Gatemaster BLD4060P Superlock Bolt-On Latch Deadlock for 40–60mm Gate Frames

The BLD4060P is designed to make installation quick and accurate. Only three holes need to be drilled into the gate frame, keeping the process clean and precise. The adjustable bolt length means the lock accommodates slight variations in gate post positioning without requiring additional modification.

The stainless steel latchbolt latches 15mm into the gate post during normal day-to-day use, allowing the gate to be slammed shut without using the key. When additional security is needed, a single turn of the key deadlocks the bolt to a full 30mm throw. This dual-function design means you get both convenience and genuine security from one lock body, without needing to fit separate latching and locking hardware.

Why Choose the Gatemaster BLD4060P

Gatemaster is one of the most recognised names in gate lock hardware in the UK, and the BLD4060P sits at the core of the Superlock range. The slim 70mm case is particularly useful on narrower gate frames where a bulkier lock would look out of place or compromise the structural integrity of the frame. The plain lever handle gives it a clean, modern profile that works well with contemporary aluminium and steel gate designs.

For installations where gate safety and compliance are a priority, note that powered gate automation is regulated by the Supply of Machinery (Safety) Regulations. If you are fitting this lock as part of a wider automated gate project, make sure your full installation meets current safety standards. Our guide on how to make your electric gate safe covers the key requirements in plain terms.
