Overhead closers are versatile and useful. All will close the door, to limit further access or maintain internal environments. Depending on the model chosen, they can also:
- Control the opening and closing speed – useful in windy situations.
- Restrict the door opening angle, to prevent damage to doors and the reveal corners.
- Hold a door open - useful when carrying goods through.
- Delay closing – helpful for parents with buggies or people with limited mobility.
- Fire rated doors must be fitted with a self closing device so that the doorset will resist the spread of fire. If these doors need to be held open in normal use, we can fit electro-hydraulic closers linked to the building’s fire alarm system.
Surface mounted closers are available in several finishes, to complement the chosen colour scheme.
Concealed closers are useful in some situations:
- Not visually intrusive – can promote a minimalist look
- Will allow doors to be opened nearer to adjacent walls or other obstructions. The closer body does not protrude from the surface of a door, nor does its arm stick out.
- Can be helpful in anti-ligature regimes.
- Are less susceptible to vandalism.
Adjustable telescopic limit stays are a budget alternative to closers. They can:
Restrict the door opening angle to prevent damage to doors and the reveal corners.
Be tightened to hold a door open.
Powered operators are often fitted to main entrance doors to allow unimpeded entry and exit of pedestrians from a building. They can also be useful when:
- Carrying goods through
- Pushing trolleys through
- Driving vehicles through
- Linked to access control systems
Inward Opening Doors
On inward opening doors, overhead closers are normally mounted on the pull side of the door leaf, which can result in the closer body fouling an adjacent wall when the door is opened to 90°, for example in narrow corridors where the corridor width is the same as the frame width. The normal solutions are to allow a 100mm wall nib, or to cut a clearance recess into the wall for the closer body. If neither solution is possible, we can build thicker frames or recommend an alternative closer type.Request AutoCAD dwg
