ASA (UV-stable) is a UV-stable engineering polymer that survives full marine sun and salt without yellowing or embrittling. The a4/316 stainless hardware is the same alloy used on yacht standing rigging.
Made to order: nothing sits in a warehouse. No air freight, no surplus stock, no overseas factory.

- Will it fit my rail?
- See the sizing guide. If you're between sizes, round up.
- Does it scratch the rail?
- No. A TPU shock insert sits between the ASA cradle and the polished stainless. We tested it for a full season: no marks.
- How soon does it ship?
- Each part is made to order, then finished and checked by hand. We batch orders and ship 5 to 7 working days from purchase.
