Latch Deadbolt 2 Hooks 2 Rollers Double Spindle Multipoint Door Lock (top roller to spindle = 730mm) - Shootbolt Compatible

This Avocet multipoint door lock is designed for durability and security, featuring a robust configuration that includes:

• 2 Rollers
• 2 Hooks
• 1 Deadbolt
• 1 Latch

Recognized for its unique locking positions, this lock is often referred to as the yellow version. It's important to distinguish it from the silver AVO352H2RSS, which has different roller positions.

Once removed from the door, Avocet multipoint locks are easily identifiable. The faceplates typically bear the Avocet logo, although older models may display the "WMS" logo. The uniquely shaped gearboxes feature a cut-out that extends below the latch, aiding in the identification of multipoint locks.

Originally, Avocet multipoint locks were available in various configurations, including hooks, rollers, and deadbolts. The earlier models were made from yellow passivated steel, giving them a distinctive brassy appearance. Recent iterations have transitioned to faceplates crafted from stainless steel or a Trivalent silver finish.

As the locks evolved from yellow passivated to silver, many variations were phased out. Notable exceptions include the 2 roller and 2 mushroom lock, as well as a shorter version of the 3 deadbolt lock designed for caravans. If you need assistance finding suitable replacements for these locks, please reach out to us.

Some Avocet multipoint door locks also feature a "sash lifter" device, which was intended to ensure proper alignment between the sash and frame. However, since these devices are no longer available, we recommend replacing locks with the standard version.

Most Avocet locks are designed with a 35mm backset, while the Affinity Bastion lock is tailored for composite doors, featuring a 45mm backset.

Although some original Avocet multipoint 4 roller door locks have a single spindle and lift lever functionality, all current models are available only in a double spindle nightlatch configuration. The centres are positioned at 62mm and 92mm, but if nightlatch functionality is unnecessary, the lock can still function as a lift lever version using the top spindle.

Locks designed for PVCu with a flat 16mm faceplate can accommodate shootbolts.

Avocet gearboxes measure 218mm high plus the backset (add 15mm). The large cut-out in the top corner, extending below the latch, is a distinctive feature that aids in handle fitment, as the screws are positioned above the lever.

The gearboxes include a latch measuring 29mm high and a deadbolt at 34mm high, with an 82mm distance between the top of the deadbolt and the bottom of the latch.

These gearboxes are secured to the strip using arms connected by circlips, rather than conventional screws or rivets. While it is possible to remove a gearbox from a complete Avocet lock, we recommend replacing the entire unit. Note that the design of the arms has evolved; older gearboxes feature a flat clip, while newer versions have a slightly curved connecting arm, making swaps between old and new versions impossible.

When measuring the backset, remember to allow 2-3mm for the faceplate. Thus, a 35mm backset gearbox will measure 32mm when not attached to the strip.

Avocet hooks operate in opposing directions, with the top hook moving upwards and the bottom hook downwards. Hook boxes are 123mm high, and doors typically prepared to 150mm will accommodate the hook case.

Avocet deadbolts feature a 20mm throw made from nickel-plated brass, with a distinctive chamfered design that contrasts with the square design of Avocet hook cases.

Rollers, also made from nickel-plated brass, serve to compress and pull the door against the frame, helping to prevent dust and water ingress. While they do not significantly enhance security, they assist in preventing door warping by providing support across the full height, contingent on the rollers being engaged in their keeps.
