B-LINE SB5859090TG – Frequently Asked Questions
1) Will the B-Line SB5859090TG rack take standard 19-inch rack-mount equipment?
Yes. The SB5859090TG is an open frame rack with 12-24 tapped panel mounting holes and 42 mounting spaces, which is the standard rack unit pattern for 19-inch EIA equipment. Overall width is 23 inches, height 90 inches. Because the holes are tapped 12-24, you screw equipment and panels straight to the rails, no cage nuts needed.
2) Is this B-Line rack rated for seismic installation in California?
The SB5859090TG is built as a Seismic Zone 4 rack, which is the highest seismic classification and what specs in California and other high-activity regions call for. It is a closed duct unequal flange design in 11 gauge steel, and it is UL Listed. Seismic performance depends on anchoring it to the slab per the project drawings.
3) How much floor space do I need for a 90 inch B-Line open frame rack?
Footprint works out to 23 inches wide by 90 inches deep, with the frame standing 90 inches tall. Plan aisle clearance on both sides since this is a double sided rack and gear is accessed from front and rear. The rack itself weighs 81.71 lb empty.
4) What does "double sided" mean on this B-Line open rack, and does it come with doors or side panels?
Double sided refers to the rack being open and accessible from both front and back for mounting and cabling. It is an open frame rack, not an enclosure, so there are no doors or side panels. If your application needs a locked, dust-protected enclosure, you want a cabinet rather than this open frame.
5) What is the "closed duct unequal flange" construction on this B-Line rack and why does it matter?
Closed duct unequal flange describes the upright profile: the flanges on either side of the channel are different widths, which gives you a deeper mounting flange on one face and a closed box section for stiffness. In practice that means more rigidity for heavy switch and patch gear in an 11 gauge steel frame, and it pairs with the Seismic Zone 4 rating on this rack.
6) Does this B-Line rack include a top channel for cable runway?
Yes, the SB5859090TG is a top channel style rack, so the top of the frame is set up to tie into overhead ladder rack or cable runway. The runway, standoff kits, and any vertical cable managers are separate items and need to be ordered with the rack.
7) Will a Telco gray B-Line rack match the other racks already in my equipment room?
The SB5859090TG is finished in Telco gray powder coat, the standard telecom equipment room color, so it will sit alongside existing Telco gray B-Line and other telco-finish racks without looking odd. The base metal is steel, powder coated for a durable painted surface in an indoor MDF or IDF room.
