Window and Door Gearboxes

HOPO window and door gearboxes play a significant role in providing exceptional sealing effect and ensured security to PVC window and door fitting.

1. Outstanding Corrosion Resistance
Our furniture hardware is endowed with special zinc-nickel plating surface finish. When being applied to inland areas, our PVC lockcase has the capability to remain corrosion resistant for as long as 15 years!

In order to withstand rigorous environment in coastal areas, we provide stainless steel gearbox and 16mm groove inward tilt-turn hardware fittings. In addition, PVD (physical vapor deposition) surface treatment is also available to ensure 10-year corrosion resistance.

2. Remarkable Flexibility
Our window and door gearboxes are presented in various center distances in fit diverse profile sizes. Gearbox selection is based on profile design and characteristics. Please contact our technicians for technology support.
