These spring door closers operate by increasing the direct force of the natural swing momentum of closing the door, and are designed to overcome the slow movement of gaskets and air pressure in order to provide fast and complete closing for heavy walk-in doors. And they are easy to install and can be simply snapped onto a hidden mounting plate. The simple spring mechanism provides a long, trouble-free service life. The steel shell and anti-bending hooks ensure long-term wear and tear during heavy use. Polymer rollers ensure quiet operation. These type of door closers are excellent choice.
