Nite Ize S-Biner Stainless Steel Dual Carabiner, Sizes #2 to #5

Overview of the Nite Ize S-Biner Dual Carabiner | SB2 to SB5-03

The Nite Ize S-Biner Stainless Steel Dual Carabiner (SB2-03, SB3-03, SB4-03, and SB5-03 series) gives you two spring gates on one S-shaped clip. Clip your keys to your belt loop with one end and your pack with the other, or join two items that would otherwise ride loose.

Each S-Biner is made of weather-resistant stainless steel and comes in four sizes, from the 2 inch #2 to the 4.38 inch #5, in a black or natural stainless finish. Nite Ize rates them from 10 lb up to 100 lb depending on size.

Built for Everyday Carry

Patrol officers keep spare keys on a duty belt, EMTs clip a glove pouch to a jump bag, and preppers organize gear on a go-bag. One S-Biner handles all of these jobs.

• Two gates, two connections: clip to a strap and hold a second item at the same time.
• Not for climbing: Nite Ize rates the S-Biner for gear, not for people.

Key Features

• Dual spring gates: wire gates open from each end, so both loops close on their own.
• Stainless steel build: resists rust and weather for daily outdoor use.
• Four sizes: #2 (10 lb), #3 (25 lb), #4 (75 lb), and #5 (100 lb) weight ratings, per Nite Ize.
• Two finishes: black or natural stainless.
• Zipper lock trick: clip through two zipper pulls to keep a backpack, duffel, or suitcase closed.
• Care: wipe clean and dry after salt water or mud exposure.
