This stand is one-half of the Park Tool Deluxe Double Arm Repair Stand (PRS-2 OS), and incorporates most of the same features in a stand suitable for smaller areas. The 100-3c clamp rotates 360 degrees and is adjustable for virtually any size frame tubing up to 1-5/8" (41mm). Clamp height is now adjustable from 50" to 62" (127-158cm) utilizing larger diameter tubing and a 68 lb. base to ensure a rigid working station. The PRS-3OS is heavily chrome plated and is also available without the base. Base dimensions are nominally 22.5-inches by 22.5-inches by one-half inch thick.
