You've Got The Key Of The Door, Never Been As Good As This Before

The Yale Lockmaster 21.

Security is the key to lock sales. Launched 21 years after the very first Lockmaster lock was released, Lockmaster 21 from Yales boasts the same reliability and features but with some added benefits.

The company claims that the lock is designed, developed, and tested to deliver the very highest levels of performance, Lockmaster 21 provides PAS 24:2016 security as standard when incorporated as part of a doorset. It also features a new easy-to-use push-in latch/snib feature designed to prevent accidental lock-outs.


 “I was among the first to sell from the original samples of Lockmaster at its very beginnings all those years ago and have sold it consistently ever since then.”

– Paul Atkinson 

Managing director, Yale



“Lockmaster 21 delivers all the features that people know and love about the locking system but with some great added enhancements for both our customers and the end-user," continues Yale's Atkinson. "It faultlessly delivers high-performance security, improved ease of use, and impressive service life. Lockmaster is the preferred lock for fabricators and installers, particularly because of its tolerances making it easy to fabricate, install and it just keeps on working with minimal fuss.”


Hook and pin

Lockmaster’s signature hook and pin unit has been carefully positioned within 100mm of the pre-compression rollers to offer maximum security. With 35mm and 45mm back set options, the range is suitable for the majority of timber, PVC-U, aluminium, and composite door multi-point lock applications in the UK.


Secured by Design

Atkinson adds: “Over the last year or so we have been introducing our long-standing Lockmaster door lock customers over to the Lockmaster 21 and they’ve been really impressed with the innovations that have been made to the range.

“We understand that keeping up to date on the latest security standards can sometimes be confusing, so it is a real benefit to have a product that comes PAS 24:2016 security tested and is Secured by Design approved.”



Yale Lockmaster 21 comes with a 10-year mechanical guarantee, along with a Yale lifetime security guarantee, when used in conjunction with other Yale hardware.
