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 closes poorly despite an otherwise sound visible opening. Causes: loose fixings, minor alignment drift or ordinary timber movement or local damage to an accessible component rather than an assumed structural defect.
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.
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.
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.
