Simplest of all drain covers - just remove from its cover, unroll, place it on the drain and the tacky, flexible polyurethane cover forms a tight seal to block out contaminates.
These covers temporarily bond to any smooth surface and are resistant to most chemicals including oils, fuels and solvents. Easily cleaned and reused - just wash with warm soapy water and wrap in plastic sheet.
Three sizes of covers are available, and a vinyl holdall for high visibility storage.
