About power-adjustable door closers
At the moment, there’s a problem. Countless building owners, building managers and estate
managers have holes in their fire doors. Holes that have appeared as a result of moving a door closer
to a slightly new position, usually because the fixed-power door closer wasn’t functioning properly –
something that happens frequently.
The thing is, these holes are not just unsightly, but they could pose a serious threat in the event of a
fire. After all, the purpose of a fire door is to form a reliable blockade against a fire, allowing sufficient
time for evacuation.
Fire doors and hardware are a complex combination and a great deal of work goes into their design,
testing, and re-testing to ensure that they work together as a reliable system – a door set. The entire
assembly has been specifically designed to contain fire and delay its spread, and yet these small
holes could be compromising the safety of everybody in the building.

Of course, extraneous holes can be avoided in the first place by fitting power-adjustable door closers, such as the Rutland TS.11205, TS.11204, TS.5204 and TS.9205 – installing the closer in the intended location on the door, and adjusting the power setting to suit the application. Some adjustable door closers also feature adjustable door closing time, closing delay, and even back-check functionality to stop the door from being slammed open.

Fire safety should be a top priority for every building. When fire safety is truly integrated within a
building’s construction, lives are saved, and property is protected. Door controls, and particularly power-adjustable door closers, play a critical part in the overall integrity of a building’s fire defence, and it’s important to get it
