Lockwood 001 double cylinder deadlatch buying guide
The 001 is Lockwood's double cylinder deadlatch with an open-in strike, sold as either a knob or a lever, in everbrass, brown, matte black, chrome plate and satin chrome pearl.
Open-in strike and double cylinder
An open-in strike lets the door swing inward when unlatched from either side, and needing a key on both sides rather than a turn knob adds a layer of security on a door with a nearby glass panel someone could otherwise reach through.
Knob vs lever
The knob version suits a traditional-styled door, while the lever gives an easier grip and is generally the more accessible option day to day. Browse Lockwood's deadbolts for a simpler single-function alternative, or see door hardware more broadly.
