Installing A Hydraulic Door Closer

2022-09-09 15:41:40 admin 13

Door closers are common in commercial properties, but can also be installed in residences. Door closers help reduce energy costs by ensuring that doors are always fully closed, which is especially necessary in extremely hot or cold climates.


There are many types of door closers on the market, but in general they perform the same function and have similar installation procedures.


The most common method of door closer installation is called regular arm installation. This is where the closer is installed on the hinge side of an in-swinging door.
