Reliable hollow wall plugs for gypsum board, chipboard and cavity walls. Designed for secure anchoring in panels and lightweight structures.

What are cavity wall plugs and how do they work?

Cavity wall plugs are specialized fixing elements designed for installation in hollow or low-density substrates such as plasterboard (drywall), OSB, hollow bricks, or chipboard. Their unique anchoring mechanisms – like folding wings or expanding arms – allow for stable and secure mounting even in materials without solid support.

Key advantages of cavity fixings

• Secure fastening in drywall and hollow spaces
• Easy installation without specialized tools
• Even distribution of expansion force
• Versatility across different base materials
• Good resistance to pull-out and deformation

Where are they used?

• Mounting cabinets, shelves, and frames in drywall
• Installing TV brackets, mirrors, and lighting
• Electrical and sanitary installations
• Interior finishing and lightweight structures

Types of cavity plugs

Available options include toggle bolts, metal anchors for plasterboard, plastic expansion plugs with folding arms, and universal fixings. Many variants come with a pre-matched screw or hook for convenience.

What to consider when choosing?

Consider the wall thickness, load requirements, the type of item to be mounted, and the installation method (screw, hook, etc.). For heavy loads, metal cavity anchors or chemical anchors are recommended.

FAQ – Frequently Asked Questions

Which fixings are best for plasterboard?

Plastic or metal cavity plugs such as molly bolts or expanding anchors designed to unfold behind the wall surface are commonly used.

Are cavity wall fixings reliable?

Yes, as long as they are correctly selected and installed according to the application.

Can they be used in OSB boards?

Yes – choose plugs with coarse threads or those designed for increased surface contact.
