Zanda Vertex Lever Handle – Knurled Square Profile | Astron Range

Zanda Vertex Door Lever Handle from the Astron range. Knurled square profile lever, 25mm width. 53mm round rose. Available in passage, integrated privacy, separate privacy, dummy and entrance configurations. Works with Adaptor Kits 10063 and 10064 for retrofitting over existing holes. Available in four finishes.

Why Choose the Zanda Vertex Lever?

The Vertex brings a tactile knurled texture to a square-profile lever body — a combination that sits firmly in the premium contemporary category. At 25mm wide with a 53mm rose, the proportions are refined and intentional. The square lever profile reads as architectural against timber and glass doors alike. Adaptor kits 10063 and 10064 make retrofitting straightforward — no need to re-bore or patch existing holes. Four finishes covering the most in-demand tones in current Australian residential and commercial specification.

Frequently Asked Questions
What is a knurled square profile lever and how does it look and feel?

The Vertex has a square lever body with a knurled texture — a fine cross-hatched pattern machined into the lever surface that provides grip and a distinctive tactile quality. The square profile gives the lever a sharper, more architectural edge compared to round bar levers, while the knurling adds depth that catches light differently throughout the day. At 25mm wide, the lever body is substantial without being heavy — a proportion that reads as considered and premium in person. It is one of the most distinctive lever profiles currently specified in contemporary Australian interiors.

What configurations is the Vertex Lever available in?

The Vertex is available in five configurations: Passage (10031) — free passage with no locking for hallways and living areas; Integrated Privacy (10032) — privacy button built into the lever set for bathrooms and ensuites; Separate Privacy (10036) — privacy bolt as a standalone component; Dummy (10033.D) — fixed non-functional lever for wardrobes and inactive doors; and Entrance (10034) — keyed entry for residential and commercial entry doors.

What are the Adaptor Kits 10063 and 10064 and do I need one?

Adaptor kits allow the Vertex to be installed over existing bore holes that are larger or differently positioned than the standard 53mm rose would cover — making the Vertex an ideal choice for renovation and retrofit projects where re-boring or patching is not practical. 10063 and 10064 cover different rose sizes and configurations — confirm which adaptor kit suits your existing door setup before ordering. If you are installing on a new door with a standard bore, an adaptor kit is not required. Contact our team on 1800 329 028 to confirm compatibility.

What is the difference between Integrated Privacy and Separate Privacy?

Integrated Privacy (10032) has the privacy locking button built directly into the lever set — everything installs as one unit. Separate Privacy (10036) supplies the privacy bolt as a standalone component, which is useful for retrofit installations where a bolt already exists, or where the bolt needs to be positioned at a different height on the door. For new builds, integrated privacy is the cleaner and simpler installation. For renovation work, separate privacy offers more flexibility. If unsure, contact our team on 1800 329 028.

What finishes is the Vertex Lever available in?

The Vertex is available in four finishes: Brushed Nickel / Polished Chrome (BN/CP) — a versatile dual-tone that reads warm in some light and cool in others; Graphite Nickel (GN) — a dark metallic tone that bridges brushed nickel and matt black; Matt Black (BLK) — bold and contemporary, suited to industrial, Japandi, and minimalist interiors; and Satin Brass (SB) — warm golden tone popular in contemporary, Hamptons, and transitional homes. All four finishes are available across all five configurations.

How does the Vertex compare to other Astron range levers?

The Vertex is the square knurled profile option within the Astron range — a more geometric and tactile choice compared to smooth round-bar or curved lever profiles in the same range. If you prefer a round bar profile with knurling, the Zanda Wyatt offers a similar texture in a round form. If you want a smooth square profile without knurling, other Astron levers provide that option. The Vertex is the right choice when you want the combination of sharp geometry and tactile grip in one handle. Visit our showroom to compare profiles side by side before specifying.

Yes — Prime Hardware stocks 6,000+ products on display at our showroom at 2/249 Annangrove Road, Annangrove Sydney 2156.
