Large Clay Plug Drain Cover - Double

Plug rugs are flexible mats consisting of a putty like layer of clay based composition, reinforced with hessian and with a peel-off plastic backing. Laid over drains, storm sewer inlets or around pipe runs, plug rugs will seal off and prevent a spill entering the drains, even on uneven surfaces. They can also be used for blocking large holes or rips in tankers and will even form a seal when fuel or chemicals are already flowing over the surface. Designed for single use..
