Crain - Extension Tube - 3'

Each extension tube section no. 502 can add up to 4' 8" of length to your stretcher, in 4" increments. Tube holes are punched rather than drilled for accuracy and durability. The spring-loaded buttons are flat on their top side for smooth adjustment. The buttons are precisely located in the inner tube, so they hold the outer tube to the inner tube during transport. Works with other standard diameter poles. Closed length: 2' 10". Useful length adjustment range: 3' 4" to 4' 8".
