Keep your feet off of the ice this winter by attaching the X-Series Thermal Floor to your Clam Hub Shelter. This heavy-duty removable floor will help keep your feet dry as well as help keep the heat in your shack. Using Velcro, the floor takes minutes to install, and can be easily removed. These floors have multiple Velcro openings placed throughout so you and your fishing buddies have many options on where to drill your holes. Patent pending.
