Nite Ize LSB3-11-R6 S-Biner Stainless Steel Slide Lock, Size 3

Great for clicking on to a satchel or backpack to hold a hat or umbrella. The version with the sliding lock is better than the basic unit.

We've been using Nite Ize for years, in particular these S-Biners in various sizes, but this locking version is a clever concept because it works, and works brilliantly!It will secure my handbag to my bicycle, or anywhere that is secure because sliding up those small bars until you hear and / or feel a little 'thunk', you know that the S-Biner is well and truly locked.They are tough, dependable and sturdy. For this stainless steel version, though, I suggest a light oiling to keep it was rusting. I'm not saying its stainless steel will rust, but it might if the weather keeps chucking it down.I am very pleased and recommend. Even the black version is awesome.
