Sliding Gate Lock for 40mm Box Section, Black, Stainless Hook and Self-Centring Catch

This is a heavy-duty surface-mounted lock for manual sliding gates made from 40mm square box section, in black (RAL 9005): an aluminium lock box with a stainless steel mechanism, a twisting stainless hook finger and a self-centring catch bolt for the post. As the gate slides shut, the cone-shaped catch bolt guides the gate into line and the hook finger turns to lock behind it, so the gate cannot be slid back or lifted off. It comes with a reinforced aluminium handle pair, a key cylinder and keys. The price shown is for one complete lock.

Why use this lock

Made for sliding gates. Ordinary swing gate locks are not built for a gate that slides into its post. This lock and its catch bolt are designed for that movement, and the self-centring catch lines the gate up as it closes.

Hard to cut or force. The hook finger is stainless steel with a stainless collar around it, so it cannot be sawn through to free the catch bolt.

Flexible fitting. The catch bolt can be mounted horizontally or vertically to suit the post, and the lock fixes to the stile with two socket head screws.

Built for outdoors. The lock box is E-coated and salt spray tested for 1000 hours to ISO 9227, with a stainless mechanism inside, for exposed and coastal sites.

Where it is used

Manual sliding pedestrian and vehicle gates in 40mm box section at industrial units, yards, depots, car parks, schools, business parks and homes with sliding driveway gates.

Choosing the right option

Measure the end stile of the sliding gate: this lock is for 40mm square box section, with versions for 40mm, 50mm and 60mm. Choose black to match a black gate, or silver for grey or galvanised gates. Where the gate is being made new and you want the lock hidden inside the stile, a mortice hook lock is the alternative.

Fitting and care

Fix the lock to the face of the gate's end stile with the two socket head screws, fit the handles and cylinder, then fit the catch bolt to the receiving post, horizontally or vertically, so it lines up with the hook finger as the gate closes. Slide the gate shut a few times to check it centres and locks cleanly. Keep the catch bolt clean and put a little graphite in the cylinder once a year.
