Multipoint Gearbox - Lift Lever or Split Spindle

Product Overview: Duraflex Multipoint Door Lock Gearboxes

Duraflex multipoint door lock gearboxes are designed with a unique square shape, featuring no corner cut-outs. They come in two backset options: 35mm and 45mm, with an overall length of 221mm and a width that includes the backset plus an additional 18mm.

Key Features:

• Latch and Deadbolt Dimensions:

  • Latch height: 24mm (with two distinctive screws)
  • Deadbolt height: 30mm
  • Distance between latch and deadbolt: 61mm

• Screw Configuration:

  • Gearboxes are secured to the faceplate with four screws, which is atypical for multipoint locks.

    • First to second: 37mm
    • Second to third: 85mm
    • Third to fourth: 43mm

• Backset Measurement:

  • When measuring the backset, account for an additional 2-3mm for the faceplate. For instance, a 35mm backset gearbox will measure approximately 32mm when not attached to the strip.

Operation:

  • Engage the lock by lifting the lever or using a split spindle.

• Latch Reversal:

  • To reverse the latch, unscrew it, flip it, and reinsert before securing it again.

Product Specification

To ensure you have a clear understanding of the product specifications for the Duraflex multipoint door lock gearboxes, here’s a detailed breakdown of how to measure the backset and centres, as well as an explanation of the operation:

Measuring the Backset:

To measure the backset, follow these steps:

1. Identify the Door Edge: Locate the edge of the door where the lock will be installed.

2. Measure from the Edge: Use a tape measure to find the distance from the edge of the door to the center of the lock cylinder hole. This distance is your backset measurement.

3. Consider Faceplate Thickness: Remember to account for the thickness of the faceplate, which can add an additional 2-3mm to your measurement.

Measuring the Centres (PZ):

To measure the centres (PZ), do the following:

1. Locate the Cylinder Hole: Identify the hole where the cylinder will be fitted.

2. Measure from the Edge: Measure the distance from the edge of the door to the center of the cylinder hole. This measurement should be 92mm for the Duraflex lock.

3. Confirm Alignment: Ensure that the measurement is consistent on both sides of the door for proper alignment.

Operation of the Lock:

The Duraflex multipoint door lock can be operated in two ways:

1. Lift Lever: To engage the locking mechanism, simply lift the lever handle. This action will activate the latch and deadbolt, securing the door at multiple points.

2. Split Spindle Nightlatch: If using a split spindle, turning the key will engage the lock, while lifting the handle will allow you to operate the latch without unlocking the deadbolt. This feature is particularly useful for added security and convenience.

This comprehensive overview should assist you in understanding the specifications and operation of the Duraflex multipoint door lock gearboxes, ensuring a smooth installation and reliable performance.
