The iconic S-Biner design allows quick and easy attachment using its unique double-gated design. Designed for aquatic environments and constructed from 316 stainless steel, these marine-grade S-Biner SlideLocks are highly corrosion resistant and have the benefit of independently locking gates for an extra-secure hold of your keys or gear.



In aquatic environments, only the strong survive, that's why the highly corrosion-resistant S-Biner Marine SlideLock is crafted from high quality 316 stainless steel. This locking double-gated carabiner allows you to organize, connect, carry, and keep valuables extra secure in marine or other extreme environments. It features two innovative plastic sliders that lock into place to keep the gates securely closed. Each gate can be locked independently for convenient access, and will stay that way until you choose to unlock them.

    S - Biner Marine Slidelock

    Posted by Jack Pratt on 10th Feb 2022

    Excellent in every way ! Even though I miscalculated the size - next time I must order size # 3 instead of # 2. However I found a good use for the two # 2 I bought. One supports my Olight mini key chain light, and the other my mini knife by Mora. Both can now be suspended from my pack shoulder straps. So all good. I 'll order the number # 3 size for different use. As I say excellent in every way. The stainless steel looks good.
