The Static Control Anti-Fatigue Mat 9900 Series helps minimize workers' tiredness and control static electricity. The durable rubber mats, which consist of a matrix of hollow cylinders that function like springs when compressed, get softer as compressed, not harder like products made of foam. The black mats weigh 2 lbs. per square foot and come in 3 sizes: 3 ft. x 5 ft.; an octagonal 22 in. diameter; and 3 ft. wide runners that can be cut to a custom length.
