The Stella Cavity Fixing is a high-performance universal anchor designed to provide maximum grip in both plasterboard and solid walls. It is an advanced alternative to standard wall plugs, offering increased holding power and durability.

Unlike basic fixings that only work on specific surfaces, the Stella Fix is highly versatile and can be used on:

✔ Plasterboard (single and double layers)
✔ Concrete & solid block walls
✔ Hollow concrete & cavity walls
✔ Cheshire clay brick & engineering brick
✔ Stone & wooden panels

The unique expansion mechanism allows Stella Fix to contract into a star-shaped knot behind the plasterboard, providing maximum grip and even load distribution. This ensures a secure hold, even in fragile materials like drywall and cavity walls.

The Black Stella Cavity Fixing is stronger and longer, explicitly designed for double-layer plasterboard, which is often used in partition walls, soundproofing applications, and fire-resistant walls. If you’re working with thicker walls, this is the fixing you need.

• Length: 59mm – engineered for 25mm double-layer plasterboard.
• Maximum Load Capacity: 41 kg – can handle heavier loads such as large cabinets, radiators, and heavy-duty brackets.

If you're unsure which one you need, simply check the thickness of your plasterboard. If it's 12.5mm, go for Red; if it's 25mm, go for Black.

✔ Strengthened nylon plug Provides extra durability and prevents cracking.

✔ Corrosion-resistant metal components – Ensures longevity in various environments.

Installing Stella Cavity Fixing is quick, simple, and requires no specialist tools. Follow these steps:

Use a 10mm drill bit to make a hole in the plasterboard or solid surface.

Firmly push the Stella Fix plug into the hole until it sits flush with the surface.
