Sit-stand systems (also known as frog rig) - one ascender is at chest level attached to the sit harness, and a second is held in the hand with a long loop of rope for the feet. Movement up the rope is by repeated moving of the foot loop ascender up the rope, pushing up with both feet together, and sitting, supported by the chest ascender.
The ascender will glide smoothly up the rope when the belayer takes in slack. If the climber falls, the ascender will lock up. (I’m giving them the benefit of the doubt and assuming that the ...

The Blake's hitch is a friction hitch commonly used by arborists and tree climbers as an ascending knot. Unlike other common climbing hitches, which often use a loop of cord, the Blake's hitch is formed using the end of a rope.

While traditional auto belays use a top roping format with the device hanging from the top of the route, in 2021, a new type of auto belay–the lead auto belay–was developed that used a lead climbing format (i.e. the climber clipped into the quickdraws like a normal lead climb on a sport climbing route), where the device was fixed to the bottom of the route.
