The Side-Pin Heavy Duty Square Jack from Buyers Products features a spring-return drop leg that allows easier expanding and retracting. The spring return is activated by pulling a sturdy side-mounted pin to drop the leg. Ideal for RVs, construction trailers and triaxial trailers, each jack has a 10,000 lb. (dynamic) and 12,000 lb. (static) capacity. The 4 in. square tube features a weather-resistant black powder-coated finish, and includes a footpad. Note: If using dual jacks, use the front pin style of this product.
