Tripp Lite Butt-Splice Kit for Straight and 90-Degree Ladder Runway Sections, Hardware Included

The Tripp Lite SRLBUTTSPLICE is a butt-splice kit that joins two ladder runway sections so cabling can continue along a single, solid pathway. By locking adjoining rails together, it prevents sagging and misalignment that could strain cables or complicate future moves, adds, and changes.

This kit works with straight runs as well as 90-degree turns, so you can extend a ladder in a direct line or pivot it around an obstacle without switching hardware. It matches both solid and tubular steel runways with a 1.5- by 0.375-inch profile and is fully compatible with SmartRack ladder systems already in place.

All mounting hardware arrives in the box, letting installers finish the splice with basic hand tools and no extra trips to the parts bin. A data center technician can bridge two runway sections over a row of racks, while an IT manager in a smaller wiring closet can create a tidy corner turn above an open frame rack. In each case, the splice keeps cables supported and accessible, helping maintain proper bend radius and airflow.

The steel components hold up under daily wear, vibration, and the occasional on-site adjustment, making this a long-term solution rather than a temporary fix. If your cable pathways need to grow or change direction, this kit offers a straightforward way to keep everything secure and organized.

Highlights:

• Connects two ladder runway sections for a continuous cable pathway
• Supports both straight extensions and 90-degree turns
• Compatible with SmartRack ladder systems in data centers and server rooms
• Fits solid or tubular steel runways that measure 1.5 x 0.375 inches
• Includes all mounting hardware for quick, tool-based installation
