Lockwood 8654 vs Whitco Tasman MK2: Dimensional & Retrofit Comparison

When evaluating lockwood 8654 vs whitco tasman mk2 for an existing hinged aluminium or stainless-mesh security screen door, the great news for DIY renovators and locksmiths is that both locks are manufactured under the ASSA ABLOY Australia umbrella to fit the standard Australian 19mm wide by 195mm high rectangular mortice cut-out in a 20mm to 25mm thick aluminium door stile. However, their external furniture plates, internal snib geometry, and latch mechanisms differ in three practical ways:

1. Escutcheon Plate Width & Paint Footprint Coverage: The Whitco Tasman MK2 features a wider sculpted zinc-alloy furniture plate (238mm high x 34mm wide) that excels at covering weathered paint shadows and old rivet holes when upgrading 1990s or 2000s colonial cast-aluminium doors. The Lockwood 8654 uses a sleeker contemporary architectural plate (240mm high x 28mm wide) with an anti-jemmy serrated bevelled edge engineered for modern Amplimesh and Crimsafe-style security doors.

2. Internal Privacy Snib & Deadlocking Action: On the Lockwood 8654, flicking the internal snib lever engages immediate day-latch privacy, while turning the key deadlocks the internal snib so an intruder cannot reach through pet mesh to flick the lever open. On the Whitco Tasman MK2, the oversized ergonomic thumb-turn snib provides light, arthritis-friendly operation and non-handed reversible latch bolt rotation in seconds.

3. Austral Yarra Ridge & Elegance Cross-Compatibility: If your existing security door is fitted with an Austral Yarra Ridge or Elegance hinged lock, verify the horizontal spindle-to-cylinder screw spacing: Austral hinged locks also drop into a standard 19mm x 195mm stile cut-out and connect to standard 3-point auxiliary rod kits.

19mm x 195mm Frame Cut-Out, Backset & 3-Point Rod Kit Checklist

Before ordering any hinged or sliding security screen lock from our Security Screen Door Locks category, grab a tape measure and confirm four measurements on your door edge: (1) rectangular mortice body slot height (standard 195mm) and width (19mm); (2) horizontal backset from the outer edge of the aluminium stile to the centre of the cylinder keyhole (typically 13mm to 15mm on flush stiles); (3) vertical fixing screw centres (175mm between top and bottom through-screws); and (4) whether your door uses a single-point centre latch or a 3-point triple-lock cable/rod actuator that throws top and bottom shoot bolts into the header and sill.

Why Security Doors Require a Lazy Cam Euro Cylinder

One of the most frequent mistakes DIY installers make when fitting a body-only screen door lock is purchasing a standard fixed-cam commercial Euro barrel instead of a dedicated lazy cam euro cylinder. In a hinged or sliding security screen door lock, the internal privacy snib and the external key barrel actuate the same internal locking slider. A 62mm single-piece screen door barrel (such as our Carbine TES5, Carbine CPL, or Lenlok LPL series in Door Lock Cylinders) is built with rotational free-play ("lazy cam" motion) so the cam lobe rests out of the way when the key is withdrawn, allowing your family to flick the inside privacy snib open and closed all day without jamming against the barrel. Even better, because our Carbine and Lenlok screen door cylinders use the standard Australian C4 5-pin brass keyway, you can add our Custom Keyed Alike Service (SKU: KA) so your security screen door, front deadbolt, and entrance handle all work on one matching house key.

How to Replace Lock on Sliding Door (Patio Glass & Screen Sliders)

When you need to replace lock on sliding door assemblies on an aluminium rear patio or balcony, start by identifying whether the lock is a surface-mounted chassis (bolted to the face of the aluminium extrusion) or a narrow mortice hook lock recessed inside the stile. For surface-mounted patio locks, measure the exact distance in millimetres between the two main vertical mounting screws (most Australian patio doors manufactured over the last 30 years use 82mm, 107mm, or 128mm screw centres). Remove the two internal handle machine screws while supporting the outer pull handle, slide the spindle and snib tailpiece out cleanly, and transfer the new gasket and chassis onto the existing holes without redrilling the tempered glass frame.

Whitco Blaxland Patio Lock vs Lockwood Onyx Sliding Door Lock

Choosing between a whitco blaxland patio lock and a Lockwood Onyx sliding patio door lock comes down to your existing screw hole centres and beak engagement style. The Whitco Blaxland series is Australia's most versatile retrofit patio lock, available in 82mm and 128mm fixing centres across Black, White, and Primrose powdercoat finishes with single-beak or twin-beak anti-lift hooks and C4 cylinder options. The Lockwood Onyx series offers an ergonomic wrap-around D-handle with twin-jaw opposed locking hooks tested to Standards Australia AS 4145.2 physical security benchmarks and a visual red/green lock status indicator. Both models are stocked in our Sliding & Cavity Door Locks collection for 24-48hr Victorian warehouse dispatch.

Frequently Asked Questions

Q1: In the lockwood 8654 vs whitco tasman mk2 comparison, are the 3-point rod kits interchangeable?
Both locks fit the same 19mm x 195mm door stile cut-out and 175mm screw centres, and both connect to standard ASSA ABLOY / Whitco 3-point auxiliary rod kits. However, if you are swapping from a Tasman MK2 to an 8654 on an existing 3-point door, always check the internal drive-bar clip orientation before removing the old rods.

Q2: Why does my new security screen door lock come without a cylinder ("No Cylinder / Body Only")?
Many trade packs of the Whitco Tasman MK2 and Lockwood 8654 are sold "Body Only" so you can choose between a standard 5-pin C4 lazy-cam cylinder, a double-cylinder keyed-alike pair, or your existing reusable 62mm Euro barrel.

Q3: Can I book a mobile locksmith in Melbourne to replace my screen or patio door lock on-site?
Yes. If your aluminium door frame needs re-riveting, roller carriage adjustment, or 3-point rod alignment across Metropolitan Melbourne or Regional Victoria, contact our service team at All Secure Locksmiths on (03) 9306 6760 or 0421 149 760.
