B-LINE SB21042YZ – Frequently Asked Questions

1) How much room do I need to fit a B-Line SB21042YZ corner kit in a cable tray run?
Plan for a 14.75 by 14.75 inch footprint with a 2 inch height. That is the clearance the corner assembly occupies at the turn, so check ceiling grid, sprinkler lines, and adjacent racks before you commit to the corner location.
2) What size hardware does the B-Line corner support kit use, and will it match my existing runway bolts?
It uses 3/8-16 hardware, which is the same thread size used across Eaton B-Line runway hardware, so your wrench set and any spare fasteners on the job carry over. The 3/8-16 bolts and the clamp are supplied with the kit.
3) What steel and finish is the B-Line 90 degree runway corner kit made from?
Yellow zinc plated ASTM A570 structural steel. A570 is a hot rolled carbon sheet and strip steel used for structural sections, and the yellow zinc plating is a standard indoor corrosion finish, so this kit is intended for dry interior runs such as telecom rooms and data halls rather than exposed outdoor or wet locations.
4) Do I need a separate splice kit to turn a corner in a B-Line cable runway?
Not with this part. The SB21042YZ handles the 90 degree change of direction as a single kit, since the runway section, the clamp, and the 3/8-16 fasteners are all included. You order one kit per corner in the run.
5) What part number do I quote for the B-Line yellow zinc 90 degree runway corner kit?
Order it as Eaton B-Line SB21042YZ. The YZ suffix is the yellow zinc finish, matching other yellow zinc B-Line runway components on the same run.
6) How heavy is one B-Line corner support kit for overhead install planning?
Each kit weighs 3.5 lb, light enough for a single installer to set on a ladder, but if you are hanging a long run with several corners add that into your threaded rod and anchor load calculation.
