This latch is one option within the McGrath tubular latch range. The table below shows how the backset, adjustability, fire rating and finish differ across the range so you can confirm the right part for your door preparation.

Frequently Asked Questions
The latch can be set to either 60mm or 70mm to suit your existing door preparation without re-drilling the bore. See standard backset sizes if you are unsure which yours uses.
No. This is a tubular latch designed for a cylindrical bore. It fits into a round hole drilled through the edge of the door.
Fire performance depends on the complete approved door assembly. For guaranteed fire-rated installations choose the fire-rated Satin Stainless Steel or fire-rated Black latch, and read fire door types and smart lock certification.
It is primarily designed for Ascot smartlock installations. Always confirm your backset requirement before ordering. For spare keys or a replacement override cylinder for an Ascot, see the Ascot key blank and Ascot keyed-alike cylinder.
Additional Information
- The adjustable design means one part number covers both 60mm and 70mm doors - useful for installers who do not know the backset before arriving on site. See Chapter 12 - Installation & Troubleshooting for backset-related install checks.
- A wrong-backset latch is one of the most common causes of a smartlock that will not latch or lock. Read common DIY installation mistakes before fitting.
- The SS304 latch tongue resists corrosion in typical residential environments.
