Buying Guide
- Material matters: For saltwater or marine-heavy use, stainless steel (316 SS) offers superior corrosion resistance. For budget projects, galvanized or cast iron with protective coatings can be effective if maintained.
- Base design: Open-base cleats generally provide more stability on uneven surfaces; closed or flat-top designs can reduce snagging and wear on lines.
- Size and mounting: Ensure mounting hole spacing matches your dock or deck configuration. Check base footprint to prevent wobble and rope slippage.
- Hardware included: Some products ship with bolts, nuts, and screws; others require separate hardware. Including hardware can simplify installation and save time.
- Installation considerations: Hexagonal holes and simple alignment features can speed up mounting. Verify whether drilling or welding is needed for your setup.
