How to choose the right medium duty transom door closer
- Door type: framed aluminium doors use transom closers, frameless glass doors use floor springs
- Door weight and width: heavier and wider doors need a stronger closer
- Hold open: choose a hold-open closer if the door needs to stay open at 90°
- Floor: a non digging floor spring avoids cutting into tiled or heated floors
- Replacing an old closer: measure the old unit and its cover plate, and send us a photo if unsure
Fitting tips
Fit the closer square to the door and pivot, then set the closing speed and latching speed so the door closes fully without slamming. Test the door several times and check it does not catch fingers at the hinge side. If the door is a fire door, use a closer that is approved for it and check with your fire risk assessor. For more on safe door hardware, see the Door & Hardware Federation.
Looking after your door closer
Check the closing speed and fixings every 6 months, as busy doors wear faster. Oil on the floor or around the closer, or a door that suddenly slams, usually means the closer needs replacing.
