Hydraulic door closer JNF ML.21.765 · EN 2–5

The Hydraulic door closer JNF ML.21.765 is a high-quality surface-mounted overhead closer from the Portuguese manufacturer JNF, designed for precise and quiet closing of doors in commercial and residential buildings.

The body is made of aluminium with a silver coated finish of matt appearance. The robust construction and the precise rack-and-pinion mechanism give a long and safe service life.

The closing force is adjustable from EN 2 to EN 5, so the closer covers 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 set with valves, the force with the spring. The door closes quietly and under control, slamming is prevented and heat loss is reduced.

It is surface-mounted on left- or right-hand doors (DIN left and DIN right) with the screws supplied. Note: the closer is delivered without the arm – the arm has to be bought separately, depending on the desired opening and mounting method. The closer takes all JNF arms: the standard arm 21.105.AN, the slide arm 21.101.AN (anti-vandal) (closing force EN 1–3 with it) and the arm with hold-open 21.110.AN.
