Cleaner extends plug life

Cole Hersee Co's Plug Cleaner for seven-pole tractor-trailer plugs extends plug life and improves electrical current flow by cleaning corroded plug contacts in seconds.

The Plug Cleaner cleans with its seven stainless steel wire brushes, spaced to fit into the plug. The ground terminal brush is wider and slightly longer than the other six brushes to ensure an exact fit, guaranteeing a corrosion-free surface. An easy-grip plastic handle is provided, and a snap-on housing covers the brushes. For more information, contact Cole Hersee, 20 Old Colony Ave, Boston MA 02127-2467.
