The 201 cylinder is a round-format cylinder designed to suit rim locks — the surface-mounted lock cases commonly found on older residential doors, heritage properties, and some commercial applications. Unlike euro cylinders, which drop into a euro profile lockcase, a 201 cylinder mounts directly to the face of the door and operates the rim lock mechanism behind it.
This collection covers four specific variants from Wynns Locksmiths and Lockwood, each suited to a different keying requirement.
The Wynns Round 201 Cylinder (standard, includes 2 keys) is the general-purpose option — available in Satin Chrome, Polished Chrome, and Black Nickel, with keying or master keying available. This is the right choice for most residential and light commercial rim lock applications where you need a reliable, finish-matched cylinder.
The Wynns Gas Industry Keyed 201 Cylinder is keyed to the gas industry standard, making it suitable for gas meter boxes, plant rooms, and utility enclosures that require a standardised key system. Available in Satin Chrome and Polished Chrome.
The Wynns Fire Industry Keyed 201 Cylinder (003) is keyed to the fire industry 003 standard — used on fire hose reel cabinets, fire indicator panels, and other fire services infrastructure where emergency services need guaranteed key access. Available in Satin Chrome and Polished Chrome.
The Lockwood 201 Power Industry Cylinder is keyed to the power industry standard, used on electrical switchboards, substations, and utility infrastructure. Available in Satin Chrome and Polished Chrome.
