door closer installation and repair can be appropriate when the door sags, rubs, sticks or has uneven gaps around the opening. Check the closer model against the ordinary door, mounting support and manufacturer limits before fitting or adjustment.
Signs: the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally or the door sags, rubs, sticks or has uneven gaps around the opening. Causes: normal wear in hinges, latches or compatible mechanical hardware or loose fixings, minor alignment drift or ordinary timber movement.
The supplied template establishes bracket and body positions for the permitted arrangement. Existing holes may not match a new model. Sound ordinary fixing support is required; installation does not include structural reinforcement or modification of a rated opening.
A closer needs to suit the door it controls. Provide leaf dimensions and product weight where available. An oversized or undersized unit should not be compensated for with extreme adjustment, and unsupported heavy doors need a different handling assessment.
adjust and retain suitable existing hardware. replace an identified compatible component after measuring the existing item. Limits: Ordinary non-rated surface-mounted mechanical units only. No fire, smoke or egress certification, powered systems, structural reinforcement or specialist mechanisms.
