How to Choose

  • Load: WLL from 200 lb (1/8") to 5,000 lb (1/2") – pick a link at or above your load.
  • Fit: the gate opening (A) must fit over your chain link or fitting – see the Data Sheet (PDF).
  • Stainless with stainless: use with stainless chain and fittings to avoid galvanic corrosion.

Installation & Safety

  • Unscrew the sleeve, pass the gate through the chain links or fittings, then screw the sleeve fully closed over the threads and snug it with a wrench.
  • For a semi-permanent connection, add thread-locker to the threads.
  • Load the link along its long axis. Do not side load or load across the gate, and never load it with the sleeve open.
  • Inspect before each use. Do not use a link that is bent, stretched, worn or has damaged threads.
  • Never exceed the WLL and do not shock load. Not for overhead lifting or lifting people.

FAQ

Why Type 316 stainless steel?
Type 316 has molybdenum added, so it resists salt water, chlorides and chemicals better than Type 304 or plated steel. It is the standard choice for marine hardware.

What is the working load limit of a 316 stainless quick link?
From 200 lb for 1/8" up to 5,000 lb for 1/2", for an in-line pull with the sleeve fully closed. See the Data Sheet (PDF) for every size.

How do I close a quick link?
Screw the threaded sleeve over the gate until it is fully closed and no threads show, then snug it with a wrench. Never load a quick link with the sleeve open.

Can quick links be used for overhead lifting?
No. Chain repair quick links are for tie-downs, rigging and general connections, not overhead lifting. Use rated alloy lifting hardware for lifting.
