Four-post frame racks are ideal for cost-conscious 19-inch rack mount applications. Numbered mounting positions take the guesswork out of installing equipment. Self-squaring design makes assembly a breeze. Mounting depth can be from 24 to 36 inches—great for accommodating deep server chassis. Button holes allow easy, toolless mounting of compatible PDUs and cable managers. Heavy-duty, cold-rolled steel construction ensures years of reliable use.
