Tree care seat harness for single rope ascent techniques. The SEQUOIA SRT is a tree care seat harness for ascents on a single rope. It has a ventral attachment point and a rear buckle for installing a CROLL ventral rope clamp with SECUR shoulder straps. The SEQUOIA SRT is designed for the arborist's comfort. The extra-wide, semi-rigid waistbelt and leg loops give excellent support. The attachment bridge is linked to two gated rings, allowing its length to be adjusted and accessories to be installed directly on the bridge. The harness also facilitates carrying and organizing work tools, with multiple equipment loops and retainers for attaching CARITOOL tool holders.
