Large pear-shaped carabiner ISC KH407:

The ISC KH407 carabiner is a large steel carabiner designed for aerial rigging applications requiring a wide gate opening. Its pear shape and large gate opening allow it to be easily attached to bulky anchor points or rigging equipped with large metal rings.

This model is particularly well-suited for installing 3-strand aerial ropes, whose metal eyelets require a carabiner with a large opening. Its robust steel construction allows it to withstand heavy loads while remaining easy to handle.

The carabiner features a double-rotation screw locking system and comes with a captive pin to hold ropes, cables or chains in the correct position on the carabiner.

NetJuggler's review of the ISC KH407 carabiner:

The KH407 is a highly regarded rigging carabiner for aerial installations requiring ample space and robustness. Its wide 53mm gate opening sets it apart from standard carabiners and allows for easy attachment to bulky anchor points, heavy slings, or metal eyelets found on some aerial ropes. The steel construction provides excellent mechanical strength and durability. Its double-rotating screw locking system minimizes accidental openings during use. This type of carabiner is particularly well-suited to professional environments such as circus schools, training studios, aerial structures, and technical installations.
