In addition to other uses in the utility industry, Blanket Clamp Pins can be effectively used to hold insulating blankets and rubber cover-up in place. Springs are used for tension while extra holes in the body of the pin are used to grip conductors and prevent line hose from sliding. The Salisbury 21 blanket pin has been improved to make it the most versatile pin on the market. Although the 21 pin always opened to accommodate just about any width needed, it has been redesigned to open to a full 5 1/2 inches. That’s the widest of any standard plastic pin in the industry. To accommodate application using a hot stick, the ends of the pin have been tapered to fit into the end of any brand clamp stick. This allows the same 21 pin to be installed in line with the stick.
