For anyone working with plasterboard, cavity walls, or hollow blocks, choosing the right fixing is crucial for strength, durability, and safety. Whether you're a joiner, builder, electrician, plumber, or DIYer, you need reliable, heavy-duty fixing that’s quick and easy to install.
Introducing Zip Fix —a cavity wall anchor that’s strong, non-flammable, and simple to use. Let’s explore why Zip Fix is the ultimate fixing solution.
What is Zip Fix?
Zip Fix is a high-performance cavity fixing designed for plasterboard, cavity walls, hollow concrete blocks, and ceilings. It provides exceptional strength and support and is ideal for lightweight and heavy-duty applications.
Unlike traditional cavity fixings, Zip Fix becomes an all-metal fixing once installed, offering superior fire resistance and durability.
Why Choose Zip Fix?
✔ Rapid Installation – Just Zip & Fix!
Zip Fix is designed for speed and efficiency. With a simple four-step installation, you can securely fix shelves, brackets, radiators, and more in minutes.
✔ Heavy-Duty Performance
Zip Fix provides exceptional strength, handling loads of up to 60kg on certain surfaces. This makes it perfect for professional tradespeople and DIYers alike.
✔ Versatility & Compatibility
Zip Fix is compatible with multiple surfaces, including:
- Plasterboard (drywall)
- Cavity walls
- Hollow concrete blocks
- Ceilings
With one size covering fixture thicknesses up to 45mm, Zip Fix offers unmatched convenience and reliability.
Zip-Fix Load-Bearing Capacity
One of the standout features is its impressive load-bearing capacity. Unlike standard wall plugs that struggle with heavier loads, Zip-Fix provides outstanding strength and support across different wall types.
- 12.5mm Drywall (Single Board) – Supports up to 30kg
- 25mm Double Board (Two Layers of Plasterboard) – Supports up to 47kg
- 15mm Dense Boards (Reinforced or High-Density Plasterboard) – Supports up to 56kg
- Hollow Blocks (Lightweight Concrete Blocks) – Supports up to 60kg
It's strong enough to handle even the heaviest installations, from large TV brackets to heavy-duty shelving units and radiators.
Compared to standard plastic cavity fixings, which typically hold between 5 and 15kg, Zip-Fix provides a significantly stronger and more secure solution.
Why Load-Bearing Strength Matters
Choosing a fixing with the right load-bearing capacity is crucial for safety and longevity. Using weak fixings for heavy installations can lead to loose fixtures, wall damage, or safety hazards. With Zip-Fix, you can trust that your installations are safe, durable, and built to last.
Zip-Fix Installation Guide
Installing Zip-Fix is fast, simple, and requires no specialist tools. Follow these four easy steps:
- Drill a 13mm hole in the wall (ensure at least 50mm cavity clearance behind).
- Insert the Zip-Fix toggle through the hole. Once inside, it will pivot behind the wall to create a secure anchor.
- Zip the nylon collar towards the wall until it sits flush against the surface, then snap off the nylon arms.
- Insert an M6 screw through your fixture and into the threaded part of Zip-Fix, tightening it until secure.

Pro Tips for Installation:
- Ensure you drill the correct hole size (13mm) for a perfect fit.
- If installing in dense boards or hollow blocks, use the longer M6 x 60mm screw for added strength.

Key Features of Zip Fix
Zip-Fix is designed to provide maximum strength, durability, and versatility, making it the go-to fixing solution for both professional tradespeople and DIY enthusiasts. Here’s what makes Zip-Fix stand out from other cavity fixings:
✔ Heavy-Duty Carbon Steel Construction
Unlike plastic or lightweight metal fixings, Zip Fix is made from high-grade carbon steel, ensuring exceptional durability and strength. This means:
- It can handle high loads without bending or breaking, making it ideal for heavy-duty applications.
- No risk of cracking or snapping like plastic fixings, even under heavy loads.
- Suitable for long-term use, ensuring your fixtures remain securely mounted for years.
✔ All-Metal, Non-Flammable – Fire-Resistant to BS 7671 Standards
One of the biggest concerns when choosing fixings is fire safety. Many standard wall fixings, especially plastic ones, melt or fail in high temperatures, increasing fire risks.
Zip-Fix, however, is:
- Fully metal, meaning it won’t melt or degrade in the event of a fire.
- It complies with BS 7671 fire safety standards and is suitable for wiring installations and electrical work.
- Required for fire-rated applications, ensuring that cables, conduit supports, and heavy electrical fittings remain secure even under extreme conditions.
This makes Zip-Fix an excellent choice for electricians, builders, and commercial installations where fire safety is a top priority.
✔ Corrosion-Resistant Zinc Finish – Built to Last
Fixings that are exposed to moisture, air, and different environmental conditions can easily corrode over time, reducing their strength and reliability.
Zip-Fix comes with a high-quality zinc-plated finish, which:
- Prevents rust and corrosion, ensuring a longer lifespan.
- Maintains strength in clean, dry, and low-humidity environments such as homes, offices, and indoor workspaces.
- Reduces the risk of fixings deteriorating over time, giving you peace of mind that your installations remain secure.
✔ Compatible with Multiple Wall Types – Ultimate Versatility
Zip Fix isn’t just limited to plasterboard —it is engineered to work with a wide variety of wall types, making it one of the most versatile cavity fixings available. It can be used on:
- Plasterboard (Drywall) – Single and double-layer boards, ensuring strong and secure fixings.
- Cavity Walls – Providing a firm hold in walls with hollow spaces.
- Hollow Concrete Blocks – They offer a secure fixing even in challenging substrates.
- Ceilings – Ideal for installing light fixtures, ceiling brackets, and more.
This means Zip-Fix can be used in various projects, from home renovations to professional construction jobs. Whether you’re installing shelves, radiators, lighting fixtures, or heavy units, Zip-Fix provides the strength and reliability you need.
👉 With Zip-Fix, you get a high-performance, fire-safe, and long-lasting fixing solution for all your cavity wall needs.
