Omega Bottle Jack with an in-line design and 20-ton capacity features a lift height from 9-1/2" to 18-5/8". Omega Hydraulic Bottle Jacks are designed to be used vertically for lifting, but not sustaining, loads based on the rated capacity of the jack, not including trailers, houses, or other building structures. This easy-to-use, accessible pumping system eliminates off-center pumping force for the most efficient operation, and the unit's hydraulic system is protected from over-pumping damage by a patented, built-in by-pass mechanism. A serrated, heat-treated saddle provides a generous lifting area and secure grip, and the heat-treated extension screw allows for low pick-up height adjustment and maximum lift height. A unique, cross-type forged release valve assures positive control, and an extra large, rugged base provides stability and strength. Critical stress points are reinforced in all models for added durability and dependability.
