ERA BS3621 High Security Nightlatch

The ERA BS3621 High Security Nightlatch is a top-tier locking solution designed to replace most standard front door locks with a certified, insurance-approved upgrade. Conforming to the stringent BS3621:2007 British Standard, this nightlatch delivers maximum security and peace of mind for homeowners.

Featuring automatic deadlocking, the lock prevents the bolt from being retracted with tools or credit cards. The internal handle can be deadlocked as well, offering additional protection against forced entry through glass or panels.

A high-security integral cylinder pull is built in to shield the lock barrel against drilling attacks, and the ERA cylinder is supplied with 3 keys as standard. This model is ideal for timber front doors and meets both police recommendations and insurance company requirements.
