We offer a selection of door closers from leading manufacturers such as Geze, Dorma, Briton and Arrow. Door closers are available to suit all budgets and situations including both manual and automatic doors as well as electromagnetic hold open and swing free applications. The range is complemented with concealed door closers from Geze and Perko for use in situations where a clean, aesthetically pleasing finish to the door is required.
Approved Doc M and BS8300: Relates to accessibility and the code of practice in the design of buildings to meet the needs of disabled people. Swing Free Door closers with adjustable power sizes can help with ease of access throughout a building and will often be specified on new building projects.
Part B: To do with Fire Safety – electromagnetic door closers and holders are Part B compliant. See our blog for more information on this.
We try to ensure that choosing the right door closer for you is as easy as possible and simplify technical terminology so that you know what you’re purchasing. If you are in any doubt and would like assistance with your choice, please contact the sales team on 01305 263300 or email them at [email protected]
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-abled users.
