GTS MK3 Latch & Dead Bolt Genuine Multipoint Gearbox - Lift Lever

Product Information
MK3 Serrated Latch Reversal Button

The G-TS lock gearboxes have been manufactured in various versions over the years, making it crucial to select the correct one, as they are not interchangeable. The current G-TS lock began production in 2010 and features different screw fixing positions compared to previous versions.

A reliable way to identify whether you have the new or old version is by checking for the square latch reversal button located next to the latch on the new version.

Maco G-TS gearboxes are designed with lift lever functionality. They measure 228mm in height and have a backset of 35mm, with a width of 18mm. The centres (PZ) measure 92mm.
