Self closing hinges close doors with no control, no latching speed or little adjustment. Since there is no control of the latching cycle of self closing hinges, a third spring is often needed to slam the door. Whether you have a door closer or a self-closing hinge, they both are made to address the issue of accessibility and the issue of life safety. Door closers are available in different sizes and types and have different features. Both door closers and self closing hinges must be in compliance with local building codes that require certain opening forces and closing speeds.
Door closers are used on a lot of fire doors, storeroom doors, security doors and janitor closets. Door closers give the door its control by using adjustment valves. The valves include back check, closing speed, latching speed and delayed action. You can get floor, surface or concealed door closers. Door closers are less expensive than self-closing hinges.
Self Closing Hinges
Self-closing hinges are designed to pull a door closed after it is opened and released. It keeps you from having to manually close doors. Self-closing hinges are best used on smaller doors. They are also best used on mechanical doors rated for fire such as on the roof or in the basement.
