Delta Cob Plugs 130mm

Cob plugs are designed for use in substrates where a good fixing point  is hard to acheive therefore the cob plug  is ideal as it  has an expanding stem which provides effective anchorage in a wide range of base materials. Simply drill the 10mm hole, put the plug into the hole and hit the central fixing nail into the plug which causes it to expand into the substrate creating an extremely secure fixing.
