You can see door closers in the majority of commercial buildings. They are nothing but mechanical devices installed to guarantee that the doors close after residents, patrons and other users open them. Building codes typically determine what exits should be equipped with door closers from a door closer manufacturer.
Some might require all doors to have them. Most areas need them on fire doors; the reason is that fire doors should stay closed always when not in use. This helps make sure that flames do not open out from one part to another part of the building before firemen reach the place and bring the fire under control. Door closers come in two types; automatic and manual.
Manual closers
The manual door closer type from the best door closer supplier is the most common one. Over 70 percent of manual closers can be found in commercial buildings. Manual closers might be jamb mounted or overhead mounted. The latter is a common style specifically on older buildings. The former is a device that is fixed on the door’s inner frame and the door’s inside edge. You can see the mechanism only when you open the door. After it closes, the jamb-mounted device is hidden on the exterior and the interior side.
Automatic closers
These closers from the door closer manufacturer utilize electrical power rather than stored energy. This is a less common style owing to the amount of power needed and the interest of conservation and economy. Automatic closers are mostly found in buildings wherein specific exits/entrances are controlled and monitored and people need to buzz in/out like residential care homes.
Verdict
Door closers are concealed or surface mounted and are named as to how they are fixed on the door. Concealed devices from the door closer supplier are mounted within the door material itself and the arm is the only visible part while the surface mounted devices look to be a tiny box that is fixed to the door’s top corner. A jointed arm expands from the box top to the frame where it is secured in.
