B-Line Eaton series open racks, Steel, Flat black powder coa finisht, 39-7/16", Self-supporting relay rack, 11 gauge, ASTM A570

The SB5557096TG self-supporting relay rack stands 96 inches high and 23 inches wide, with a stated length/depth figure of 96 inches. Plan for a 96 inch ceiling clearance plus room above for cable entry and any top channel or ladder rack you tie into. The 23 inch width is the standard footprint for a floor-mounted open frame rack in a telecom or electrical room.

It is a self-supporting relay rack, so it stands on its own base without wall or overhead bracing. Most electrical and telecom inspectors still want the base anchored to the floor slab, and if you are running cable overhead you will typically tie the top channel into ladder rack anyway. But structurally the frame does not depend on that support.

The frame is 11 gauge steel to ASTM A570, which is the heavier of the two common relay rack thicknesses and is what you want for fully loaded equipment columns rather than light patching. The whole rack weighs 93 lb, so it is a two-person set, and the unequal flange open duct design leaves the sides clear for vertical cable management.

Yes, it is a double sided open frame, so you can work and mount from front and back. That is the practical difference between an open relay rack and an enclosed cabinet: no doors, no side panels, full access to terminations from either side. If your install needs locked access or dust protection instead, an open rack is the wrong choice and you want an enclosure.

The SB5557096TG carries a UL Listing. For institutional and MRO buyers standardizing racks across a facility, that is the credential most spec sheets and submittals ask for on a floor-mounted open frame rack.

The unequal flange profile gives you a deeper leg on one face, which opens up duct space alongside the mounting rails for vertical cable runs and tie-off. An equal flange rack has a symmetrical channel and less room to dress cable next to the rails. If you are stacking patch panels with heavy copper or fiber bundles, the unequal flange open duct version keeps the cable out of the equipment depth. For light loads with little cabling, the extra duct space buys you nothing.

Order by manufacturer part number SB5557096TG. That is the 96 inch high, 23 inch wide, 11 gauge self-supporting relay rack from the Eaton B-Line open frame series. Give that number to your distributor rather than describing the height, since B-Line builds several rack heights in the same family.

93 lb empty. That matters twice: once when you carry it up to a mechanical room or a raised floor, and again when you calculate the floor load with equipment added. Two people can set it upright without a lift.
