Product Description
OZCO® OWT™ Ironwood Post-to-Beam Bolt Offset Connector — 2-Pack (For 6″+ Posts)
- Offset Bolt Pattern — Top plate uses offset bolt holes to maximize bite and spacing on the beam
- “Third Hand” Ledge — Integrated post ledge base supports the beam while you mark and fasten for faster, safer installs

The Ironwood Post-to-Beam Bolt Offset Connector is a contractor-favorite for joining heavy beams to 6″ or larger posts. The ledge base holds the member while you align and mark; the interlocking top plate bolts through the beam for a strong, repeatable connection that looks as good as it performs. With heavy-gauge galvanized steel and a black exterior powder coat, it’s built for pergolas, pavilions, porch roofs, and other outdoor structures.
Why Choose This
- Faster layout — Ledge supports the beam so one person can position and fasten
- Reliable connection — Offset top holes spread load and reduce fastener conflict
- Built to last — 3/16″ galvanized substrate + powder coat for long service life outdoors

Position the top cover plate, then drill and install the required OWT Timber Bolts through the top holes. Use the included OWT Timber Screws only for the bottom hole placement. Tighten hardware, verify alignment, and repeat for the opposite side.

- Don’t forget fasteners: Add OWT Timber Bolts (top holes), plus matching Hex Cap Nuts to finish exposed faces.
- Coordinate the look: Keep extra OWT 1/4″ Timber Screws on hand for adjacent OWT brackets.
