ERA Warmcore Liniar Passive Slave Bifold Door Lock Gearbox 35mm Backset 92mm PZ

ERA Passive Slave Bifold Door Lock Gearbox

Replacement centre gearbox for matching Warmcore and Liniar bifold door systems, with a 35mm backset and 92mm PZ centres. Designed for the passive/slave intermediate panel, this mechanism operates the existing top and bottom shootbolts through a lever/lever handle arrangement.

Features and benefits

• ERA replacement gearbox for compatible passive bifold door panels.
• 35mm backset: faceplate mounting edge to handle spindle centre.
• 92mm PZ: handle spindle centre to cylinder centre.
• Allows a matching failed centre case to be replaced while retaining suitable existing components.

Check compatibility before ordering

This is the passive/slave version, not the active main-door hook gearbox. Compare the shape, fixing positions, cut-outs and shootbolt connections in our photographs with your original part. A matching backset alone does not confirm compatibility. Please refer to the technical image for the key measurements.

What is included?

One new gearbox only. No faceplate, fixing screws, shootbolts, handles, cylinder, keys or other parts are included.
