Insert Lock Kit for 40mm Box Section Gates, Older Pattern Cut-Out, Black

A replacement insert lock kit for 40mm box section gates that were cut for an earlier pattern of lock body. If you are replacing a worn insert lock and the slot in your stile does not match the current lock case, this is the kit to look at before you start cutting the post again. It is a full kit in black, made up of the lock, two aluminium cover plates, a cylinder, a black aluminium handle set and a keep, so an old gate can be brought back into service from one order. The backset is 20mm. It suits metal, aluminium and PVC gates built from 40mm profile, and it fits an older style cut-out, so check the slot in your gate before you order it.

Why this kit works

It answers the awkward repair. The expensive part of replacing a lock on a finished gate is cutting and repainting the stile. This kit is intended for the older style of box section cut-out, so the gate does not need to be remade around a new lock.

Stainless where it matters. The mechanism, hook, front plate and latch bolt are stainless steel, the right choice for a lock that sits outdoors and gets used all day.

A hook that anchors. The hook has a 21mm throw into the keep, and with the right keep the gate leaves cannot simply be pulled apart.

Adjustment without dismounting. The day bolt adjusts continuously by up to 10mm, and it changes easily between left and right.

Where it is used

Repairs and replacements on gates that already have an insert lock slot, typically gates of a few years old on commercial premises, housing and public buildings. The kit is black, so match it to the colour of the gate and the handles already on site. It is a swing gate lock and not for sliding gates.

Specifications

Choosing between the patterns

The whole question here is the slot. Before ordering, take the old lock out and measure the length and width of the cut-out and the position of the fixing holes, and send us those measurements or a photo if you want a second opinion. This kit is the older pattern. A gate cut for the current lock body, or a new gate, should use the current kit, which has a published 176 x 22mm cut-out. Do not assume a replacement will fit just because the box section is 40mm.

Fitting and care

Remove the old lock, clean up the slot and check for rust at the cut edges, and treat any you find before the new lock goes in. Slide the new lock in and clip it home, fit the cover plates and handles, then the cylinder. Refit or fit the keep so that the hook enters without binding, and set the day bolt so that the gate closes without slamming. We recommend a safety cable on all swing gates.

Keep the fore plate slots clear of grit and check the handle fixings at routine maintenance. Replacement cylinders can be keyed to match others on the site.
