Where does a transom closer fit?
Into the transom section directly above the door, so it is virtually out of sight when the door is closed. Most of the preparation is done before installation, leaving minimal on-site fitting.
What doors does it suit?
Fire, metal, timber and glass doors with a minimum thickness of 38 mm and a maximum weight of 115 kg.
What is back-check?
Back-check cushions the door from about 80° if it is thrown open, protecting the wall and hardware. On back-check models the maximum opening angle is 90°.
What does hold-open mean?
Hold-open lets the door be parked open at a chosen angle and it closes once released. Important: a plain mechanical hold-open must not be used on a fire door — a fire door may only be held open by an approved electromagnetic (fire-alarm released) device, which drops the door shut automatically on alarm or power failure.
What is backcheck?
Backcheck slows the door as it nears the fully open position so it can't be flung into an adjacent wall — protecting the hinges, frame, closer and wall. It is a cushioning feature, not a hold-open, and is useful in windy or exposed locations. Only closers whose title lists backcheck have this fitted.
What is delayed action?
Delayed action holds the door open, or closes it very slowly, through the first part of the swing before returning to normal speed — giving extra time for wheelchairs, prams, trolleys or moving furniture. It is common in hospitals and aged care. Only closers whose title lists delayed action (DA) have this fitted.
What do the EN power sizes mean?
The EN power size (EN 1154) sets the closing force, and each size is defined by the door leaf's width and weight. As a guide: EN1 up to 750 mm / 20 kg, EN2 up to 850 mm / 40 kg, EN3 up to 950 mm / 60 kg, EN4 up to 1100 mm / 80 kg, EN5 up to 1250 mm / 100 kg, EN6 up to 1400 mm / 120 kg. A range such as EN 1–4 means the closer is adjustable across those sizes — a wider or heavier door needs a higher power size.

Silver and Black finishes are normally held in stock with the supplier. All other finishes (and no-finish/raw components) are made to order — call Prime Hardware on 1800 329 028 to confirm availability and lead time before you order.
What warranty applies?
