Lockmaster Single Spindle Gearbox Latch & DeadBolt Centre Case 35mm / 92mm
Lockmaster gearbox Centre Case 35mm / 92mm is a very popular choice for uPVC door manufacturers and installers of late, due to the smoothness of the operation and reliability offered at a great price. Although it is a fairly modern design, its failure is normally down to a misaligned door as excessive force is applied when lifting and lowering the door handle to compensate for this.
We advise you to adjust the door accordingly after installation of the new Lockmaster gearbox centre case, to prolong the life of this very popular replacement part.
