Lockey Replacement Cylinders for Gate Closers (TB200,400,600,250+,etc)

If you need only the hydraulic cylinder for a Lockey TB-Series Hydraulic Gate Closer and not the post/gate mounting brackets, then order one of these hydraulic cylinders for sale. However, if you need both the hydraulic cylinder and the mounting brackets, click here to order gate opener parts: Lockey TB-Series Gate Closers.

Lockey TB-Series (TB200, TB400, TB600, TB250+, TB450+, TB650+) Hydraulic 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 a gate is closed, latched, and locked automatically (depending on the lock), each time it is opened.

NOTE: LockeyUSA is discontinuing these replacement cylinders. As soon as their current inventory is sold out, you will only be able to order the whole gate closer (TB200,400,600,250+, etc). Stock up now while supplies last.
