Iver — For the Design-Conscious Renovator
Iver is the brand we recommend most often to homeowners who are doing a renovation and want hardware that genuinely elevates the look of the space — not just fills a functional need.
Launched in 2021 but backed by nearly 40 years of industry experience through Southern Design Group, Iver was designed from the ground up with a single goal: make premium architectural hardware accessible without the premium-only price tag. The result is a range that sits comfortably in both architect-specified new builds and weekend renovation projects.
What makes Iver stand out:
Every lever, knob, and pull handle in the Iver range is made from solid forged brass. This matters because forged brass is denser, heavier, and more durable than cast or hollow alloy — it's the difference between hardware that feels substantial in your hand and hardware that feels like it came from a flat-pack box. Every product in the range is also fire rated to AS1530.4:2014 for 2 hours, making Iver a smart choice for anyone building or renovating to code.
The finish range is one of the broadest available in this segment: Brushed Brass, Polished Brass, Signature Brass, Brushed Chrome, Polished Chrome, Satin Nickel, Polished Nickel, Distressed Nickel, and Matt Black. And because Iver is a whole-of-home collection — spanning door handles, pull handles, cabinet hardware, and more — you can achieve a genuinely cohesive look from the front door to the pantry.
Iver warranty: Iver covers defects in materials and workmanship on door furniture (levers, knobs, pull handles, locks, and latches), with warranty terms varying by product and finish. Select finishes — including Polished Chrome, Brushed Chrome, Polished Nickel, Distressed Nickel, and Brushed Gold PVD — carry specific finish warranties. The Brushed Gold PVD finish carries a lifetime guarantee against defects under normal residential use. For specific warranty information, check the individual product listing or ask our team.
Iver is perfect for: Renovators who want design-led hardware that feels as good as it looks. Custom home builders. Interior designers specifying across a full project. Anyone upgrading from builder-grade hardware who wants a noticeable step up in quality and aesthetics.

Gainsborough — For Everyday Reliability Across the Whole Home
Gainsborough is one of the most recognised names in Australian door hardware — and for good reason. Founded in Melbourne in 1967 and now part of the global Allegion group, Gainsborough has over 50 years of product development behind it. Chances are you've used a Gainsborough handle at some point without even knowing it.
Gainsborough's strength is breadth and reliability. Their range covers everything from simple passage levers to smart digital locks, deadbolts, and screen door hardware — all under one brand, all designed to work together. For a homeowner who wants consistent, well-priced hardware throughout a property without spending hours specifying multiple brands, Gainsborough is the natural default.
What makes Gainsborough stand out:
Gainsborough is Australian-designed and built with the local market in mind. Their ranges are developed to suit standard Australian door dimensions and conditions, and their product line includes options for everything from the simplest internal door through to smart lock front door solutions. The Gainsborough Trilock — a three-in-one deadlocking lever — is one of the most popular front door solutions in Australian residential builds for good reason.
Gainsborough warranty: Gainsborough's warranty varies by range and finish, covering 7, 10, or 15 years on mechanical components and 2, 5, or 10 years on finish, depending on which product you choose. This warranty is handled through the point of sale — keep your proof of purchase. For most residential ranges, you're looking at solid mid-range warranty coverage that reflects the brand's confidence in their products.
Gainsborough is perfect for: Homeowners fitting out an entire property who want a reliable, well-supported Australian brand at a sensible price point. Volume builders. Rental and investment properties. Anyone who wants smart lock capability without changing their whole hardware approach.

Lockwood — For Security, Longevity, and Matching Existing Hardware
Lockwood is Australia's most established security hardware brand — part of the ASSA ABLOY family, the world's largest lock manufacturer. If you've ever lived in an Australian home built in the last four decades, there's a strong chance it had at least one Lockwood product on a door somewhere.
Where Lockwood truly differentiates itself is on two fronts: security engineering and warranty. Their products are developed and tested to a standard that reflects their heritage in both residential and commercial security — not just aesthetic hardware.
What makes Lockwood stand out:
Lockwood's mechanical warranty is the strongest in this comparison at 25 years — a genuine statement of confidence in the longevity of their hardware. Their range is designed in Australia specifically for Australian conditions and door standards, and spans everything from simple rose lever sets to high-security entrance lock combinations, deadbolts, and cavity pulls.
If you already have Lockwood hardware throughout a property and need to match it — for a renovation, an extension, or a replacement — Lockwood's consistent design language across their ranges makes it easier to co-ordinate than many other brands. Their Vivid and Velocity series in particular offer strong finish consistency across levers, hinges, flush pulls, and door stops.
Lockwood warranty: Lockwood offers a 25-year mechanical warranty on workmanship and materials across their door hardware range — the longest mechanical warranty of any brand in this comparison. This is backed by ASSA ABLOY's Australian warranty and consumer law guarantees.
Lockwood is perfect for: Anyone prioritising security above all else. Homeowners matching or extending existing Lockwood installations. Properties where longevity and long-term warranty support are the primary concerns. Commercial applications where hardware will see heavy daily use.
Nidus — For Statement Style and Contemporary Design
Nidus is the newest brand in this comparison and one that has rapidly built a strong following among interior designers, custom home builders, and renovators looking for something with a distinctive personality. Now operating as Nidus by Carbine, the brand combines its signature design aesthetic with the engineering backing of one of Australia's most respected security hardware manufacturers.
The Nidus range draws heavily on European — particularly Mediterranean and Italian — design traditions, resulting in hardware that has a tactile, artisanal feel that's quite different from the clean minimalism of most Australian hardware brands. Their Domici and Marino lever designs, and their knurled handle range in particular, have become go-to specification choices for architects and designers working on high-end residential projects.
What makes Nidus stand out:
Beyond the aesthetics, Nidus is a serious hardware brand. Their Mediterranean range is built for both residential and commercial interiors, and their newer ranges extend into stainless steel for external and high-traffic applications. The brand also serves as the official Australian importer for Manital, a premium Italian door hardware collection that adds an additional tier of European craftsmanship to their offering.
Nidus warranty: Nidus offers a 10-year mechanical warranty and a 5-year finish warranty across their range — strong coverage that reflects the brand's confidence in their manufacturing quality and finish durability.
Nidus is perfect for: Homeowners and designers who want hardware with a distinctive design identity rather than a neutral background presence. Custom homes, luxury renovations, boutique commercial spaces. Anyone drawn to Mediterranean, Italian, or textured design aesthetics.
So Which Brand Should You Choose?
Here's how our locksmiths would summarise it:
Choose Iver if you're renovating and want premium solid brass hardware with genuine design credentials, a broad finish range, and the ability to co-ordinate across your whole home — including cabinet hardware.
Choose Gainsborough if you're fitting out a whole property and want a trusted, widely supported Australian brand with strong warranty coverage across a full range of door and security hardware at a sensible price point.
Choose Lockwood if security is your primary concern, you're matching existing Lockwood hardware, or you simply want the longest mechanical warranty available and hardware designed and tested to Australian security standards.
Choose Nidus if you want door handles that make a design statement — hardware with personality, tactile detail, and a European design sensibility that stands out in a high-end renovation or custom build.
