Locinox mammoth-hd-silv Hydraulic Gate Closer Hinge Set 440 Lbs

Product Description

The LOCINOX mammoth-hd-silv is a heavy-duty hydraulic gate closer and hinge-in-one unit designed to reliably close gates weighing up to 440 lbs (200 kg) and spanning up to 2000 mm in width. The set pairs the hydraulically damped Mammoth closer with the self-closing Raptor hinge, delivering a smooth, controlled close through a patented hydraulic damping system. The Active Thermal System maintains consistent closing speed regardless of temperature swings or humidity, making this unit suitable for year-round exterior installation. Both hinges use double bearings for exceptionally smooth operation. This unit is installed by gate fabricators, fence contractors, and commercial door hardware technicians.

The mammoth-hd-silv is suited for residential and commercial swing gate applications where heavy gate weight and wide gate spans require a robust, weather-resistant closing solution. The 180-degree closing angle eliminates the need for a separate gate stop. ADA-compliant opening resistance of less than 5 lbs applies to gate widths of 4.6 feet and up, making it appropriate for accessible entrances in commercial and institutional settings. The silver finish suits ornamental iron, aluminum, and steel gate frames commonly found in perimeter fencing installations.

Installation Notes

Installation is typically performed by licensed fence contractors or commercial door hardware technicians familiar with gate hardware and applicable local codes.
