COMBI 787 Double-Locking

Fadini 7877BB3L COMBI 787 Heavy-Duty Underground Hydraulic Swing Gate Operator - 110¡, Double-Locking

The Fadini COMBI 787 7877BB3L is a double-locking underground hydraulic swing gate operator built to hold heavy leaves firmly open or closed. Rated for leaves up to 6 m and 1,000 kg with 110¡ shaft rotation, it is made for large residential and industrial gates where a surface-mounted arm would look out of place and a lighter operator would struggle.

The hydraulic control unit and integrated ram sit inside a gate-supporting foundation box, so the drive stays hidden below ground and the operator can be installed or removed without taking the gate leaf off. Adjustable open and closed mechanical stops fix directly inside the box. Bidirectional hydraulic locking keeps the gate secure in both positions. By-pass valves provide anti-crush safety, and on leaves wider than 2 m an electric lock is also required.

Pair it with the 7871L zinc-coated or 7873L stainless steel gate-supporting box and the 7872L manual release set, and you have a powerful, hidden drive for even the heaviest leaves.
