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 door closes poorly despite an otherwise sound visible opening or the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Causes: local damage to an accessible component rather than an assumed structural defect or loose fixings, minor alignment drift or ordinary timber movement.
Adjustment options vary by model. A suitable closer can be checked within its permitted range, but stiffness may also relate to hinges, alignment or seals. The enquiry should describe the movement rather than assume turning an adjustment screw is the complete repair.
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.
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.
