Product Description

This hydraulic door closer is built for controlled swing-door closing in high-traffic entrances where consistent latch action and dependable hold-open performance are required. The closer body delivers smooth damping through the full travel, helping reduce slam risk and improving day-to-day user comfort in offices, hotels, retail spaces, and residential common areas.

A dedicated hold-open function keeps the door in a stable open position around 90°, while the hydraulic system supports automatic closing up to 180°. Two-stage speed regulation allows separate tuning for the sweep and latch zones, so installers can match closing feel to door weight, air pressure, and site conditions.

The design supports left- or right-hand installation without reworking the door, making it a practical choice for maintenance teams and project sourcing. With fitment aimed at wider single swing doors, it is suitable for specification-driven upgrades and replacement cycles where predictable performance matters.
