Single-Sided Mechanical Gate Code Lock for 30-50mm Box Section, Free Exit, Silver

This is a single-sided mechanical code lock for swing gates made from 30mm to 50mm box section: a push-button keypad on the outside so people need a code to get in, and a plain lever handle on the inside so anyone can always get out. It needs no batteries, mains power or cabling, so it brings keypad access control to any metal gate without an electrician. The silver aluminium case holds a stainless steel mechanism with an adjustable polyamide rollerbolt, and the E-coated lock box is salt spray tested for 1000 hours. The price shown is for one lock with handles; the keep is sold separately.

Why use this code lock

Coded entry, free exit. The keypad is on one side only, so visitors need the code to come in, while children, residents and staff can leave without one. It suits school and nursery gates, communal gardens, play areas and offices where a safe, easy way out matters.

No power, nothing to fail. The lock is fully mechanical: no batteries to change, no wiring to run along the fence and nothing to go flat in winter.

Codes you can change in minutes. The access code is quick to set up and change whenever it gets passed around. After the gate opens and the handle is pushed, the code resets on its own, and an integrated press plate stops the code being found by feel.

Smooth, adjustable closing. The polyamide rollerbolt lets the gate close easily, and the bolt adjusts continuously by 20mm so it lines up with the keep even if the gap between gate and post is not exact.

Built for outdoors. Stainless steel push buttons, a polyamide rain and dust cover over the keypad and an E-coated lock box tested to 1000 hours of salt spray keep it working in the weather.

Where it is used

Pedestrian gates at schools and nurseries, communal gardens and bin stores at blocks of flats, play areas, sports clubs and tennis courts, offices and depots, wherever entry should be by code and exit should be free.

Choosing the right option

Choose this single-sided lock when people need a code to come in but must be able to leave freely. Where a code is needed in both directions, choose the two-sided lock. Check the gate stile: this lock is made for box section from 30mm to 50mm. The lock does not come with a keep, so order a standard keep for everyday gates or the security keep where the gate is pushed hard or tampered with, and fit a safety cable at the hinge side of any swing gate.

Fitting and care

Fix the lock to the face of the gate stile with the fixings supplied, fit the handles, then fit the keep on the post so the rollerbolt lines up. Set the bolt depth with the 20mm adjustment, set your code following the instructions and test it with the gate open before closing it. Keep the rain cover shut when not in use, wipe the case with warm soapy water and do not paint over the keypad or bolt.
