Locinox MAMMOTH-HD Ultra-Heavy-Duty 180° Hydraulic Gate Closer and Hinge – Gates Up to 440 lb
Product Description
The Locinox MAMMOTH-HD is an ultra-heavy-duty hydraulic gate closer and hinge system engineered for gates weighing up to 440 lb and measuring up to 6-1/2 feet wide. It combines the hydraulically damped MAMMOTH closer with the included, powerful RAPTOR self-closing hinge.
Both hinge components feature double bearings for exceptionally smooth gate operation. The adjustable hydraulic mechanism provides precise control over the closing speed and final snap, helping the gate close consistently and engage its latch properly.
Locinox’s Active Thermal System helps maintain a consistent closing speed during temperature fluctuations. The reversible design accommodates left- and right-opening gates, while Quick-Fix mounting supports a fast, secure installation without welding. Its powder-coated aluminum housing is designed for exterior gate applications.
