The high quality ZTLKA Double Sprung Tubular Latch. This Tubular Latch is a great choice for both Lever Handles or Door Knobs, benefiting from many features such as neat dust-box to conceal chisel marks on the door casing, a secondary removable forend, hardened steel follower, a precion-guided latch-bolt, and heavy dual spring system. All housed in heavy-duty rectangular steel tube for easy fitting.
The term 'double sprung' means the latch has a separate spring for the Latch-bolt (tongue) action, which allows a smooth, soft close to the door. The Tubularl latch features a separate spring for the spindle follower, with a heavy-action return spring to ensure heavy levers are always returned to the horizontal position.
This item is an excellent choice for use with door knobs, as it is available in lengths upto 150mm. We recommend a minimum backset of 82mm or more when using these latches with Door Knobs, to avoid any risk of scraped knuckles on the door frame! Due to this tubular latch's range of features and sizes, the ZTLKA double sprung tubular latch is our recommended latch for most projects.
