This is a high quality  Double Sprung Tubular Latch.  The term 'Double Sprung' means the latch can be operated both left and right - ie. A door knob can be turned either way to retract the latch.

This item is excellent for use with door knobs, incorporating the double sprung feature and available in lengths upto 150mm. (We recommend a minimum backset of 57mm or more when using these latches with Door Knobs to avoid any risk of scraped knuckles on the door frame!)

Specific Dead Bolts are available to match this product- see related products below.

Supplied in singles complete with screws, strike plate and dust box.
