Back checks: Application areas
Back checks for entrance doors
Wind or draft may pull doors away from the hand and hit against the facade, the wall or, in worst-case scenario, someone that passes by. Back checks help prevent damages such as torn out hinges or broken overhead door closers, along with personal injury.
Back checks for industrial buildings
Problems also often arise with exterior doors in industrial buildings. If these slam open due to the wind, it can pose a safety hazard. Back checks ensure safety by slowing down the door as soon as the speed of the door becomes too quick.
Back checks for public buildings
Highly frequented doors in public buildings (town halls, trade fairs, public toilets, etc.) can often open too far due to careless operation. Back checks are the perfect
alternative to door stops here, as they do not pose a tripping hazard. They also protect the door and its hardware.
Back checks for schools & daycare centers
Doors in schools and daycare facilities are often exposed to the rush of children who want to leave the building as fast as possible. Back check prevent an uncontrolled opening and damage to the door, together with possible injuries to the students and teachers.
Back checks for shops
Shops often have large glass entrance doors. These heavy doors can quickly become a danger to passers-by if the speed becomes too high due to wind, draft or careless operation.
Back checks for windows
Especially in buildings where windows are operated frequently, wind, draft and carelessness may lead to damages, which often result in high repair costs. Back checks are also the ideal solution in this case, and can also be easily installed on tilt and turn windows.
Back checks for front doors
When front doors open outward, they are often swept by the wind at many locations and slam open without control. For this reason, back checks are often installed on front doors that open outward. The cushioned opening speed and limited opening angle help protect residents and visitors and prevent damages.
Back checks for garage doors
Back checks are also often used on garage doors that open outwards. This is because, unlike floor stoppers, back checks do not pose a trip hazard and the door is dampened when it opens too quickly, so that it does not slam open without control.
