Product Description
OZCO OWT Ironwood 4" Flush Inside 45° Angle Brackets
- Clean 45° connections — Makes tight, repeatable inside-angle joints on pergolas, arbors, playsets, and porch framing.
- Ironwood look — Rugged black hardware complements the OWT Ironwood line for exposed-connector designs.
- Outdoor build — Pre-galvanized steel with black powder coat; approved for ACQ-treated lumber.
- All-in kit — Plates and matching decorative hardware included for a finished install.
- Versatile layouts — Ideal for hip/valley rafters and diagonal bracing where a flush inside connection is preferred.
These Ironwood 4″ Flush Inside 45° Angle Brackets deliver the neat, consistent look that exposed-connector projects demand. The low-profile plates mount flush to the inside faces of your members, creating crisp, repeatable 45-degree joints without guesswork. OZCO’s Ironwood aesthetic pairs structural confidence with a finished, decorative appearance, so you can proudly showcase your connections instead of hiding them. Built from pre-galvanized steel and finished with a black powder coat, the brackets are made for weather and approved for ACQ-treated lumber. Use them anywhere you need tidy, diagonal reinforcement—hip rafters, knee bracing, deck accents, and more.
Planning your kit is simple: verify the 4″ bracket scale matches your material and lay out your rafters or braces to hit the bracket hole pattern. Start all fasteners loosely, align both faces, then draw the connection tight to seat the plates evenly. For cohesive styling on feature trusses, pair these with the Ironwood Truss Accent Plates (6″). When your design calls for a seated beam-to-beam connection instead of an angled face-to-face, step up to the Ironwood 6″ Beam Hangers for a snug, supported fit.
