**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## Notes

- Designation 087F125-MM: 087 = 0.875 in (7/8) depth, F = furring (hat) channel, 125 = 1-1/4 in face, MM = minimum thickness in mils; 150F125 is the 1-1/2 in deep version. Flanges are 1/2 in (CEMCO). Sold to ASTM C645 / AISI S220 (nonstructural).
- Drawn with vertical webs and out-to-out legs (overall width 2-1/4 in less 2t). Real rolls flare the webs slightly, so the drawn areas run about 1.5 to 2 % under SFIA's published gross areas (087F125-43: 0.165 drawn, 0.168 published; 150F125-43: 0.221 vs 0.225). The flare angle is not published.
- Inside radius per the SFIA thickness table. Cross-section shown as a 200 mm length; no knurled face, no hemmed legs (ClarkDietrich sells a 25 ga hemmed-leg version).
- A metric omega-profile table (EN 14195) was not found in a free source and is not included.
