Sterling floor springs,
60 to 120 kg.

A floor spring is a door closer set into a recess in the floor under the door, with the door pivoting on it. Nothing is fitted on the face of the door, which is why floor springs are used on glass doors and on heavier entrance doors.

Choose by door weight. The FS 1000 is rated for doors of 60 to 80 kg. The FS 3000 is rated for doors of 90 to 120 kg. The FS 3000 uses a cam action body with a load adjustment screw to match the spring load to the door weight. Both suit doors up to 1100 mm wide and 2100 mm high. A door between 80 and 90 kg is outside both rated ranges: send the door details with the quote request.

Floor springs suit glass doors and heavier doors where nothing should show on the door. Overhead door closers suit most wooden and aluminium doors and are simpler to retrofit. The guide on this page compares the two.

Yes. Sterling does not publish list prices, because the price depends on the model, finish and quantity. Send a door schedule with leaf widths, door weights, mounting type and quantities, and we will size and quote every door against it.
