Lockey Gate Closer GC400  is an economic and reliable hydraulic gate closer for use with commercial and domestic gates.

Unlike normal closing springs, the Lockey Gate Closers do not slam gates shut. They firmly and quietly push gates closed, making them ideal for use with electric/magnetic locks, and other latching devices including Lockey digital door locks.

The gate closer closing speed is pre-set to give a controlled closing time; this can vary slightly depending on the weight of the gate and condition of the hinges.

Please Note: this Operator may be too powerful for shorter Gates

Installation essentials
Here are a few essentials that will ensure your installation is successful.
1. Make sure hinges are freely moving and lubricated

2.Test the gate swing to find out if the gate drops and repair if necessary

3. Make sure post and gate are vertically and horizontally aligned

4. Post and gate bracket must be horizontally aligned

5. Fit one gate stop (normally the lock performs this function) to restrict the swing of
the gate from passing through the post line when the gate closes.
A second gate stop to restrict the opening angle of the gate to 90 degrees (Failure to fit gate stops will invalidate your warranty) 

6. Use good quality strong fasteners to secure the gate closer brackets (not included)

Gate closer force is increased by using mounting holes further away from the gate post. 

With this closer there is no risk of maladjustment or tampering with the speed adjustment after the closer is fitted.

Our Lockey Gate Closer is extremely simple to install and only require periodic inspection and joint lubrication.

Most gates have an in-line hinge arrangement, if the gate you have has a different hinge arrangement ie Off-Set, please refer to the Gate closer brochure available for download on the home page or  If the information provided does not help then please contact us for advice.

Each Lockey gate closer kit includes fixing brackets, fitting bar and instructions. Fixings are not included. Button socket head screws are suitable for metal fixing and a similar low profile is suitable for timber fixing.

Alternatively, brackets can be welded to post and gate.

As with most gate closers, it is advisable to fit a mechanical stop** restricting the gate opening angle to avoid damage to the closer.
