PermaSEAL Cob Plugs 130mm

Expanding Stem Cob Plugs - 130mm

PermaSEAL Cob plugs are designed for securing membranes in substrates where a good fixing point is hard to achieve. The cob plug is ideal as it has an expanding stem which provides effective anchorage in a wide range of base materials.

Using Cob Plugs

Simply drill the 10mm hole, put the plug into the hole and hit the central fixing nail into the plug. This causes it to expand into the substrate creating an extremely secure fixing.
