B-LINE SB57412ATG – Frequently Asked Questions
1) What is the Eaton B-Line SB57412ATG open rack kit actually for?
SB57412ATG is a two-post network rack extension kit from the Eaton B-Line open frame rack series. It is not a complete standalone rack. The kit supplies uprights, splice bars and 3/8"-16 hardware so you can add height to an existing two-post open frame rack rather than replace it.
2) What hardware comes with the B-Line SB57412ATG rack extension kit?
You get the uprights, the splice bars that join the extension to the existing rack, and 3/8"-16 hardware. Nothing else is included, so any additional mounting hardware for the equipment itself is a separate order.
3) How much height does the SB57412ATG extension kit add to a two-post rack?
The kit measures 12 inches in height, with a 23 inch width and 24.3125 inch depth. Check the clearance above your existing rack before ordering, since you need that full 12 inches plus room to work the splice bars.
4) Can I use the SB57412ATG kit on a four-post or enclosed cabinet rack?
No. It is a two-post extension kit built around splice bars that tie into two-post open frame uprights. A four-post rack or an enclosed cabinet needs its own matching extension or frame components, not this kit.
5) Is the B-Line SB57412ATG extension kit steel or aluminum, and will it match my existing gray racks?
Aluminum construction with a Telco gray powder coat, which is the standard finish on Eaton B-Line open frame racks. If your existing frames are the same Telco gray B-Line series, the extension will match visually. Aluminum keeps the added weight low at 4.2 lb for the kit.
6) What thread size are the bolts on the B-Line two-post rack extension kit?
The kit ships with 3/8"-16 hardware. If you are pulling spare bolts from stock for the splice joints, match that thread, not the 12-24 or 10-32 sizes used for mounting equipment to the rack rails.
7) Does the B-Line SB57412ATG rack extension kit come in other finishes or sizes?
It is sold as a single configuration, model SB57412ATG: aluminum, Telco gray powder coat, 12 inch height. There is no finish or height choice to specify on this kit.
