For HOME SECURITY the ERA BS Nightlatch or the double locking door high security Nightlatch are the business.

If you are looking for a reasonably priced security rim lock the ERA BS Nightlatch, both the narrow style and standard sized locks, are the choices, they can be bought through our web shop, by following this link. Both of these ERA BS Nightlatch systems can be fitted to aluminium, UPVC or composite doors, to prevent the easy access through these types of doors.

The other ERA Nightlatch, which is non British Standard, but would be ideal for internal flats as well as doors with glass or UPVC and aluminium doors, are the ERA narrow 40mm and standard 60mm Nightlatches, these can be locked from the inside and automatically deadlatch, when closing the door.

Both sizes of this ERA Nightlatch can be bought from the web shop of Master Locksmiths, see below.

The ERA Double Locking Nightlatch is available in both 40mm (Narrow) and 60mm (Standard) back set, designed to replace most existing front door locks.

The product is ideally suited for solid and glass panelled wooden doors, as it has been designed with an ergonomic internal locking handle offering added security against forced entry.

The main lock bolt is “automatically” deadlocked when the door is closed, preventing the main bolt being retracted by a credit card.

The inside handle can be deadlocked by an anti-clockwise turn of the key from the inside so securing the lock against forced entry.

The lock comes with 3 keys.

Master Locksmiths trades as the web shop of North London Locksmiths Ltd. the Locksmith Company trading from the same premises for the past 35 years, in North London. We send any lock plus keys to anywhere in the UK and Europe.

The bolt can be held in the withdrawn position (only) with the use of the snib feature.

The Nightlatch case is available in Brass, Satin Chrome, and Polished Chrome finishes, with matching rim cylinders.

The Nightlatch has a press button hold back facility, so the door will not close shut, when emptying bins etc.

These locks can be mastered and keyed alike as well as passed or mastered to other cylinders, this can be done at our work shops as well as cutting any extra keys, before being sent out to you.

The bolt cannot be reversed.
