Berth mooring is a tough mix: salt water, constant tension and chafe. How stainless chain, wire rope and fittings are used on docks, pontoons and boat lifts.

One is carbon steel with a zinc coating, the other is a corrosion-resistant alloy through and through. How to decide which chain a job needs.

Chain size is not one number. Diameter, inside width and link length each decide whether a chain fits - here is how to measure the chain you have and what to send when you order.

One holds a chain at a fixed point, the other lets it slide. How grab hooks and slip hooks differ, and how to choose the right one for a tie-down.

A coated chain is a steel core with a cover. What PVC, plastic powder coating and zinc coatings each do, and how to pick the right cover for the job.

Both clamp a rope between a U-bolt and a saddle, but they are made differently and sized in different systems. How to choose the right wire rope clip for your rope and market.

Hammocks, porch swings and hanging furniture all ask the same of their hardware: hold a load outdoors, in the weather, for years. What to hang them with.

One is the chain as manufactured, with no coating at all; the other carries a zinc layer for corrosion protection. Choose bare steel when it is enough, and galvanized when it is not.

Wire rope rarely fails without warning. What to look for, where to look, and how to decide between a rope that still has life in it and one that has to come off.

Carbon steel, alloy steel or stainless steel - and a grade number on top. What the steel types are, what the grade number measures, and why material and grade are not the same thing.
