How to install a new door handle
Updating handles can instantly modernise an interior door for minimal outlay. Handles with locks can add extra privacy to bedrooms.
To replace the door handle, check the existing lockset to make sure the replacement matches the hole already drilled, which may suit either 54mm cylinder locks or 35mm tubular locks.
Also measure the backset, which is the distance from the door edge to the centre of the hole.
TIP You can fit the lockset in minutes using a kit such as the Door Lock Installation Kit, about $30, from Ryobi.
