1/4 Stainless Steel Clamp For clamping cable or tubing securely into place, especially in harsh environments. Smooth "coined" clamp edges prevent damage to cable insulation. Constructed from corrosion resistant 304 stainless steel. Insulated parts are constructed from 304 stainless steel and coated with polyolefin, a thermoplastic co-polymer that provides a durable non-toxic, odorless coating that has very good low temperature flexibility and excellent electrical properties. This coating also has FDA food contact approval.
