Snap Shackle 316 Stainless Steel Swivel Shackle Sailing Halyard, Quick Release Snap Hook Boat Shackles Sailboat Hardware for Sailing Rigging Shackles

Easy one hand operation. I use these for a dock line and clip them to a cleat on a PWC

Great assembly

I am using these shackles for a non-standard purpose. They are subjected to a heavy load and have held fine. We found that to release the shackle under load that you must pull the release in line with the pin. My only concern is that the release pin is held in place with a simple wire keeper ring. That ring cannot handle a heavy pull to release the pin. Again, I am using the shackle for a non-standard application so the wire ring is probably fine for its intended purpose.

I am using this to support my davits and dinghy. the one on the dinghy had the pin fall out and sink in the water after opening shackle. It had not been used more than 3 days. moivng up to 4 star from 1, as company read review, contacted me for full refund. Excellent company to work with .

Exactly what you would expect. I'm using them to lift a 450lb dinghy up. Using 4 of these .
