B-LINE SB21072BZ – Frequently Asked Questions

1) What does the B-Line SB21072BZ runway splice kit include, or do I need to buy hardware separately?
The SB21072BZ butt-splice kit ships with two clamps and the mounting hardware, so one kit joins one stringer-to-stringer butt joint complete. On a two-stringer cable runway you need two kits per splice point, one for each side rail.
2) Is the B-Line SB21072BZ splice kit UL Listed for an equipment room install?
Yes, the SB21072BZ runway splice is UL Listed. That matters where cable runway is being used as a bonded support system in a data or telecom room and the inspector wants listed components throughout.
3) What is a cable runway butt-splice clamp actually used for?
It joins the ends of two runway stringers end to end so a ladder-style cable runway continues as one continuous run. The SB21072BZ clamps bridge the butt joint and carry the load across it, which is what keeps the two sections from working loose as cable is pulled over them.
4) What material and finish are the B-Line runway splice clamps, and will they hold up indoors over a long run?
The clamps are ASTM A570 steel with a black zinc finish. That is a coated carbon steel plate, suited to interior equipment rooms and matching the black finish commonly used on runway in those spaces. For exterior or wash-down areas you want a hot-dip galvanized or stainless support instead.
5) What size is each B-Line SB21072BZ splice clamp?
Each clamp plate measures 5 in by 2 in by .62 in, and the kit weighs .95 lb total. The 5 in length is what spans the butt joint, so allow clear stringer web on both sides of the joint free of other hardware before you set the clamp.
