When you need a versatile jack that can accommodate the needs of a busy FBO, the Alpha Aviation Model 838W Universal Jack is the choice. It provides the strength and stability needed to support larger aircraft, while maintaining the low profile needed to get under smaller low-wing aircrafts. It's a design unique to the Universal Jack series that allows it to easily convert from a 26" low wing jack to a 32" (or 38") standard jack, thus avoiding the high cost of having to purchase a set of model-specific jack. And the 8 ton capacity makes it suitable for lifting just about any General Aviation aircraft with a gross weight of up to 16 tons. The Universal Jacks now come with "Tilt-n-Go" wheels for easy movement. 66 lbs (30Kg) shipping weight.
