Latch Deadbolt 2 Hooks 4 Rollers Double Spindle Multipoint Door Lock

Product Overview: Avocet Multipoint Door Lock

The Avocet multipoint door lock is engineered for security and durability, featuring a robust design that includes 4 rollers, 2 hooks, 1 deadbolt, and 1 latch. This lock is available in a sleek Trivalent silver finish, with a stainless steel option available by special order for environments that demand extra resilience.

Sash Lifter Device

Certain Avocet locks included a "sash lifter" device for optimal sash alignment, but these are no longer produced. We recommend replacing these locks with standard versions for better performance.

Backset and Compatibility

Most Avocet locks feature a 35mm backset, with the Affinity Bastion lock designed for composite doors offering a 45mm backset. While older models may have a single spindle and lift lever functionality, current versions are exclusively available in a double spindle nightlatch configuration.

Gearbox Specifications

Avocet gearboxes measure 218mm high, with a backset plus an additional 15mm. The unique cut-out design assists with handle fitment, as screw placements are above the lever. The latch and deadbolt heights are 29mm and 34mm, respectively, with an 82mm distance between them.

Installation and Maintenance

Gearboxes are secured by arms connected with circlips, rather than conventional screws or rivets. Although it is possible to remove a gearbox, we recommend replacing the entire unit for optimal performance. Be aware that the design of the arms has evolved, making older and newer gearboxes incompatible.

Lock Operation

To operate the lock:

• Locking:

  1. Close the door to engage the latch automatically.
  2. Lift the handle to engage the locking points.
  3. Turn the key to secure the system.

• Unlocking:

  1. Turn the key to unlock the system.
  2. Push the handle down to disengage the locking points.
  3. A quarter turn of the key will retract the latch.

Measuring Guidelines

To ensure accurate measurements for your Avocet multipoint door lock, follow these guidelines:

Backset Measurement
To measure the backset, take a ruler and measure the distance from the edge of the door to the center of the lock cylinder. This is crucial for ensuring a proper fit.

Centres PZ Measurement
For the PZ measurement, measure the distance from the center of the keyhole to the center of the handle hole. This will help you select the correct lock configuration.

Faceplate Measurement
To measure the faceplate, determine the width and length of the existing faceplate on your door. This ensures compatibility with the new lock.

By following these steps, you can confidently select the right specifications for your Avocet multipoint door lock, ensuring optimal performance and security.
