Concealed hydraulic door closer JNF ML.21.800

The concealed hydraulic door closer JNF ML.21.800 from the Portuguese manufacturer JNF closes the door automatically, quietly and in a controlled way. It suits doors in residential buildings, offices, public buildings and washrooms where the door should always stay closed.

The housing is made of aluminium in grey and is driven by a durable hydraulic rack-and-pinion mechanism. The closer is built into the door leaf and the force is transferred through a slide rail with a slide arm, which makes for an elegant, space-saving and almost invisible solution.

The closing force corresponds to size EN 3 and is designed for doors up to 65 kg in weight and up to 950 mm wide, with an opening angle of up to 120°. Closing speed and latching action are fine-tuned with two valve screws, and the hold-open mechanism is removable. Closing is almost silent, prevents slamming and reduces heat loss.

The closer is installed inside the door leaf and is suitable for both left-hand and right-hand doors. The slide rail with arm, mounting screws and mounting instructions are included.
