Description
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 precision-guided latch-bolt, and heavy dual spring system. All housed in a heavy-duty rectangular steel tube for easy fitting.
The term double sprung tubular latch means the latch has a separate spring for the Latch-bolt (tongue) action, which allows a smooth, soft close to the door. The Tubular 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.
The double sprung tubular latch is an excellent choice for use with door-knobs, as it is available in lengths up to 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. For more information on how to choose the correct tubular latch, and get the right size for your door, please see our handy guide on Tubular Latches right here.

Noticeable improvement in operation over standard latches. Nicely finished and designed with plastic covers to hide screws in the cutouts and reversible latch direction to fit all handles.

Really solid latch, good positive spring.

The mechanism and operation is 5* but the casing is slightly taller than the previous standard one, and the mounting plate with 2 screw holes has a longer end which is rounded and also it protrudes further because seemingly unnecessary bends have been put in what should be a flat plate

Is the tubular latch easy to reverse (so can be used on left or right hand doors)?
These are very easy to have reversed, all you need to do is turn the brass lounge round so its facing the way you need it.

Hi there
We have some unsprung internal door knobs so we need a sprung latch. I’m looking for a latch that is suitable for lower mobility, the ones we have are too difficult. These double sprung ones look good, but have you any alternatives or suggestions? The knobs will remain, just want to swap the mechanism. Thank you
Hi Jenny,
From what you have described this latch will be perfect for you.
