Leg Boots

Mesa ETP Leg Boots (Floating Roof Support Leg Socks) are designed to reduce emissions and product loss caused by vapors escaping from floating roof support legs. Mesa ETP Leg Boots are designed with innovative MesaThane 6036 urethane seal material to form a covering for the support legs. (Mesalon 7010 is available for ethanol applications). The Leg Sock provides excellent chemical resistance against products in the tank while resisting the harshest environmental conditions outside the tank. The Leg Sock ID is determined by the roof support leg handle type, pin length and leg sleeve OD. Mesa ETP designs Leg Socks according to specifications stated on the data sheet, which is completed by the customer. In addition to emission reduction, Mesa ETP Leg Boots helps prevent corrosion by preventing rainwater from entering and collecting in the floating roof support leg. This is an additional benefit to the tank owner, and an exclusive feature of Mesa ETP Leg Boots.
