The Andersen Company No. 4403 Comfort Flow Anti-Fatigue Linkable End Mat is static-dissipative with a high density, closed cell nitrile rubber cushion that is made from 15% recycled content. This lightweight, flexible mat has beveled edges for safe transitioning from mat to floor and a lifetime anti-microbial treatment to prevent odors and degradation of the mat. The Comfort Flow anti-fatigue mat is certified slip-resistant by the National Floor Safety Institute and features drainage holes that allow liquids to flow through the mat. This mat is welding safe, chemical resistant, and grease & oil proof making it recommended for many kitchen and industrial applications. Unlike the original comfort flow anti-fatigue mat, this style is linkable and allows the user to connect and remove pieces to fit into the work area. This piece is an end piece, which has borders on three sides and links on one.
