B-LINE SB166ABZ – Frequently Asked Questions
1) What does the B-Line SB166ABZ butt-splice clamp actually do in a cable runway installation?
The SB166ABZ is a butt-splice clamp kit that joins two runway stringers end to end, so you can run a continuous ladder rack down a data room or telecom space without the stringers relying on a rack or wall support at the joint. It is sold as a clamp and kit, so the fasteners that make up the splice come with it.
2) Is the B-Line SB166ABZ runway splice UL Listed for a telecom or data center job?
Yes, the SB166ABZ splice kit is UL Listed, which is usually what an institutional or facilities spec asks for on cable runway hardware in a communications room.
3) What size is the B-Line SB166ABZ splice clamp and how much does it weigh?
The splice measures 5 x 1.5 x .62 inches and weighs .48 lb. That .62 inch dimension is the thin one, so it sits tight against the stringer web rather than eating clearance in the runway channel.
4) What material and finish is the B-Line runway butt-splice clamp, and will it hold up indoors?
It is ASTM A570 structural steel with a black zinc finish. A570 is a hot-rolled carbon structural steel, so the clamp carries load rather than just locating the joint, and black zinc gives a matte dark finish that matches typical black cable runway in a data or telecom room. Black zinc is an indoor-duty plating, not a marine or outdoor coating.
5) Do I need a rack or wall bracket at the point where two runway stringers meet if I use this splice?
A butt-splice clamp is what makes the joint itself, connecting stringer to stringer directly, so the splice does not have to land on a support. Support spacing is still set by your runway manufacturer's load and span guidance for the run as a whole. The SB166ABZ ships as a clamp and kit for that stringer to stringer connection.
6) What part number do I order for the Eaton B-Line black zinc runway splice?
Order it as B-Line SB166ABZ. That single model covers the black zinc version of the butt-splice clamp kit.
