Unirac 303019M Mill Aluminum Pro-Series Bonding Splice Bar for Pitched Roof

The Unirac 303019M is a Mill Aluminum Pro-Series Bonding Splice Bar engineered for rail-based pitched roof solar mounting systems within the SunFrame product line. Measuring 4-Inch in length x 15/16-Inch in width x 1-1/2-Inch in height, this splice bar joins adjoining rail sections while maintaining continuous electrical bonding across the rail run, a critical requirement for code-compliant grounding on residential and commercial rail-mounted solar installations. Built from mill-finish aluminum, the splice bar is designed to integrate directly with Unirac's Pro-Series rail hardware, providing a mechanically sound and electrically continuous connection point between rail lengths on pitched roof arrays.

Key Features

  • Compact Dimensions: 4-Inch Length x 15/16-Inch Width x 1-1/2-Inch Height for a precise, low-profile fit at rail splice joints.
  • Durable Construction: Mill Aluminum construction offers corrosion resistance and long-term durability suited to outdoor rooftop exposure.
  • Bonding Function: Designed as a bonding splice bar, it maintains electrical continuity across adjoining rail sections, supporting proper system grounding.
  • Rail-Based System Compatibility: Purpose-built for rail-based pitched roof mounting applications within the Unirac SunFrame system.
  • Pro-Series Integration: Part of the Unirac Pro-Series line, engineered to work seamlessly with matching Pro-Series rail and mounting components.
  • Pitched Roof Application: Configured specifically for pitched roof installations, aligning rail sections along sloped rooftop surfaces.

Unirac 303019M – Frequently Asked Questions

1) What does the Unirac 303019M splice bar actually do on a rail run?
The 303019M joins two adjoining Pro-Series rail sections end to end and keeps electrical continuity across that joint, so the rail run stays bonded from one end of the array to the other. It is doing two jobs at once: a mechanical splice and a bonding path. That means you are not adding a separate jumper or lay-in lug at every rail joint to carry the bond across the break.
2) Will the Unirac 303019M work on a flat roof or ballasted solar array?
No. The 303019M is configured for rail-based pitched roof installations within the Unirac SunFrame line. For a flat roof or ballasted system you need the splice hardware matched to that mounting platform, not this one.
3) Can I use the Unirac 303019M with a different brand of solar rail?
It is built to integrate with Unirac Pro-Series rail hardware in the SunFrame system. Splice bars are profile-specific, so a bar cut for Pro-Series rail is not a general fit for another manufacturer's extrusion. Match the splice to the rail you actually have on the roof.
4) What size is the Unirac 303019M bonding splice bar?
It measures 4 inches in length, 15/16 inch in width and 1-1/2 inches in height. That short, low-profile footprint matters at the joint, since the bar seats into the rail at the splice and you do not want it fouling module clamps set near the rail ends. Plan your splice location so clamp positions clear a 4 inch overlap.
5) Do I still need separate grounding lugs if I use bonding splice bars at every rail joint?
The bonding splice bar carries the bond across the rail-to-rail joint, so each splice stays electrically continuous without a jumper. It does not replace the array's connection to the equipment grounding conductor, which still requires a lug or grounding device on the rail. Use the 303019M for continuity between rail lengths and a separate grounding connection to bring the bonded rail run back to the EGC.
6) What is the exact part number to order for the Unirac mill aluminum Pro-Series bonding splice bar?
The manufacturer part number is 303019M. The M on the end is the mill finish. Quote that number with the Pro-Series rail you are ordering so the splice matches the rail profile.
7) Is the 303019M splice bar aluminum or steel, and how does it hold up outdoors?
Mill aluminum. Unfinished aluminum is used here for corrosion resistance on long-term rooftop exposure, and it keeps the splice electrically conductive at the joint, which is the whole point of a bonding bar. There is no paint or coating to scrape off at the contact surface.
8) How many bonding splice bars do I need for a pitched roof rail layout?
One per rail joint. Count every place two rail sections meet in a run and order a splice bar for each, per rail row. A row made from two rail lengths needs one; three lengths needs two. Order a couple of spares, since a splice set on a long run is not somewhere you want to be short mid-install.
