3 Lift Lever Passive Lock

Product Overview: Millenco Mantis 3 Multipoint Door Lock

The Millenco Mantis 3 multipoint door lock is designed specifically for the passive door in a pair of French doors, featuring no locking points. This version, known as the slave door variant, is equipped with 92mm centres.

Key Features:

• Third Generation Design: The Mantis 3 is part of the third generation of Millenco locks, offering improved measurements of 92mm and 62mm centres (PZ), and is now under the Yale group of companies.
• Variants Available: The Mantis 3 comes in three configurations:
  • 2 hooks and 3 deadbolts
  • 3 hooks and 2 deadbolts with 2 rollers
  • Passive lock version
• Faceplate Options: Historically available with a 20mm faceplate, the Mantis 3 is now exclusively offered with a 16mm faceplate.

Identification Tips:

Identifying a Millenco Mantis 3 lock can be challenging compared to the original Mantis 1 and 2. To confirm you have the correct lock:

• Check the locking points for the unique hook and deadbolt arrangement.
• Measure the centres to ensure they are 92mm/62mm, as early versions may lack branding on the faceplate.

Compatibility:

Earlier Mantis 3 locks had hook positions that differed slightly from modern versions, typically by about 20mm, allowing for compatibility with older models with minimal adjustments.

Gearbox Specifications:

• Configuration: The Mantis 3 gearbox is available in a double spindle for lift lever or double spindle nightlatch operation.
• Backset: The only backset option is 35mm.
• Dimensions: Gearboxes measure 228mm high by 50mm wide. Hookbolt versions include a central hook bolt that throws downwards, measuring 30mm high, alongside a latch of the same height. The distance between the latch and hook is 78mm. The deadbolt version shares these dimensions but replaces the hookbolt with a deadbolt.

Installation Note: Unlike previous Mantis gearboxes, the Mantis 3 gearbox can be easily removed by unscrewing three fixing screws.

Operating Instructions:

1. Lift the handle upwards to engage the locking points.
2. Secure the locking points and main deadbolt (if applicable) by turning the key.

To Unlock the Door:

1. Turn the key to unlock the system.
