Commercial door closers control how quickly or slowly a door closes, and the type of door closer you choose depends on several factors -- such as your needs, your budget, your building’s architecture, whether you need the door closer for an interior or exterior door, and whether you need a heavy-duty door closer for doors that get a high volume of usage. Barzel Lock offers a wide variety of door closers to meet any need.

We have the most basic types of door closers for light duty applications, to power operated door closers, to electromechanical door closers for applications in which the door will be used frequently by those who are older, are ill, use a wheelchair or have other disabilities. We also offer low-power pneumatic door closers and openers that are helpful in applications where door usage is usually manual, but sometimes automatic operation is needed.

Whether you need a door closer for a school, hospital, retail store, apartment building, nursing home or any other facility, commercial door closers from Barzel Lock make sure the door closes securely but at a safe speed.
