B-LINE SB166A2BZ EXT CLAMP – Frequently Asked Questions
1) What is the Eaton B-Line SB166A2BZ runway splice clamp used for?
The SB166A2BZ is a butt-splice clamp and kit for cable runway. It joins two runway stringers end to end so a straight run can be continued past the length of a single stringer. It is a splice hardware kit, not a wall or ceiling support, so you still need your own standoff brackets or threaded rod supports at the splice point.
2) Is the B-Line SB166A2BZ cable runway splice UL Listed?
Yes, the SB166A2BZ splice clamp is UL Listed. For institutional and MRO specs that call for listed support hardware on grounded cable runway systems, that listing is the line item inspectors look for.
3) Do I order one B-Line splice clamp per runway joint or two?
Cable runway has two stringers, one on each side of the run, and this is sold as a single clamp and kit under model SB166A2BZ. A full butt splice across the runway therefore takes one kit per stringer, so count two per joint and multiply by the number of joints in the run.
4) What material and finish is the B-Line runway butt-splice clamp, and will it hold up in a data center or telecom room?
It is ASTM A570 structural steel with a black zinc finish. That combination is built for dry indoor conditions, which covers most equipment rooms, MDF/IDF closets and data centers where black cable runway is standard. The black finish also matches the typical black runway stringer so the splice does not stand out mid-run. For wet or corrosive outdoor exposure, black zinc is not the finish you want.
5) Will this splice clamp work for a corner or a tee in my cable runway?
No. This is a butt-splice clamp, meant for joining two stringers in line, end to end. Turns, tees and elevation changes in a runway system need the corresponding junction or radius hardware from the runway line, not a butt splice.
