The Nite-Ize Slidelock Carabiner #4 is made with strong stainless steel and features a slide to lock mechanism to provide excellent security for your gear.
The slide-lock easily moves with a push and slide to both lock and unlock and is ideal for attaching keys, water bottles, tools and similar items to belt loops, rucksacks and other equipment.
The carabiner has a slim low-profile that makes it flatter than other carabiners and will conveniently lie flat in a pack or pocket.
