For easy, out-of-the-way fan mounting options, this aluminum side bar connects the front of the fan cage to the back with room for two fans and is a great choice to keep your animals cool. At shows where rear fans are not allowed, side fans are the perfect solution. For easy mounting, one end of the bar telescopes to easily secure into place. Two T-knobs tighten on the arm to reduce rattling and C-clamps hook around the cage for added stability and safety. Measures 4-1/2″ W x 93-1/4″ L x 3-3/4″ H and weighs 8.66 lbs.
