Buying Guide
What size bracket do I need?
Bracket size should match your platform dimensions. Larger platforms distribute load better and may reduce mount point stress, while compact brackets save space but still must support required weight.
Why is the angle important?
The angle controls how weight is distributed across the mounting points. Common angles range from 12° to 16°. Choose an angle that aligns with your deck geometry to minimize stress and maximize stability.
What material should I pick?
304 stainless steel offers excellent corrosion resistance in saltwater and freshwater. Heavier marine use or exposed environments may benefit from stamped 304 stainless brackets for durability and long service life.
What about hardware and installation?
Many brackets come with stamped hardware but may not include all fasteners. Verify the required bolt type and length (commonly 1/4″ FH) and have appropriate mounting hardware on hand.
Compatibility considerations
Ensure the bracket pattern matches your platform’s mounting holes. Some brackets assume standard deck thickness and platform thickness. Check both the bracket dimensions and your deck specs before purchase.
Which bracket is best for my vessel?
For mid‑sized boats with standard platform configurations, the 9″ x 17″ 12° bracket is a versatile all‑around choice. For tight spaces or smaller boats, the 6″ x 12″ options with 12° or 16° angles offer a compact yet sturdy fit. Longer brackets suit decks with extended spacing, while multi‑angle designs provide flexibility for various configurations.
Maintenance tips
Rinse brackets with fresh water after use in saltwater, dry completely, and inspect for signs of wear or corrosion. Tighten mounting hardware as part of routine checks to maintain safety and integrity.
