Slim Keep for Insert Gate Locks, 40-60mm Square Posts, Black Stainless Steel, 8mm Visible

A slim stainless steel keep for insert gate locks on square posts of 40 to 60mm. The keep is the half of the lock that lives on the post, and this one is designed to look neat at the gate edge, with only 8mm of visible thickness on the face. It is stainless steel in a black finish, with an aluminium stop plate fitted with a rubber strip, so the gate closes against a soft stop and the lock hook and day bolt meet the keep in the right place. It changes easily between left and right hand and comes with quick-fit fixings and self-drilling screws. Use it with insert locks for 40, 50, 60 and 80mm profiles from our range. Sold with a minimum order of 3, because these are normally bought in numbers for a run of gates or doors.

Why this keep works

Slim on the post. With an 8mm visible thickness, the keep does not stand out from the post face, which suits new gates where the look of the opening matters.

A stop plate that adjusts. The extruded aluminium stop plate moves to suit gate frames from 40 to 60mm, and the rubber strip takes the shock of closing and protects the finish over the long term.

Guide for the day bolt. An adjustable guide stops the day bolt from catching the post as the gate comes in, which is one of the usual reasons a good lock gets damaged on a poor opening.

Quick to fit. The keep comes with quick-fit fixings and self-drilling screws, so a post can be prepared with a drill and a slot rather than welded brackets.

Where it is used

New box section gates and replacements on commercial and domestic sites where the gate is hung on square hollow posts. It is designed for square profiles, so for a round post or a wall you need a different keep or a fixing set.

Specifications

Choosing the right keep

All of our insert lock keeps do the same basic job, so choose by the post and the look you want. This one is the slim black option for square posts. The heavier keep is the one to pick if the priority is resistance to levering, and the surface keep suits a post you do not want to slot.

Fitting and care

Close the gate and mark the height of the lock on the post, then cut the post to suit the keep and drill for the fixings. Fit the keep with the supplied fixings and self-drilling screws. Set the stop plate for your gate frame width and bring the adjustable guide into position so that the day bolt runs in without touching the post. Check that the gate latches on its own and that the hook locks without binding. We recommend a safety cable on all swing gates.

Wipe grit away from the keep and the rubber strip during routine maintenance, and check the screws are tight. Replace the strip if it perishes.
