> What are the dimensions of B-Line B101 and B104 strut corner angles?

- Category: Hardware › Framing
- Kind: Standard part
- Basis: Distributor listings of B-Line catalog numbers; the B-Line section prints leg and hole drawings that could not be read here, so numbers only, no file
- Page: https://xemstudio.com/objects/strut-angle-fittings/ · JSON: https://xemstudio.com/api/geometry?object=strut-angle-fittings · Plain text: https://xemstudio.com/objects/strut-angle-fittings/sheet.txt

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- The listings give one length, the width, a depth and the hole count, not each leg's length or which holes sit on which leg, so no file is drawn (it would mean inventing the layout). Hole 9/16 in; 1-7/8 in spacing and 13/16 in from an end are the general fitting numbers.
- Gusseted angles are not listed here: gusset dimensions were not available.
