Lockey TB 200,400,600,250+,450+,650+ Hydraulic Gate Closers

Lockey TB Hydraulic Gate Closers include the following models: TB200, TB400, TB600, and the adjustable TB250+, TB450+, TB650+ gate closers.

These automatic gate closers do not slam gates shut like most closing springs. Instead, they firmly push a gate closed at a controlled speed and pressure. This saves wear and tear on the lock and other latching devices and ensures that the gate is closed, latched, and locked automatically (depending on the lock), each time it is closed.

We also carry the Lockey TB175 hydraulic gate closer.
