B-LINE SB57412AAL – Frequently Asked Questions
1) What is the Eaton B-Line SB57412AAL, a complete rack or an add-on?
It's an extension kit for an existing two-post open frame network rack, not a standalone rack. The kit supplies uprights, splice bars and 3/8"-16 hardware so you splice added height onto a rack you already have standing. If you need a full freestanding rack, this is the wrong item.
2) How much height does the SB57412AAL add, and how much room do I need overhead?
The kit is stated at 12 inches high, so plan on roughly a foot of added upright above your current rack plus clearance to get the splice bars and bolts in. Check the ceiling, cable tray and sprinkler heads above the rack before you commit, since an open frame extension puts gear right up at that height.
3) What hardware thread size does the B-Line SB57412AAL rack extension kit use?
The splice hardware supplied with the kit is 3/8"-16. That matters on the job because the wrench and any replacement bolts have to match, and it is the thread the splice bars land on when you tie the extension into the existing uprights.
4) What are the footprint dimensions of this B-Line aluminum rack extension kit?
Stated dimensions are 12 x 23 x 24.3125 inches (height, width, length/depth). The 23 inch width and 24-5/16 inch depth line up with a standard two-post open frame footprint, so it is sized to sit on the same centers as the rack it extends rather than widening the aisle.
5) Is the SB57412AAL extension kit steel or aluminum, and will it rust in a damp equipment room?
It's aluminum with a brushed aluminum finish, not painted steel. Aluminum doesn't rust, which is why it gets specified for humid MDF/IDF spaces and coastal facilities. The tradeoff is that aluminum framing carries less load than a comparable steel rack, so heavy UPS and battery gear belongs low in a steel frame rather than up in an extension.
6) What part number do I order for this B-Line two-post rack extension kit?
Order Eaton B-Line SB57412AAL. That part number covers the aluminum extension kit with the uprights, splice bars and 3/8"-16 hardware in brushed aluminum.
7) Will the brushed aluminum finish match my existing B-Line racks?
The finish is brushed aluminum, so it matches other brushed aluminum B-Line open frame racks and will read as a visible difference next to black or grey powder coated frames. If your room is standardized on black racks, this kit will stand out.
8) Is this rack extension kit light enough for one tech to install?
The kit weighs 4.2 lb, so handling it is a non-issue for a single installer. The real constraint is working overhead at the top of a standing rack, which is a two-person job for safety more than for weight.
