ENERGY GUARD™ provides a superior perimeter seal along the sides and rear of your dock leveler and blocks dirt, debris, insects and most importantly prevents energy loss. The innovative design closes off the gaps between the dock leveler and concrete pit walls - typically missed by traditional weather seal or under-leveler seals attached to the front of the dock leveler. ENERGY GUARD prevents the mass flow of air, minimizing the transfer of heat and energy into and out of the facility.
