The Most Advanced General-Use Rescue Carabiner on the Market. Rescuers working in the most demanding circumstances will appreciate our ProSeries Aluminum Carabiners, the first aluminum carabiners to meet NFPA strength requirements for general use. Combining high performance with minimum weight, these carabiners significantly reduce the weight of a rescuer's gear while maintaining the highest possible margin of safety. The patented key-lock design eliminates snagging when removing the carabiner from your harness, and a redesigned gate provides a full 1.1 inch (28 mm) opening on the standard size version and a 2.1 inch (53 mm) opening on the XL version. Gate choices include the traditional Screw-Lock, our easy-to-open-with-one-hand Auto-Lock and our innovative Manual-Lock. Both of the XL carabiners have a removable keeper pin. Every carabiner is proof loaded.
The SMC CrossOver series aluminum carabiners are the first biner to meet both NFPA G-rating 1983 and ANSI Z359.1 strength requirements. These carabiners feature a new ergonomic single hand frame geometry allowing easy single hand operations. The CrossOvers have been specifically designed to meet all your work environment safety needs. Easy to use Dual or Triple Auto-Locking sleeves allow for single hand operations while working in mission critical environments. A traditional non-ANSI Screw-Lock version is also available.
Designed to make belaying single-person loads with a Munter hitch easier and more efficient, these large, pear-shaped aluminum carabiners are available in Screw-Lok, Two-Stage Quik-Lok, and Three-Stage Quik-Lok models. The gate opening is 1 in (25 mm).
Every carabiner is proof loaded to an MBS of 23 kN (5,170 lbf).
