Sizing & measurements

Door Handle Backset Guide: How to Measure and Choose

Backset is the distance from the door edge to the centre of the spindle hole. 60mm is the Australian standard, but 45mm and 70mm are common — and mortice locks run their own sizes entirely. How to measure yours in thirty seconds, and what to do when the numbers don't match.

Covers 45mm / 60mm / 70mm tubular latches · 44mm / 46mm / 57mm mortice locks · narrow-stile and rebated doors

Materials & finishes

Coastal Door Hardware: Which Stainless Grade, 304 or 316?

316 marine grade resists the salt that pits 304. Which grade for which distance from the surf, why tea staining isn't a fault, and how to keep a manufacturer warranty intact.

Choosing a Door Hardware Finish

Which finish suits your doors, your climate and the rest of your home.

Twelve finish families, two very different behaviours. Some finishes hold their colour for life; others darken and patina by design. This guide explains which is which, what suits a coastal build, and how to mix finishes across a home without it looking accidental.

Functions & compliance

Functions & compliance Passage, Privacy, Entrance and Dummy: Door Handle Functions Explained.

Two handles can look identical on the shelf and behave completely differently once they're on the door. What each of the four functions actually does, what each one needs alongside it — a latch, a cylinder, a catch — and a room-by-room table covering every door in a typical Australian home, from the front entry to the walk-in robe. Covers passage latches · privacy turns and emergency release · entrance single vs double cylinder · dummy handles and ball catches · French doors, cavity sliders, fire doors and AS 1428 washrooms
