Lockwood 3772AFSS Selector 3772 MkII Universal Primary Mortice Lock - Aluminium Door Fixing - 60 mm Backset - Satin Stainless Steel
The Lockwood 3772AFSS is a Selector 3772 MkII universal primary mortice lock from the ASSA ABLOY-owned Lockwood Selector 3700 Series, supplied in the Aluminium Door Fixing (AF) build with a 60 mm backset and a Satin Stainless Steel faceplate and strike.
The AF build fits the same heavy-duty Selector 3772 case with a narrow 156 x 25 mm faceplate suited to aluminium-framed commercial doors. It provides secure auxiliary deadlatching, in-door function configuration, and the range's field-selectable escape functions, and it shares the wider 3772 accessory ecosystem (strikes, cams, adaptors, DX conversion and electric-strike faceplates).
The lock body houses a Lockwood 570-series oval cylinder (ordered separately) and is fire tested to AS 1905.1 and rated to AS 4145.2 (Durability D8, Security S7) for demanding commercial and institutional use.
Estimated Warehouse Dispatch: 10-12 business days (special order)

Key Features
- Aluminium Door Fixing (AF) build: narrow 156 x 25 mm faceplate for aluminium-framed commercial doors.
- Universal primary case: field-configured into the full range of Selector escape functions via the correct cylinder cam (X7 or V) and adaptor.
- Auxiliary deadlatching latch bolt: 15 mm stainless steel latch with an anti-thrust deadlatching bolt.
- In-door function selector: red/green selector under the faceplate for simple on-site function setting on MkII cases.
- Non-handed / field reversible: handed on site without disassembly, so one lock covers left and right-hand doors.
- Robust construction: zinc alloy case body on a stainless steel chassis, with a Satin Stainless Steel faceplate.
- 570-series cylinder platform: accepts Lockwood 570 oval cylinders and integrates with Lockwood restricted and master key systems (cylinder ordered separately).

Frequently Asked Questions
It is the same Selector 3772 case supplied with a narrow 156 x 25 mm faceplate sized for aluminium-framed commercial doors. If you already have a timber-faceplate 3772, the 3772-AFKIT converts it to aluminium fixing. For matching your door and stile, see Door Type Matching (Buyers Guide Chapter 04).
No. The 3772AFSS is a lock body only. A Lockwood 570-series oval cylinder and the correct cam (X7 or V) are ordered separately to match your keying system and function - this lets the lock integrate with restricted and master key systems. See how key override works for background.
Yes - the 3772 case is tested to AS 1905.1:2005 (Part 1) for use on fire door assemblies up to 4 hours, in non-holdback configurations. Holdback (H) function builds are not fire door rated. Read what makes a lock fire-door compliant.
Yes. The same 3772 case accepts the 3772-DXKITSC DX digital conversion kit (or the key-override version), or you can step up to the standalone Lockwood Cortex CTX3772 digital lockset.
No - the 3772AFSS is a special-order product and is non-returnable once purchased. Confirm your build, backset, function and finish before ordering; our team can help you check compatibility.
Additional Information
Aluminium doors and stile width. The AF build's narrow 156 x 25 mm faceplate is made for aluminium stiles. Confirm your stile can take a 60 mm backset mortice before ordering - Buyers Guide Chapter 02 - stile width and the measuring your backset how-to cover this.
Cam selection matters. The function you get is determined by the cylinder cam (X7 or V) and the adaptor fitted, not by a different lock body. Confirm the intended function before ordering the cam and cylinder. For a plain-English refresher on the mortice lock format, see the F05 vs F54 mortice locks guide.
Non-handed hosts. The Selector 3772 case is non-handed and reversible on site without disassembly, so one lock covers both left and right-hand doors - see door handing and field-reversibility.
Deadlatching and secondary-lock context. The 3772 latch is auxiliary deadlatching, which resists loiding (slipping the latch). On apartment and strata fire doors this matters for the one-penetration principle - see secondary locks and the one-penetration principle.
Access control and electric strikes. The 3772 is electric-strike compatible via the aluminium 3772AF-2100SS faceplate, so it drops into monitored access-control installations on aluminium doors without changing the mortice pocket.
Accessibility (DDA). As a lock body, the 3772AFSS is not itself DDA compliant - accessibility depends on the lever furniture and door assembly. If your project must meet AS 1428.1, review Buyers Guide Chapter 09 - DDA, NDIS & Accessibility and choose compliant lever furniture accordingly.
Standards, brand and installation. Lockwood is an ASSA ABLOY brand and Australia's most widely specified commercial lock range - see Buyers Guide Chapter 10 - Brand Profiles. For the standards stack (AS 1905.1, AS 4145.2, D and S grades), see Chapter 11 - Australian Standards. Drilling or morticing a fire door carries asbestos and compliance risk in older buildings - read asbestos in apartment fire doors and consider Terry's supply and installation service.
