Backcheck – Is the cushioning effect you feel when the door is swung open and is prevented from slamming into the wall behind it. It’s a useful feature to ensure that door hardware and the door itself are given a certain level of protection from misuse. Closers with backcheck are also referred to as soft door closers.
Delayed Action/Delayed Close – In simple terms, this means the length of time it takes for the door to close after being opened. It’s often a desirable feature for Care Homes or areas where it may take people a little more time to get through the door unharmed. This function could also be referred to as a door soft closer.
Power Size – This is either fixed at a set number or variable (adjustable). The power size required is determined by the door weight and width. (See Power Size Table below).
Closing Speed – This is the adjustment for the general speed of the door closing. Installers often make the mistake of adjusting this to close the door when first installing a closer, the Power Size should always be adjusted first.
Latching Action – This is adjustable and refers to the final few degrees of closing. This is beneficial to overcome any issues with the latch or seal on a door.
Mechanical Hold Open – A Hold Open Arm can be used on door closers to achieve a rigid hold open function, however these must never be used on Fire Doors.
Hold Open – Electromagnetic Hold Open: Ideal for use on Fire Doors; the Hold Open function means that the door is held open permanently at a fixed angle (unless released by the fire alarm activation). Usually this function is provided in the cam being used, the arm itself or a mechanism inside the slide channel.
Electromagnetic Free Swing – This function means that the door with the electromagnetic closer will act like a door that doesn’t have any closer on it. It means that the door will stay open at whatever angle it is left at but will close in the event of a fire. It’s a particularly good feature to use on Care Home Bedroom Doors when hold open function would cause privacy issues and it meets the barrier-free needs of less-able users.
