Quick & Lap Links
What Are Quick Links and Lap Links?
Quick links and lap links are essential chain-connecting hardware used throughout marine, RV, and outdoor applications. Quick links, also known as rapid links or maillon rapides, are versatile rigging connectors featuring a threaded sleeve or screw gate that allows fast, secure connections without tools. Lap links, on the other hand, are the most economical way to join two lengths of chain — or connect chain to rings, snaps, or other hardware — and are typically closed permanently with a hammer or vise.
These small but critical components show up in a wide range of tasks aboard boats and RVs: securing anchor chains, connecting mooring hardware, repairing dock lines, and linking trailer safety chains. Understanding the difference between the two helps you choose the right solution for the job.
Quick Links vs. Lap Links: Choosing the Right Connector
Quick links are designed for semi-permanent connections that may occasionally need to be opened and reclosed — such as permanent rigging points, anchor system assembly, or securing equipment that stays connected for a season. Their threaded closure provides a more secure hold compared to spring-loaded carabiners, while still allowing removal when needed.
Lap links, by contrast, are best suited for more permanent repairs and connections. Once a lap link is hammered shut, it forms a solid, load-bearing coupling in the chain. This makes them ideal for field repairs and one-time assembly where the joint won't need to be regularly undone.
Material Matters: Stainless Steel vs. Zinc-Plated
For marine environments, material selection is critical. Saltwater accelerates corrosion on standard steel hardware far faster than most people expect. 316 stainless steel is widely considered the gold standard for saltwater use, as it contains molybdenum for superior corrosion resistance. 304 stainless steel offers reliable performance in freshwater and general-use applications at a more economical price point. Zinc-plated steel links are a lightweight option well-suited for temporary connections and less corrosive environments, though they are not recommended for permanent marine or overhead applications.
Applications on the Water and at the Campsite
Quick and lap links serve a surprisingly broad range of uses. On a boat, they connect anchor chain to shackles, join mooring lines to cleats, and secure rigging on sailboats. On an RV or trailer, they are commonly used in safety chain systems and tow connections. Their compact, tool-free design makes them easy to carry onboard as a backup repair solution for nearly any chain or rigging assembly.
