This Avantis multipoint door lock features 2 Rollers, 2 Hooks, 1 Deadbolt & 1 Latch.

The Avantis 550 Series French door lock is easily recognised by it's unique latch and deadbolt configuration.

Avantis locks have the largest hooks on the market at 25mm.

This is the standard version but a narrow locking position version is also available.

Avantis multipoint door locks are one of the easiest locks to identify before you have removed it from the door. They feature an unusual configuration where the deadbolt sits above the latch.

Avantis locks are specifically designed for the UK residential door market. They feature a 25mm throw and a direct drive deadbolt in the main gearbox whereas most gearbox deadbolts from other manufacturers only throw 20mm. The Avantis deadbolt also features 5 grooves and is chamfered for improved compression.

Also, 16mm faceplate locks are compatible with shootbolts.

Established in 2006, Avantis is a relatively new multipoint lock manufacturer, so demand for repairs and replacements is beginning to grow. The business was established by the former CEO of Millenco, so while the brand is new, there is plenty of expertise available in the UK market.

Avantis gearboxes are unique in the market, featuring a distinctive grooved deadbolt sitting above the latch. The deadbolt measures 30mm high and extends 25mm when thrown. The distance from the bottom of the deadbolt to the top of the latch is 60mm and the latch is 24mm high.

These gearboxes are available as a double spindle with centres at 92mm and 62mm. Therefore, they can be used with a double spindle nightlatch functionality (often used on front doors) or as a standard lift lever, using the top spindle only (commonly used on back doors). The spindles feature a unique cross shape but they also accept a normal 8mm spindle.

Gearboxes measure 220mm high x backset +15mm. Be sure to allow for 2mm when measuring the backset on a lock that already has the faceplate fitted.

Gearboxes are fixed to the faceplate using 4 screws. One is above the deadbolt, with 2 screws between the latch and deadbolt and the last screw is located below the latch. They measure 47mm from the top to the 2nd screw hole, 40mm from the 2nd to 3rd and 42mm from the 3rd to 4th screw hole.

Avantis are proud to state their hooks are the largest on the UK market and provide the highest level of security. They are chamfered to ensure that the door is pulled to the frame, to enhance weather sealing. Also, hooks on Avantis locks throw in opposing directions.

Rollers are used for compression, to pull the door against the frame, to help prevent dust or water ingress. They do little for security, but they also have the added benefit of helping to prevent the door from becoming warped as it is supported across its full height. This is dependent on the rollers being engaged into their keeps.
