What the transom channel had in it
The photographs from Kingswinford are a good illustration of why a concealed transom closer fails long before its hydraulics are worn out. The channel in the transom bar is open to the top of the door, and over the years it fills with the dust, grit and fibre that a sports hall produces by the bucketful. The arm pivots run in that debris and wear oval; the spindle bolts in the bottom track sit in whatever water finds its way through the threshold and rust in place. By the time the closer itself loses control of the door, the parts around it are in no state to drive a new unit. The two old closers on the gym floor and the handful of rusted spindle bolts in the track are what came out.
Each replacement therefore went further than swapping the closer. The channel was cleared and cleaned, the spindle bolts and pivot block renewed where they had corroded, and a new arm fitted with the closer so that the whole chain from closer spindle to top rail started from zero wear. The new arm in the top rail, bright against the white frame, is in the photographs beside the old one.
Sports hall, fitness suite, double exit
The three doors each serve a different space. The sports hall door opens onto a sprung timber floor and is worked by every class that uses the hall; the fitness suite door opens straight onto the rubber-floored gym with its rowing machines and exercise bikes; the double door at the end of the walkway is a straightforward escape route. All three are fire exits with running-man signs and all three need to close themselves reliably, because a school escape door that stands open is an unsupervised way in as much as a way out. This is the same reasoning behind the closer programme at Westglade Primary School in Nottingham and the café door at Kingston Grammar School.
Working on a live school site
The visit was made during the school day. Each door was taken in turn with the opening barriered and the room behind it kept clear while the leaf was off, so the sports hall lost its external door for an hour or so rather than the whole block losing access for the day. Tools were kept inside the taped area, the leaf was leaned flat to the wall where it could not be knocked, and the door was re-hung and tested before the barriers moved to the next one. Our education sector page sets out how we work in term time and what we schedule into half-terms instead.
Work completed at Kingswinford Academy
- Scope — three concealed transom closers replaced on white aluminium external doors: sports hall fire exit, fitness suite door, double-door exit.
- Removal — each leaf lifted off its pivots; old closer, arm, corroded spindle bolts and debris cleared from the transom and threshold track.
- Installation — new concealed closer and new side arm on each door; fixings renewed; leaf re-hung and speeds set.
- Access — term-time visit; one door barriered at a time; rooms kept clear while leaves were off.
- Handover — all three doors closing and latching under control the same day.
School door repairs around Dudley and the Black Country
Commercial Door Maintenance and Security Ltd attends schools and academies across Dudley, Kingswinford, Stourbridge, Brierley Hill and the wider West Midlands for closers, fire doors, panic hardware and roller shutters. A photograph of the door head and the threshold is usually enough for us to identify the closer and quote a replacement before anyone visits.
