Petzl Ring-S (Small) for Petzl Sequoia work positioning harnesses. Attach directly to the Petzl Sequoia bridge for improved lateral mobility and then connect your climbing system directly to the ring. The bridge can easily be removed on the Petzl Sequoia harness - simply unscrew the gated rings (use a 25mm male Torx driver for pre-2014 harnesses and a 3mm HEX on the later models), slide out the plastic spacer and follow with the bridge eye. Slide the Ring-S onto the bridge and replace in reverse order - don't forget to add a drop of Loctite to the Torx thread for added security - the HEX model has a sealed O-ring so no need for Loctite
