Buying Guide
- Depth and width compatibility: Choose brackets that accommodate your planter box depth (commonly 6–12 inches) and width. Slider bases offer flexible sizing for irregular planters.
- Load capacity: Consider total planter weight when loaded with soil and plants. Look for brackets rated to handle at least 40–70 lbs per pair to avoid sagging.
- Mounting surface: Assess whether your mounting surface is wood, brick, or cement. Some brackets include multiple screw types or hardware for varied substrates.
- Durability and finish: Powder-coated iron or steel resists rust, chipping, and corrosion, extending outdoor life in wet climates.
- Installation ease: Sets that include all hardware and clear instructions save time. Some brackets allow wall, window, railing, or deck mounting versatility.
- Aesthetics and space: If you have limited balcony space, consider brackets with compact profiles or those that align flush with the wall for a cleaner look.
