B-LINE SB5557084TG – Frequently Asked Questions
1) How tall is the B-Line SB5557084TG relay rack, and how much floor space does it need?
The SB5557084TG self-supporting relay rack stands 84 inches tall and measures 23 inches wide. Plan on roughly two feet of wall width plus working clearance front and back, since it is an open frame with no side panels. It weighs 87 pounds bare, so account for that plus equipment load on the floor.
2) Does this B-Line relay rack need to be bolted to a wall or ceiling?
No. The SB5557084TG is a self-supporting relay rack, so it stands on its own floor footprint rather than hanging off wall angle or ceiling bracing. Most electrical and telecom installs still anchor the base to the floor for seismic or code reasons, but structurally the frame carries itself.
3) Is this an open frame rack or an enclosed cabinet?
Open frame. The SB5557084TG is an open duct unequal flange rack, which means exposed uprights and open sides rather than a sealed enclosure with doors. That gives you free air movement around gear and easy cable access from both sides, but no dust protection and no lockable security. If you need equipment locked away, you want an enclosed cabinet instead.
4) What does unequal flange mean on this B-Line rack, and why would I choose it?
Unequal flange describes the upright profile: one leg of the channel is deeper than the other, which creates a built-in vertical cable duct alongside the mounting rail. That is why it is catalogued as an open duct rack. Installers pick this profile when they want vertical cable management integrated into the upright instead of bolting separate duct to the side of a standard equal-flange relay rack.
5) What gauge steel is the B-Line SB5557084TG made from?
The uprights are 11 gauge steel to ASTM A570, which is the hot-rolled carbon steel sheet spec. That is the heavier end of relay rack construction and is what lets the frame carry loaded equipment over a full 84 inch height without added bracing.
6) Can I mount equipment on both sides of this relay rack?
Yes. The SB5557084TG is a double sided frame, so it is set up for access and mounting from front and back. Leave rear clearance when you lay out the room, otherwise you lose half the usable access.
7) Is the B-Line SB5557084TG UL Listed for an electrical room install?
Yes, the rack carries a UL Listed marking, which is typically what an inspector or facility spec calls for on rack and frame hardware going into an electrical or communications room.
8) Does this rack come with a top channel for cable runway?
Yes, the SB5557084TG is a top channel style frame, so the top of the rack is built to tie into overhead cable runway or ladder rack rather than terminating in a bare upright. That matters if you are running horizontal tray across the room and need a landing point on each bay.
9) What color is the SB5557084TG rack finished in?
Telco gray powder coat. If you are adding to an existing lineup of racks in a telecom or MDF room, that is the common gray used across telco frames, so it lines up visually with neighboring bays rather than standing out the way a black or white rack would.
10) What part number do I order for this 84 inch B-Line telco gray relay rack?
Order Eaton B-Line part number SB5557084TG. That is the 84 inch self-supporting open duct unequal flange relay rack in telco gray powder coat.
