Lockwood 2657 Surface Mounted Door Closer
Designed and manufactured to exacting standards. These world recognised standards ensure the highest possible quality, efficiency and reliable performance. All models (except hold-open) are tested and approved on fire doors in accordance with Australian Standard AS1905:1:2005 Fire Resistant Doorsets. New multi functional designs offer the specifier, stockist or the installer outstanding versatility and low inventory levels. Effective door installation requires that the door and frame be of sufficient strength or reinforced to ensure secure anchorage of the door closer unit. A door fitted with a door closer must be hung on good quality, aligned hinges so it swings freely without bias in both directions. The closed door must be clear in the door frame and when a lock is fitted the latch bolt must engage freely within the strike. When specifying manually operated door closers the following should be considered: door size, in particular width of door; door weight; type of installation; environmental conditions; location of door; operation frequency of door; the people using the door. Door size and the pressure exerted on the surface area of the door due to wind gusts or air conditioning and the spring strength required to hold or close the door against this pressure must be considered along with the ability of the user to exert the force necessary to push or pull the door open. The location of door furniture will influence the leverage available to the person opening the door.
