AutomationDirect: Penn-Union Split Bolts, Power Bars, Service Post Connectors, and More

March 3, 2026

AutomationDirect now stocks split bolt connectors, power bars, service post connectors and mechanical connector oxide inhibitors from Penn-Union.

Penn-Union split bolt connectors deliver a secure, long‑lasting connection for two conductors in a wide range of power distribution applications. With options engineered to handle multiple wire gauges and material combinations—including CU‑CU, CU‑AL, and AL‑AL—they offer the flexibility installers need on every job. 

Aluminum, black pre-insulated power bars and in‑line splicers/reducers are engineered to handle two to four conductors in AL‑AL, AL‑CU, or CU‑CU configurations. Designed for broad compatibility and with a rugged construction and dependable insulation, these connectors provide a clean, reliable solution for modern power distribution needs. 

Bronze service post connectors deliver outstanding conductivity thanks to their premium high‑copper wrought alloy construction. Built for versatility and long‑lasting reliability, these connectors create a solid, dependable link between copper cables and steel structures, bus bars, transformers, or electrical enclosures.

Mechanical connector oxide inhibitors are specially formulated to block oxidation and corrosion before they start—ensuring long‑term performance and reliability. They’re essential when working with aluminum or any combination of dissimilar metals, creating a cleaner, more stable connection that keeps your system running at peak efficiency.

New Penn-Union mechanical connectors start at $2.25 (S-10-1)  oxide inhibitors start at $15.00 (1/2PT10CUALGEL-1)
