TSS British Standard Retro Fit 5 Lever Upright Mortice Deadlock

£66.00

sku: TSS-3G110

The TSS Retro Fit 5 Lever lock shares the same measurements as the Union 3G110 lock, so it can be used as a direct substitute, but there are a few key differences. Most notably, the TSS lock features a lever design rather than detainers, and it comes with round escutcheons rather than the square escutcheons supplied by Union.

This lock meets the BS3621 : 2007 rating so suitable for insurance requirements.

  • High-Security Protection: Meets British Standard BS3621:2007 with a 20mm deadbolt throw for maximum resistance against forced entry.

  • Easy Upgrade: Designed to match classic upright mortice deadlocks (including Union), making replacement simple and hassle-free.

  • Reliable 5-Lever Locking: Traditional 5-lever mechanism delivers trusted, long-lasting security – supplied with two keys.

  • Versatile & Convenient: Non-handed design fits left or right-handed doors, with round escutcheons included for a clean finish.

  • Perfect for Home & Office: A robust, no-compromise security solution where fire rating or CE/UKCA marking isn’t required.

The TSS Upright Retrofit Mortice Deadlock is designed to match the dimensions of classic upright mortice deadlocks, making it an ideal replacement option.

Unlike detainer locks, this model uses a traditional 5-lever mechanism for secure operation. It shares the same measurements as the Union lock, so it can be used as a direct substitute, but there are a few key differences. Most notably, the TSS lock features a lever design rather than detainers, and it comes with round escutcheons rather than the square escutcheons supplied by Union.

Built in the distinctive upright style, this deadlock complies with British Standard BS3621:2007. To meet this standard, the deadbolt throws at least 20mm from the lock body, providing reliable deadlocking and improved resistance against forced attack.

The TSS Extra Key is a precision-engineered component designed specifically for use with the TSS Retro Fit Deadlock series. These keys serve as vital accessories for property owners needing to expand access for additional users or as a direct replacement for misplaced or worn keys.

Functionality and Use: Each key is machined to exacting standards to ensure a perfect interface with the internal levers or cylinders of the Retro Fit Deadlock. This precision helps to maintain the longevity of the locking mechanism by reducing friction and ensuring a smooth rotation every time the lock is engaged or disengaged.

Typical applications include residential properties where multiple family members require entry, or commercial environments where staff turnover necessitates a reliable supply of additional keys. Because these keys are designed to match the original specifications of the TSS hardware, they provide a higher level of security and reliability than generic blanks.

  • Suitable for both domestic and professional security management
  • Facilitates easy key duplication and management systems
