Materials and durability
The lock is made entirely of stainless steel with a brass latch and has been tested to 1,000,000 openings, which makes it one of the most robust mortice locks available.

The lock is operated with a key and a handle. It comes in two versions: ML4 DC with dual cover escutcheons and ML4 FC with a full cover escutcheon.
Sizes and fit
The lock fits 1-9/16" box section and has a 13/16" backset. A bolt-on keep plate, a eurocylinder, cover plates and handles are supplied, so the lock arrives ready to fit with a stainless steel keep for the hook bolt to close into.

Frequently asked questions
Will it survive outdoors all year?
It is built for it. The bodies are pressure die-cast and powder-coated, latchbolts are stainless steel and the keypads are marine grade, so salt air and rain are not a problem. Follow the maintenance schedule on this page - a spray of light oil a few times a year is what keeps a gate lock feeling new after a decade outside.
What warranty comes with this product?
Gatemaster gives a 5-year warranty on the Superlock 2.0 range and a manufacturer's warranty on the rest of the program, covering defects in material and workmanship. Keep your invoice: that is the proof of purchase a claim is assessed on. Damage from forcing, from the wrong installation or from missed maintenance is not covered - which is why the maintenance schedule on this page is worth following.
Is this in stock and how fast can I get it?
Gatemaster hardware is part of our standard program, so the common versions ship from stock. If you need a quantity for a project, or you are not sure which version fits your gate, ask us for a quote - we will check the frame size and handing with you before anything is picked.
How do I know whether I need a left-hand or a right-hand lock?
Stand on the outside of the gate - the side you approach from. If the hinges are on your left, you need a left-hand lock; if they are on your right, a right-hand lock. Gatemaster locks in this range are reversible: you loosen the locking screw in the end of the latchbolt with the 0.118" hex key supplied, turn the bolt through 180 degrees and tighten it again.
