The SR Steel is a high strength carabiner for technical rescue and industrial applications where high loads are expected. The SR Steel features a key lock design and has a wide gate opening for stacking multiple ropes or slings. Manufactured in USA and certified to NFPA 1983 General-Use.
Screwgate carabiners have a barrel that moves vertically on a threaded gate. When closed the barrel creates a secure connection between the carabiner and top of the gate, locking the carabiner closed. Screwgate carabiners can come open and should be second checked before loading.
