What size door does it suit?
Overhead closers are power-adjustable; the size range in the product title (e.g. EN 1–4) indicates the door widths/weights it covers. Contact Prime Hardware if you need help matching a size.
What do delayed action, hold-open and back-check do?
Delayed action pauses the door open before it closes; hold-open keeps it open at a set point; back-check cushions the door if it is thrown open. Only the functions named in this product's title are fitted.
Can it be mounted on either side?
Yes — these closers suit push or pull side; slide-rail and parallel-arm options give a lower-profile or flush installation.
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.
Standard arm, parallel arm or slide rail — what's the difference?
A regular (standard) arm mounts on the push side. A parallel arm mounts on the pull side and sits flush to the door — popular in commercial buildings because it resists damage. A slide-rail arm runs in a low-profile track for a neater look. Top-jamb mounting is used on outward-opening doors.
Is this finish in stock?
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?
Lockwood products carry a 25-Year Mechanical Warranty against defects in materials and workmanship. Electrical/electronic components, where fitted, carry a separate electronic warranty. Manufactured by ASSA ABLOY Australia.
