30in Type IV Ring Buoy
US Coast Guard-approved Type IV 30-in. Ring Buoy. Molded from high-impact, low-density polyethylene, this 30-in. (78-cm) industrial-grade life buoy is built to last, even after repeated exposure to harsh outdoor conditions. The encircling rope attached to the outside of the ring provides an extra non-slip gripping surface and is replaceable, so the buoy can remain on active duty longer.
