Lockwood 001 Sleeve Installation Video * Now Available * 

Have not tested it with the 335 yet, 002 is ok

Yes, a night-latch type lock, latch lock, in place of a deadbolt

ahmadaamer6 it’s just a dead locking latching unit it’s more used here to replace existing nightlatchs to add better security and stop carding the door. You would not on a normal day go replace a deadlock with one in my opinion.

@@NzTechNinja Cool. Thanks for the info.

Lockwood 001 is suitable for unit doors, and some people want to change from one to the other

A 001 is far superior product to most deadbolts.
