Buying Guide: Key Considerations For 4×4 Pergola Brackets
- Material and finish: Look for heavy-duty carbon steel or Q235B steel with a black powder coating to resist rust in outdoor environments.
- Post fit: Verify inner dimensions (commonly around 3.6 x 3.6 inches) to match your 4×4 posts, which often measure 3.5 inches on each side.
- Bracket type: Choose three-way or four-way configurations based on your frame design and load requirements. Three-way brackets are common for corners, while four-way brackets provide extra crossbeam support.
- Weather features: Drainage holes, moisture-proof designs, and full-coverage posts help prolong lifespan in rain-heavy areas.
- Installation: Pre-drilled holes and included hardware simplify setup. Check for compatibility with your crossbeam and post spacing.
- Ease of expansion: If you plan a larger pergola, select brackets sold in multi-pack options to cover multiple corners efficiently.
