Avocet Pioneer 3 Deadbolt Double Spindle Multipoint Door Lock – Caravan Lock
Quick ViewDoor Locks, Multipoint, Multipoint & UPVCAvocet Pioneer 3 Deadbolt Double Spindle Multipoint Door Lock – Caravan Lock
0 out of 5(0)This Avocet multipoint door lock features 3 Deadbolts & 1 Latch.
Avocet multipoint door locks are easily identifiable once they are removed from the door. Faceplates are usually stamped with the Avocet logo, although older locks may have the “WMS” logo stamped. Gearboxes are uniquely shaped, with the cut out extending below the latch, which is unique when identifying multipoint locks.
Avocet multipoint door locks were originally available in a wide range of different configurations featuring hooks, rollers, deadbolts and an Affinity Bastion lock with opposing hooks. Earlier versions of Avocet multipoint locks were made in yellow passivated steel, which have a distinctive brassy colour. Recently, the locks have changed with faceplates made from a stainless steel or a Trivalent silver finish.
When these locks swapped from yellow passivated to silver, the majority of variations were replaced. Notable exceptions include the 2 roller and 2 mushroom lock as well as the shorter version of the 3 deadbolt lock designed for use on caravans. Please contact us if you would like assistance finding the best replacements for these locks.
Also, it’s worth noting some Avocet multipoint door locks feature a “sash lifter” device. This device was designed to help ensure the correct sash to frame alignment but these are no longer available so we would recommend replacing these locks with the standard version.
Most Avocet locks are only available in a 35mm backset, but the Affinity Bastion lock is designed for composite doors and feature a 45mm backset.
Although some original Avocet multipoint 4 roller door locks feature a single spindle and lift lever functionality, all current locks are only available in a double spindle nightlatch configuration. The centres are at 62mm and 92mm, but if the nightlatch functionality is not required, the lock can still be used as a lift lever version using the top spindle.
All Avocet locks which are designed for PVCu with a flat 16mm faceplate have the ability to accept shootbolts.
Avocet gearboxes measure 218mm high x backset + 15mm. It’s the large cut out in the top corner, that extends below the latch which makes them unique. This feature can assist with the fitment of handles as the screws are located above the lever.
Avocet gearboxes feature a latch that is 29mm high and a deadbolt that is 34mm high with a distance of 82mm between the top of the deadbolt and the bottom of the latch.
These gearboxes are not attached to the strip using conventional screws or rivets. Instead, the gearboxes are held by arms which connect using circlips. While it’s possible to remove a gearbox from a full Avocet lock, we would advise replacing the full unit. Also, it’s worth noting the design of the arms have changed over time and older gearboxes have a flat clip. Newer versions have a slightly curved connecting arm located lower down making gearbox swaps with newer for older versions impossible.
When measuring the backset, allow 2-3mm for the faceplate, so a 35mm backset gearbox will measure 32mm when not fixed to the strip.
Avocet deadbolts feature a 20mm throw made from nickel plated brass. The deadbolt gearboxes feature a distinctive chamfered design, in contrast to the square design of Avocet hook cases.
