The 1850S-220-628 from Adams Rite is a Deadlock with Short Throw and 31/32″ Backset in Clear Anodized.

It features a 360-degree turn of the key or thumb turn to throw or retract the counterbalanced bolt, ensuring the key can only be removed when the bolt is securely locked or unlocked. The cylinder must have an MS dimensioned cam.
