How to choose the right door closer for your application
Door Closers play an important role in the overall fire safety of your building or premises, but with so many different configurations available, it can be hard to know which one is right for you. Today we’re going to take a closer look at the features available in a door closer to help you decide which unit is right for your application.
Overhead door closers are widely preferred over concealed door closers, as a concealed closer requires a large section of the door to be cut away to house the body of the closer, thus reducing the fire integrity of the door.
Door closers are assigned a size or “strength” between 1-7 based on the size and weight of door they are capable of controlling. Higher numbers correspond with the ability to control heavier doors. Door closers are assigned either a fixed power size (e.g. Size 2) or an adjustable power size (e.g. Size 3-4). An adjustable power size is popular for applications where the strength required is not known at the time of purchase, as these can be adjusted during installation.
Some door closers feature a Hold Open function, which means they are able to hold open the door at a 90 degree angle until closed manually. We recommend you consult with your local building authority before fitting these to you building as they may not be suitable for certain applications, such as fire doors.
Many door closers allow for the closing speed of the door to be manipulated to suit the needs of your staff and patrons. The four features which impact the speed of the door movement when opened or closed are delayed action, backcheck, adjustable closing and adjustable latching.
