Overhead hydraulic door closer JNF ML.21.610 up to 120 kg

The JNF ML.21.610 is a compact, powerful and durable overhead hydraulic door closer from the Portuguese manufacturer JNF. It keeps doors in residential buildings, offices, houses, public buildings and washrooms reliably closed.

The body is made of die-cast aluminium and steel in grey, with a hydraulic rack-and-pinion mechanism inside. The robust construction provides a long service life and reliable operation in daily use.

The closing force is adjustable via the spring from EN 2 to EN 5, so the closer suits doors up to 120 kg and up to 1250 mm wide, with an opening angle of up to 180°. Closing speed and latching action are fine-tuned with two valve screws, so the door closes quietly and under control, slamming is prevented and heat loss is reduced. The closer is certified to EN 1154 and EN 1634 (fire rated) and carries the CE marking.

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.
