Designed for the safe transport of industrial and commercial use compressed gas cylinders, these storage carts store cylinders from 4- to 12-in (102- to 305-mm) in diameter back-to-back. Constructed from 7- and 11-gauge (5- and 3-mm) steel, each unit includes upper and lower brackets to provide added support and securement locations for cylinders. Offset deck design, reinforced with three sets of support bars for strength and rigidity, makes cylinder loading easy and safe at only 1.75-in (45-mm)
