Lock Box 50 x 50 x 3.0mm, 2000mm, Pre-Cut for 50mm Insert Lock

This is a 2000mm length of 50mm x 50mm x 3.0mm steel box section, pre-cut to take a 50mm insert lock: a rectangular opening in the edge for the lock case, plus the holes for the handle spindle and the key cylinder on the face. Use it as the opening stile of a gate and the insert lock simply clicks into place, with no marking out, drilling or cutting of the lock opening on site. It is the matching partner of the 50mm keep box for the post, so the gate and post are ready to lock as soon as the gate is hung. The price shown is for one 2000mm length.

Why use a pre-cut lock box

Accurate first time. The lock opening and the handle and cylinder holes are cut to suit the 50mm insert lock, so the lock fits square and the handles line up without filing.

Saves workshop time. Cutting a clean lock opening in box section is slow and easy to get wrong; with the stile already cut, the gate goes straight from welding to finishing.

Hidden lock, neat finish. The lock sits inside the stile, so only the faceplate, handles and cylinder show, with nothing bolted to the outside of the gate.

Ready to fabricate. Raw mild steel with a 3mm wall, ready to cut to length, weld into the gate frame, then paint, powder coat or galvanise.

Where it is used

Opening stiles of fabricated steel pedestrian gates at homes, schools, offices, industrial units, parks and blocks of flats, wherever a 50mm insert lock is fitted. Fabricators use it with the matching keep box to build gate and post sets that lock first time on site.

Choosing the right option

Match the lock box to the gate frame and the lock: this 50mm lock box suits gates built from 50mm x 50mm x 3.0mm box section with a 50mm insert lock. Pair it with the 50mm keep box as the closing post, or with a surface keep if the post is already in place. For other frame sizes, choose the matching lock box.

Fitting and care

Cut the length to the height of the gate, keeping the lock opening at the lock height you want, and weld it in as the opening stile. Clean the opening of weld spatter before finishing, then prime and paint, powder coat or galvanise, keeping paint out of the lock opening. Click the lock in, fit the cylinder and handles, and check it engages the keep.
