This heavyweight karabiner is primarily fitted to the ends of fall arrest lanyards and horizontal temporary anchor lines, due to its high minimum breaking strength.
The twistlock closure makes this karabiner very safe to use, as it locks automatically when it is clipped into an anchorage point. The RGK3 is similar to the RGK2 except it is stronger and has a larger gate opening. The gate is extra strong as required by ANSI Standards.
