Sliding gate locks and latches

Which type of sliding gate lock do I need?

• Bolt-on code lock: a practical choice if you want to open the gate with a code. Choose the frame-size version that fits your gate, drill the fixing and latch holes to suit that lock, and check where its latch will meet the keep on the post.
• Key-operated hook lock: this sits inside the gate frame. The frame needs a slot for the lock body and holes for its fixings and key cylinder; the hook must meet its keep when the gate closes. Check whether the listing includes the keep or only the lock.
• Weld-in hook-lock and keypad kit: an option when a new gate is being made or an existing gate is being substantially altered. The lock case needs to be fitted into the gate frame; it is not a quick bolt-on replacement.

Another hook-lock option is the CAIS LOCK L, listed in sliding-gate hardware rather than the product grid here. CAIS DOCK receivers are sold separately in 42, 52 and 62 versions to receive that lock. Choose the DOCK that suits your gate and post.

How do I check the size and fit?

Measure the width of the gate frame where the lock will sit, and check the gap to the post where its latch or hook will meet the keep. Product options can differ by frame size and by which side of the gate they are fitted to, so use the dimensions and fitting diagram for the lock you choose.

Replacing an existing lock? If the same model and size are still available, they are the best starting point for reusing the existing fixing holes and keep. If you choose a different lock, compare the hole positions, lock-body size and latch position first; the gate or post may need altering to make it fit.

Do I need a keypad on one side or both?

The SGLDS sliding lock has a keypad on one side and a handle on the other. Choose the SGLD range if you want a keypad on both sides; it comes in versions for different gate-frame widths. Check the frame-size and left- or right-hand option on the individual product before ordering.

RapidReset is a separate feature: on a lock described as RapidReset, you can change the code without removing the lock from the gate. It does not mean single- or double-sided, and it should not be assumed to be fitted to every SGLD or SGLDS lock.

What if my sliding gate is automated?

These mechanical locks are generally for manually operated gates: a motor must not try to move a gate while a manual lock is engaged. For an automated gate, look at electric gate locks and magnetic locks instead. A magnetic lock is often a straightforward option, but its mounting, power and release must work with the gate motor and controls; ask your installer to specify the complete arrangement.

Do I need a whole new lock?

If just a handle or keep is damaged, you may be able to replace that part rather than the complete lock. Check which model you have and what the individual listing includes. For other lock parts and types, see gate locks and parts.
