Product Overview
The IronRidge Diagonal Brace Hardware kit (GM-DB-HW01-M1) holds the bolts, set screws, washers and nuts that fasten a diagonal brace to its two sleeves on an IronRidge Ground Mount. IronRidge lists one kit for both 2" and 3" pipe.
IronRidge Ground Mount combines XR100 or XR1000 rails with locally sourced 2" or 3" steel pipe or mechanical tubing. Vertical pipes (piers) are set in concrete or ground screws, and horizontal pipes run across their tops. A diagonal brace runs at an angle between a north and a south leg to stiffen the structure.
The brace tube and sleeves are sold separately. The set screws lock each sleeve to its leg, and the bolts join the brace to the sleeves.
Best For
- Completing a diagonal brace: IronRidge's cut sheet shows one hardware kit, one brace tube and two sleeves per brace.
- 2" or 3" pipe ground mounts: IronRidge lists this kit "For 2” & 3” Pipe".

Important Considerations
- Install order. IronRidge's manual says to install diagonal braces before the top caps.
- Sleeve placement. IronRidge says to place the north sleeve 2–3" above the ground (6" max) and the south sleeve 2–3" below the top cap (6" max), then raise the south sleeve to its full extent.
- Pipe is not included. IronRidge Ground Mount uses installer-supplied 2" or 3" Schedule 40 steel pipe (ASTM A53 Grade B, galvanized) or approved galvanized mechanical tubing. See the pipe specifications in IronRidge's Ground Mount manual.
- Engineering and permits. IronRidge says actual structural capacities are defined by PE-stamped project plans. Use IronRidge's Design Assistant and certification letters, and check local codes and soil conditions.
