Mechanical Insulation Anchor with Plastic Plug and Glass-Filled Nylon Drive Pin

This universal insulation anchor is designed for securely fixing polystyrene and rigid foam insulation boards to concrete, brick, and block substrates. It features a 50mm diameter head with large perforations, providing excellent keying for external wall insulation render systems.

To install, drill a 10mm diameter hole, push the anchor through the insulation, and ensure it is embedded at least 30mm into the base material. Drive in the glass-reinforced nylon pin to create a secure mechanical expansion connection.

Available in two sizes:

• 130mm anchors – suitable for 80–100mm insulation slabs

• 180mm anchors – suitable for 120–150mm insulation boards

Each box contains 250 fixings at unbeatable prices. For mineral wool insulation, use with a 90mm spreading washer.
