Wykamol Plaster Membrane Plugs are high quality fixing plugs which can be used to fix and secure our wide range of Damp Proof Membranes to the wall / substrate. Wykamol Plaster Membrane Plugs are supplied without Sealing Washers. If a seal is required then use Wykamol Ultimate Plaster Membrane Plugs instead. An 8mm SDS Drill Bit is normally required for fixing Wykamol Plaster Membrane Plugs, however a 7mm Bit may be used in 'poorer' substrates. Supplied in (W) 8mm x (L) 65mm size only. Available in Pack Sizes of 100 or 200 Fixings.
