Hydraulic door closer JNF ML.21.550.BA with slide rail

The hydraulic door closer JNF ML.21.550.BA from the Portuguese manufacturer JNF is a high-quality, durable closer with a slide rail. It is fitted to doors in residential buildings, offices, public buildings and sanitary areas where the door should always stay closed.

The body is made of die-cast aluminium, while the mechanism and the slide rail are made of steel. The durable hydraulic rack-and-pinion mechanism works quietly and ensures a long service life in daily use, and the slide rail with slide arm gives a neat look and smooth door movement.

The closing speed and the latching action are adjusted precisely with two valve screws. With closing force EN 3 the closer is designed for doors up to 60 kg and up to 1000 mm wide, with an opening angle of up to 180°. It provides almost silent, controlled closing, prevents slamming and reduces heat loss.

The closer is surface-mounted on the door leaf with the supplied screws and suits left-hand and right-hand doors (DIN left and DIN right). The package contains the closer, the slide rail with slide arm, mounting screws and mounting instructions.
