Concealed hydraulic door closer JNF ML.21.801 up to 100 kg

The concealed hydraulic door closer JNF ML.21.801 is a high-quality, durable closer from the Portuguese manufacturer JNF. It keeps doors in residential buildings, offices, public buildings and washrooms reliably closed at all times.

The body is made of aluminium in grey and is built invisibly into the door leaf, so the closer stays almost unnoticed and the door keeps a clean, discreet look. The slide rail comes in an anti-vandal design, which makes it particularly resistant in heavily used areas.

The closer shuts the door quietly and in a controlled way, prevents slamming and reduces heat loss. Closing speed and latching action are finely adjustable via two valves, the closing force is fixed at EN 3 and the hold-open function can be removed if required. The model is certified to EN 1154, fire rated to EN 1634 and CE compliant.

It is mounted with screws on left-hand or right-hand doors. The package includes the slide rail with slide arm, mounting screws and mounting instructions.
