Camco's Black Boar Snow Plow Marker Kit helps you easily see the edges of your plow. The highly visible florescent orange color provides enhanced visibility in harsh conditions. These tubes work with the Black Boar Snow Plow (Camco # 66016). Each tube measures 18-inches from top to bolt with a 1/2-inch OD. Includes (2) tubes and mounting hardware. The flexible marker tubes are constructed of high-density polyethylene and are capped with a piece of flexible vinyl. The ends that mount to the snow plow each have a stainless steel threaded hose barbed fitting with a zinc-plated steel washer and nut.
