the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Install a suitable ordinary supplied surface closer, make permitted adjustments or replace an unsuitable leaking unit within the agreed scope.
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: local damage to an accessible component rather than an assumed structural defect or normal wear in hinges, latches or compatible mechanical hardware.
Show the arm’s path and surrounding trim or walls. The door must have the clearances required by the selected arrangement. Moving the arm to avoid an obstruction without following the maker’s instructions can create a different problem rather than a suitable fit.
Keep the instructions available for fitting and handover. Opening range, mounting method and adjustment limits remain product-specific. No compliance certification, fire-door inspection or guarantee of access performance is included in an ordinary mechanical closer installation or repair.
Do not force the closer arm or alter adjustments beyond its instructions. Report a return of uncontrolled closing for review. Limits: Ordinary non-rated surface-mounted mechanical units only. No fire, smoke or egress certification, powered systems, structural reinforcement or specialist mechanisms.
