The OTC 5372 3-ton jack stands feature a formed and welded steel base for strength and a self-locking ratchet handle that cannot be released when under load. A durable enamel finish resists corrosion and welded foot pads prevent the stands from sinking into asphalt, gravel or other soft ground. A height range of 12” to 17-11/16” and 11 adjustment positions provides plenty of space while allowing technicians to safely work underneath a vehicle. Every OTC jack stand is ANSI / PALD tested prior to leaving the factory.
