Overhead hydraulic door closer JNF ML.21.600

The hydraulic door closer JNF ML.21.600 from the Portuguese manufacturer JNF is a durable, well-made overhead closer. It closes the door automatically and in a controlled way, wherever a door has to stay closed.

The closer is made of die-cast aluminium and steel and works with a long-life hydraulic rack-and-pinion mechanism. Its compact build and the choice of materials give stability and a long service life in daily use. It is available in grey or black.

The closing force is adjustable in sizes EN 2–4, with additional force adjustment through the choice of mounting position. Closing speed and latching action are fine-tuned with two valve screws. The closer is rated for doors up to 80 kg and 1100 mm wide, with an opening angle of up to 180°; it is certified to EN 1154, fire tested to EN 1634 (fire rated) and CE marked.

It is surface mounted on the door leaf and suits both left-hand and right-hand doors. The package contains the door closer, a standard arm, mounting screws and mounting instructions.
