, risk of ligature and aesthetics. The key part of the door closers’ design is how to control the closing process and make sure the function parameters can be adjusted during the closing cycle.
Door closers can not only close the door but also protect the door and frame from damaging. They become increasingly vital in the modern architecture. Door closers are mainly used in the commercial, residential and public buildings. Lanteky Technology provides door closers with optimized size for use with panic exit devices.
