• Strong, durable galvanized steel outer pipe has internal spacing beads to assure a uniform insulating air space between pipe walls
• Each end is die-formed to assure uniform sizing for strong, easy to connect joints
• The double wall (pipe within a pipe) construction with its built-in air space, provides permanent insulation and keeps the inner pipe hot and the outer pipe relatively cool
• This construction creates quick, strong vent action reducing condensation in the pipe and overheating of nearby enclosure surfaces
• Easy to assemble and can be combined to obtain the required installation height
• To calculate installed height, deduct 1-1/2 in for each joint
