ISC Compact Oval Supersafe Carabiner

The ISC compact oval carabiner with a Supersafe gate is a small, symmetrical connector for micro pulleys and compact hitch systems. Its auto-locking gate is designed to resist accidental opening against rope and bark.

Why go compact

A smaller oval keeps a hitch system short, which means the hitch sits closer to your bridge and you lose less height when tending slack. It also cuts bulk and weight on a saddle already loaded with lanyards, saws and slings.

The oval shape keeps a micro pulley or swivel centered so it runs true. The Supersafe gate is ISC's auto-locking design; take time to practice opening it with gloves so you can work it smoothly in the tree.

Because compact ovals have less room, they suit dedicated setups where the same pulley and hitch stay together. Keep the gate clean, rinse grit out after muddy climbs, and retire the carabiner if it is dropped onto a hard surface from height, shows grooves, or the gate fails to close and lock on its own.

Use and inspection

Check that your pulley and hitch cord eyes fit inside the compact basket without crowding the gate. Read the strength markings and ISC's instructions before use.

Carabiners in a climbing system are life-support gear. Use only connectors rated for the purpose, follow ANSI Z133 and the maker's instructions, load them along the major axis, and inspect the gate, spring and body before each use. See more auto-locking carabiners.
