Strut Cross-Reference: Unistrut, B-Line, PowerStrut & More
Strut grew out of one part-number system, so the major brands are largely interchangeable: a channel nut, clamp, or fitting built to the standard 1-5/8" profile fits another brand's channel of the same size. If you have a Unistrut, B-Line, PowerStrut, SuperStrut, Erico, PHD, or Haydon part number, the table below gives the Eugene Fastener equivalent. Have a number that is not listed? Send it to us and we will match it.
How Strut Cross-Referencing Works
Most strut manufacturers use parallel numbering that traces back to the original Unistrut catalog (P-numbers like P1010 for a channel nut, P1000 for standard channel). Because the parts are dimensionally standardized at 1-5/8", equivalents interchange. Note that finishes differ by number in some brands (plain vs galvanized vs stainless); the cross-references below are for the standard electro-galvanized version unless noted. Always confirm finish and size for your application.

Frequently Asked Questions
Are Unistrut and other strut brands interchangeable?
Yes, at the same profile. Strut channel and accessories built to the standard 1-5/8 inch profile interchange across Unistrut, B-Line, PowerStrut, SuperStrut, and others. A channel nut or fitting from one brand fits another brand's channel of the same size, which is why a cross-reference works.
How do I find the Eugene Fastener equivalent of a Unistrut part?
Look up the Unistrut number in the tables above, or send us the number and we will match it. For example, Unistrut P1010 (a 1/2-13 regular spring channel nut) is our STR4124. We cross-reference the full line across all the major brands.
Do the cross-references account for finish?
The numbers shown are for the standard electro-galvanized version unless noted. Some brands use different numbers for plain, galvanized, and stainless finishes. Tell us the finish you need and we will confirm the exact equivalent.
What if my part number is not in the table?
This page shows the most-requested parts; we carry and cross-reference far more. Send us any Unistrut, B-Line, PowerStrut, SuperStrut, Erico, PHD, or Haydon number and we will identify the Eugene Fastener equivalent.
