This British Standard TSS mortice sash lock has been designed with the same dimensions as classic mortice sash locks with a 40mm backset.
These BS3621 mortice sash locks meet the requirements of British Standard BS3621:2007. To meet this standard, products undergo rigorous testing. Featuring 5 levers, anti drill and anti saw features, these are a high quality and high security mortice lock.
These locks feature a blue lock case but they have unique measurements that identify them from other mortice locks. While the case width features standard 67mm (2.5″”) and 79mm (3″”) sizes, the backset measures just 40mm on the 67mm width case and 53mm on the 79mm width case. Please refer to the line drawing for details.
To meet the requirements of British Standard BS3621, the deadbolt throws at least 20mm from the body of the lock to ensure positive deadlocking and additional resistance against attack. The deadbolt also has anti saw features.
