Ladder Rack – Heavy Duty Butt Splice Kit

Gruber Heavy-Duty Butt Splice Kit — Black, Seismic-Grade End-to-End Runway Splice

The Gruber Heavy-Duty Butt Splice Kit (Black) is engineered to butt two lengths of cable runway end-to-end in demanding environments, including earthquake / seismic zones. Compared to standard butt splices, this kit uses larger clamp hardware and a more robust clamping footprint to deliver increased mechanical strength and stability where it matters most.

Cable runway drilling is required, allowing the splice plates and heavy hardware to clamp directly to the stringers for a rigid, high-capacity connection. Finished in a durable black coating, this kit integrates cleanly with black ladder rack systems in data centers, telecom rooms, and industrial facilities that must meet stricter structural requirements.

• Heavy-duty end-to-end splice — Joins two runway sections in a straight line for high-load and seismic applications.
• Seismic-ready design — Ideal for use in earthquake-prone areas where additional strength and rigidity are required.
• Requires drilling — Cable runway drilling ensures a secure, through-bolted connection to the stringers.
• Black industrial finish — Matches black ladder rack and provides corrosion resistance in harsh environments.
• Complete hardware kit — Includes heavy-duty splice plates, hex cap screws, nuts, and lock washers.
