What happens with the wrong size?

Too small and the door is left ajar; too large and it slams shut, damaging the door and frame over time.

Slide rail or scissor arm?

The scissor arm is surface mounted and the most common answer; the slide rail runs in a track, looks cleaner and suits narrow openings.

Can the closing speed be adjusted?

Yes. Valves on the closer body set the general closing speed and the final latching speed separately.

Door Closers

A door closer brings the door shut at a controlled speed and stops it slamming. The one critical decision is the size — the power class matched to the weight and width of the door. The catalogue holds 16 models.

Size, mounting and adjustment

The size is the power class matched to door weight and width: size 2 for light interior doors, 3 for standard doors, 4-5 for heavy and wide ones. Too small and the door never closes; too large and it slams. Adjustable-power models cover a range.

The scissor-arm type is surface mounted and the most common solution; the slide rail type replaces the arm with a track, looks cleaner and suits narrow openings; concealed types hide inside the leaf. Closing speed and latching speed are set on separate valves, and on fire doors the closer must shut the door fully.
