B-Line Eaton series runway splice, Heavy duty cable runway butt-splice clamp and kit, ASTM A570 structural steel, Finish yellow zinc

The SB168C2YZ is a butt-splice clamp kit for joining two lengths of cable runway (ladder rack) end to end, so the stringers meet in line rather than overlapping. It is sold as a clamp and kit, so the fasteners for the splice come with it. Use it where a runway run continues straight through a junction and you need the two sections mechanically tied together.

Yes, the SB168C2YZ carries a UL Listing. That matters on institutional and government jobs where the drawings call for listed support components on the cable pathway, and it is the line an inspector will look for on a submittal.

Yellow zinc plated ASTM A570 structural steel is a plated indoor finish. It suits conditioned spaces like data centers, telecom rooms and equipment closets. For exterior, wet or corrosive locations you want a hot dip galvanized or stainless splice hardware instead, since plating alone is not an outdoor finish.

No. It ships as a clamp and kit, so the splice hardware is included in the part. Order one kit per joint you are splicing; a long runway run needs one at each butt joint on the run.

A butt splice keeps the two runway sections in the same plane and at the same elevation, which is what you want for a continuous straight run and a clean cable transition. An overlap or angle splice stacks one stringer on the other and shifts the elevation slightly, so it is better where you are changing height or tying into a wall angle bracket. For a flush inline joint, the SB168C2YZ butt-splice kit is the right type.

Eaton B-Line part number SB168C2YZ. The SB168C2 identifies the butt-splice clamp kit and the YZ suffix is the yellow zinc finish. That is the number to quote when matching existing splices on a runway system already installed.
