Key Features and Benefits
- Converts compatible Eclipse enclosures into EIA-310 rack mounting systems by supporting HLPUR rack rails for networking, industrial automation, communications, and control equipment.
- Supports three rack mounting positions including vertical, angled, or facing the enclosure door, allowing equipment placement to be optimized for accessibility and cable routing.
- Compatible exclusively with HLPUR rack rails (sold separately), allowing you to select the rack unit height that best fits your application.
- Mounts directly to the factory panel studs at the rear of compatible Eclipse enclosures, simplifying installation with no enclosure modifications required.
- Can be installed with or without an interior mounting panel, allowing electrical controls and 19-inch rack equipment to share the same enclosure. This makes it ideal for converged OT and IT applications.
- Maintains the enclosure's UL, CSA, and NEMA ratings when field installed according to Hammond recommendations.
- Finished in a durable RAL 9005 black powder coat for long-lasting corrosion resistance.
- Manufactured in North America for dependable quality and availability.
- TAA-compliant, manufactured in North America within an ISO 9001 certified facility.
- RoHS and REACH compliant.
The ERP Series Rack Rail Mounting Panel adds industry-standard 19-inch rack mounting capability to Hammond Eclipse enclosures. Designed to work with HLPUR rack rails, it allows installers to mount switches, patch panels, industrial computers, communications equipment, and other rack-mounted devices while preserving the enclosure's environmental protection.
Unlike traditional rack enclosures, the ERP Series can be installed over an existing interior panel, allowing electrical controls and rack-mounted data equipment to coexist within the same enclosure. With support for vertical, angled, or door-facing equipment positions, it provides exceptional flexibility for industrial networking, automation, and edge computing applications.
When Another Product May Be a Better Choice
- When you need rear service access to rack-mounted equipment, consider our ESF Series Swing-Out Rack Frame.
- When you need a complete industrial rack enclosure, consider our NWC Series Type 12 Rack Cabinet or NWM Series Type 4 Rack Cabinet.
Example Buying Guide:
HLP8UFR
Note that if you are not using the vertical rack-mounting, you can fit more than one fixed rail in an enclosure.
