Engineered for low-clearance applications, the B&B SUMNER Lo Heavy Duty Pro-Jack delivers the same durability and features as its Hi counterpart but with a reduced working height of 20 – 37″ / 508 – 940 mm. It holds pipe diameters up to 12″ / 300 mm and supports a load of 2,500 lbs / 1,135 kg. A V-head ensures secure placement and compatibility with multiple optional heads. Its rigid steel frame includes reinforced legs and a 1.5″ ACME adjustment rod, complemented by a quick-lock washer for swift and secure height modifications. Shipping weight is 18.00 lbs / 8.00 kg, making it lightweight yet rugged enough for fabrication, workshop, or field use.
