The Ransom Master Mat provides a firm, yet cushioned surface for working on all kinds of precision parts and assemblies. The ribbed edge contains spilled fluids and prevents small parts from rolling off the mat. Ribbed compartments are molded into the top area of the mat so small parts can be placed safely away from the main work area. The Master Mat is resistant to most gun cleaners, paints, varnishes, ect. To clean, just wash with solvent or soap and water. Measures 19" x 11-3/8". Note: Do not use MEK, Acetone or lacquer thinners, as these types of solvents may soften the work surface.
