Yale has launched the first retrofit multipoint lock to allow users to maintain accreditation on existing PAS 24 doors without needing to fit exactly the same lock as was supplied with the door.
Trade professionals can now fit a suitable replacement on the first visit from a small range of van stock.

PAS 3621 Doormaster will maintain PAS 24 accreditation on existing doorsets providing no alterations are made to the doorset. It can also upgrade the level of security when replacing an existing multipoint lock on doors fitted with a lower specification.

PAS 3621 is a direct multipoint equivalent to the BS 3621 single point standard and aims to provide a benchmark for selecting appropriate products with the correct level of security.

As with BS 3621 locks, PAS 3621 locks are tested to the equivalent side load forces and test methods.
