OFFboard Shields are vermin restriction devices.  The rat shields are spring-loaded devices created to easily insert on boat mooring lines or overhead utility lines to keep critters such as rats, mice and iguanas away. The OFFboard Rat Shields can be used on lines from 3/8 inch to 2.5 inches in diameter.  The Shields use a spring door that opens and closes on the line allowing easy installation and removal. Once closed, the stainless-steel spring keeps the door closed and in place. The shields are engineered not to damage the line but firmly grip it.

OffBoard Shields are also very effective in keeping rats and mice of your telephone and power lines at your home.  Just measure the diameter of your lines and order either a 10 inch (usually the size for a phone line)
