Gas cylinder mobile stands are portable storage stands for the safe transport of compressed gas. Suitable for over-the-road gas-cylinder transportation, these mobile stands accommodate cylinders from 4- to 10-in (102- to 254-mm). Fully welded construction using 11-gauge (3-mm) steel provides structural integrity while the locking collar and post system adds a vise-like holding capability to immobilize the cylinder. Use the safety cylinder caps to ensure DOT compliance. The locking post extends up to 66-in (1677-mm) in height.
