Tile backer board and insulation fixing anchor cob plug dowels are ideal for fixing high performance insulation boards, membranes or lining systems to brick, block or concrete walls. The specially designed dowel is inserted into a pre drilled hole and when the pin is hammered home the base of the fixing dowel expands. These are sometimes called spankers for this reason - you spank it in with a hammer - job done!
100% Anchorage
The expansion grips the substrate to provide excellent anchorage, even in a poor quality base material. Having the fixing dowel expand ensures that your fixings - and your boards or insulation - stays in place.
Ready For Any Job
Different job sizes and fixing methods dictate which expansion fitting is best to use. Use the calculator below to work out what length dowel you need for your project.
