Tripp Lite SmartRack Rear Support Rail Kit for Select 1U ATS PDUs Mounted in 4-Post Racks and Rack Enclosures

Overview

The Tripp Lite PDU4PKIT is a rear support rail kit designed specifically for select 1U Automatic Transfer Switch (ATS) Power Distribution Units (PDUs) mounted in EIA standard 4-post racks or enclosures. It addresses the common issue of chassis sagging caused by heavy input plugs and power cables pulling on the back of the PDU. By reinforcing the rear of the unit, this kit ensures the PDU remains level and securely positioned, maintaining the integrity of your power infrastructure.

The kit includes two rail assemblies that telescope from 22.8 to 36 inches, allowing easy adaptation to various rack depths. Its sliding design enables precise positioning and mounting without the need to remove other equipment, making installation efficient and less disruptive.

Key features

• Provides rear support to prevent sagging of select 1U ATS PDUs caused by heavy cables and plugs
• Adjustable rail assemblies fit rack depths ranging from 22.8 to 36 inches for versatile installation
• Rails attach securely to both the PDU and any EIA standard 4-post rack or enclosure
• Includes front rail sections and mounting screws for straightforward assembly
• Rear rail sections fasten to the rack using user-supplied cage nuts and screws, allowing compatibility with existing hardware
• Sliding rail design enables one-person installation without disturbing other rack equipment, saving time and reducing risk of damage

Key specs

Installation and setup

The kit’s design allows the front rail sections to fasten directly to the PDU using the included screws, while the rear sections attach to the rack with cage nuts and screws you provide. The telescoping rails slide to accommodate different rack depths, enabling you to position the PDU precisely and align mounting holes without removing other devices. This streamlined process supports quick, one-person installation, ideal for busy data centers or edge cabinets where minimizing downtime is critical.

Ideal uses and environments

This rear support rail kit is well suited for data center technicians, network administrators, and field service personnel who manage power distribution in dense rack environments. It works effectively in server rooms, network closets, and edge computing setups where heavy power cables can strain PDU chassis. By stabilizing the PDU, it helps maintain reliable power delivery and protects valuable equipment from mechanical stress.
