Our lowest capacity 700 series jibs utilize precision aluminum ZRA1 rail for a lightweight, easy moving boom up to 20 ft (6 m) long with 220 degree rotation. The boom features a running surface with less than 1% rolling resistance and is anodized for a smooth, clean, corrosive-free surface. For custom jibs, low profile jibs, or portable pallet base mounts, consult the factory. Air and electric supply packages are sold separately. Stud anchors or bolts are to be supplied by the customer.
