Product Overview

The ERA Entrance Lock Door Knob Set Satin Chrome has a style widely used in America and some parts of Europe - the American style passage knob set is not so common here in the UK. All doors must be prepared with a 51mm diameter hole at 70mm from the door edge to use this door knob set.

Supplied with Latch

The knob set has a satin chrome finish. Each set comes complete with a 70mm backset mortice latch, all necessary fittings and full fitting instructions.

Entrance Lock Set

This set has an entrance locking function - this has a centrally located locking turn and is unlocked from the outside by the turn of a key.

There are also other options available; a passage set (suitable for internal doors and as it is a non-locking knob set, it allows free access at all times) and a bathroom privacy set (the external knob on the privacy set has an emergency release, whilst the inner knob has a centrally located privacy turn). 

Note of Caution

Once fitted to a door this type of knob set is difficult to replace, the latch is specific to the American style; and the 51mm hole in the door makes it impossible to fit anything other than American specification knob and lever sets.
