Key Features
Interior thumb-turn plus a keyed exterior cylinder with 3 identical keys.
72 hour salt spray test and 810mm drop impact test per the listing.
Rated for 250,000+ rotations and 10+ years of use.

Design and Build Quality
Construction uses reinforced zinc alloy, rated by the listing for 250,000 or more rotations, equating to a stated 10 or more years of use. A patented internal mechanism is designed to prevent jamming, and the handle supports doors up to 45mm thick. The 123mm lever length is built to reduce wrist strain compared with a shorter handle, and 65mm rosettes are sized to conceal mounting screws for a cleaner look.
The latch adjusts between a 60mm and 70mm backset, 2-3/8 inch or 2-3/4 inch, fitting standard doors from 35mm to 45mm thick, 1-3/8 inch to 1-3/4 inch. Handing is reversible for left or right opening doors without needing extra tools.
Performance in Everyday Use
The precision machined mechanism is stated to keep operating smoothly through thousands of daily open and close cycles while maintaining tight security from both the interior and exterior lock points.
Installation is framed as straightforward, with English instructions, all hardware and a stated 10 minute install time for a typical door, plus a square latch plate meant to keep proper alignment on wood doors.

Who Should Buy It
- Main entry doors needing keyed exterior access
- Bedroom doors wanting an interior thumb-turn lock
- Garage doors needing a durable, corrosion resistant handle
- Buyers installing on standard doors between 35mm and 45mm thick
- Doors thicker than 45mm or thinner than 35mm, since the latch is only rated for that thickness range
- Listing does not provide a stated item weight for the handle set
- Fits doors from 35mm to 45mm thick only, so unusually thick or thin doors may not be compatible
- Only one finish, polished chrome, is offered in this listing
- 3 included keys are identical to each other, so losing all 3 means rekeying rather than relying on a backup with a different cut
