Lockwood 3772RSS Selector 3772 MkII Universal Primary Mortice Lock - Full Radius End Faceplate - 60 mm Backset - Satin Stainless Steel
The Lockwood 3772RSS is the Selector 3772 MkII Universal Primary mortice lock supplied with a full radius end faceplate in Satin Stainless Steel and a 60 mm backset. The radius-end faceplate suits doors morticed with a rounded (router-cut) pocket, giving a clean finish without squaring off the mortice.
Built for heavy-duty commercial and institutional use, it is part of Lockwood's Selector 3700 range of commercial-grade cylinder mortice locks. The Selector platform is a "universal" mortice lock: a single case is configured to a range of functions using a red/green function selector under the faceplate, along with interchangeable cams and adaptors.
This listing is for the lock body only. A Lockwood 570-series oval cylinder and cam are not included and are ordered separately to suit your keying system. The lock is rated to AS 4145.2 for lockset durability and has been fire tested to AS 1905.1 on compliant fire door assemblies.
Estimated Warehouse Dispatch: 10-12 Business Days
Key Features
- Universal primary mortice lock body - the versatile core platform of the Selector MkII range.
- Full radius end faceplate in Satin Stainless Steel for a clean finish on router-cut mortices.
- 60 mm backset (standard); 89 mm and 127 mm versions available in related models (4772 / 5772).
- Red/green function selector under the faceplate for simple in-door configuration.
- Anti-lockout and holdback capability (note: holdback configurations are not fire-door rated).
- Improved cylinder functions - lock/unlock and latch retraction included as standard.
- Streamlined cam and adaptor range compared with older systems, simplifying specification and spares.
- Reversible handing - suits left or right hand doors without case disassembly.
- Accepts Lockwood 570-series oval cylinders (cylinder and cam ordered separately).
The Selector 3772 mortice lock has been successfully fire tested for up to 4 hours on compliant fire door assemblies to AS 1905.1:2005. Holdback function configurations (3772V-H, 3772XVH, 3772VTH) are not fire door rated. Fire performance depends on the complete doorset - confirm that hinges, strikes, seals and the door core are all compatible and certified. For a plain-English explanation of Australian fire door and lockset standards, see Chapter 11 - Australian Standards (AS 1905.1), and our guide to fire door types and certification.

Frequently Asked Questions
A full radius end faceplate has rounded ends that match a mortice pocket cut with a router (which leaves rounded corners), rather than a squared-off pocket. Choose the 3772RSS when the door has been prepared with a radiused mortice. If your mortice is square-ended, the standard 3772SS is the match. Finish conversions for radius-end plates use the 3772R-FINKIT.
It has a 60 mm backset. The same lock in an 89 mm or 127 mm backset is catalogued as the 4772 and 5772. If you are unsure how to measure the backset, see our guide to measuring your lock backset and Chapter 02 - Measuring Your Door.
Yes. The Selector 3772 has been fire tested to AS 1905.1:2005 for up to 4 hours on compliant fire door assemblies. Holdback configurations (3772V-H, 3772XVH, 3772VTH) are not fire door rated. Fire performance depends on the whole doorset, so confirm all hardware is compatible. For context, see fire door types and certification and, before drilling any older door, our note on asbestos risk in apartment fire doors.
Yes. A DX Digital Conversion Kit (3772-DXKITSC) adds a mechanical-digital codepad to the existing mortice lock, and the DX with Key Override kit (3772-DXKOKITSC) adds a lower cylinder for key override. For a fully credentialled digital lockset built on the same 3772 body, step up to the Lockwood Cortex CTX3772 digital lockset.
Additional Information
The Selector 3772 is fire tested to AS 1905.1, but a fire-rated lock is only one part of a compliant doorset - confirm hinges, strikes, seals and the door core are all rated and compatible, and remember that holdback configurations are excluded from the fire rating. For a reference list of test certificates see Fire-Rated Certification - Test Reports, and for compliance rules on apartment fire doors see what locks are actually compliant. Fire door and commercial work is a candidate for Terry's professional install - see Site Survey & Installation Services.
The 3772 is a "universal" lock case: function is set by the red/green selector under the faceplate together with the cam and adaptor fitted at installation. The X7 cam retracts the latchbolt and operates the locking bar; the V cam operates the locking bar and retracts the latch after unlocking. MkII adaptors such as the 3770M2-ADAPTOR are not backwards compatible with MkI cases.
This build ships with a full radius end faceplate. For a square-end mortice choose the 3772SS; for aluminium doors use the 3772-AFKIT. When upgrading from an older mortice cut-out - for example an earlier Synergy 3572 - a Securafix retrofit faceplate can cover a wider mortice.
The 3772 is a primary mortice lock. On fire-rated apartment and strata doors, only one penetration of the door leaf is typically permitted, so the primary lock and any secondary lock must be planned together. See our explainer on the one-penetration principle and primary locks.
The 3772 pairs with the Lockwood ES2100 monitored electric strike using the matching ES2100 faceplate kit - 3772-2100SS for timber doors or 3772AF-2100SS for aluminium - to bring the opening into an access-control or monitored system.
