3K70 Non British Standard 5 Lever Mortice Sashlock

Product Overview:

Union 3K70 Mortice Sash Lock

The Union 3K70 mortice sash lock is a robust and reliable choice for securing your doors. As part of the Union C-Series, it mirrors the features of the Union 3G110, originally crafted by Chubb, and now proudly showcases the Union branding.

Key Features:

• Design & Security: This lock boasts a distinctive upright design with detainers instead of levers, providing a high level of security. However, it does not comply with British Standard BS3621:2007.
• Durability: The deadbolt extends 14mm and is equipped with hardened rollers to thwart saw attacks, ensuring enhanced protection.
• Versatile Use: Suitable for doors up to 50mm thick, the lock can be adapted for thicker doors with extra-long keys upon request.
• Handed Locks: Please select the appropriate hand (left or right) based on your door's hinge placement.
• Key Options: Supplied with 2 brass keys, additional keys can be ordered, and locks can be keyed alike for convenience.
• Associated Parts: A range of compatible parts, including key blanks and detainers, are available for purchase.

Installation Notes:

• Ensure your door meets the minimum thickness requirement of 44mm for optimal fitting.
• For new timber doors, consider using Souber’s DBB morticer for efficient installation.

Brand Heritage:

Union has been a trusted name in British lock manufacturing for over 180 years, evolving from a family business in 1840 to a leader in the industry. Their commitment to quality and design ensures that every product enhances the security and convenience of their customers.

Important Considerations:

• Not suitable for fire doors.
• Always check with your insurer regarding lock specifications for residential and commercial properties.
