Door Closer Functions Explained

Floor spring. The closer is set into the floor rather than mounted on the door — suited to glass, heavy aluminium and double-action (swing-both-ways) doors.
Hold-open. The door can be held open at a chosen angle and closes normally once released. Note: a mechanical hold-open must not be used on a fire door unless it is an approved electromagnetic (fire-alarm released) hold-open.
Adjustable closing & latching speed. Separate valves let you tune the main closing sweep (about 180°–15°) and the final latching action (about 15°–0°).
Adjustable power (EN size). Sets how much force the closer uses to close the door, matched to the door's width and weight — see the power-size guide below.
Non hold-open versions of this closer simply close after every use, and are the type required on most fire-rated doors.
Other functions offered across this closer range: Backcheck slows the door as it nears the fully open position so it can't slam into an adjacent wall (protecting the hinges, frame and wall) and delayed action holds the door open, or closes it slowly, for the first part of the swing to give extra time for wheelchairs, prams and trolleys. This model includes the functions listed above.

Power size Max door width (mm) Max door leaf weight (kg)

What is a floor spring?

A hydraulic door closer concealed in the floor. It centres the door and controls closing on single- or double-action doors, and suits timber, aluminium and glass doors.

What are the hold-open options?

This series is offered as non hold-open, 90° hold-open, or 105° hold-open depending on the model.

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.

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.
