The STIHL ADVANCE X-Flex tree calliper holder is part of the STIHL ADVANCE X-Flex modular harness system.The pre-tensioned padding in the holder ensures that the tree calliper always remains reliably in its position. The tree calliper holder is angled and attached to the STIHL ADVANCE X-Flex hip belt, and the positioning means that even long tree callipers do not restrict freedom of movement, while still being easy to remove. The STIHL ADVANCE X-Flex tree calliper holder can be attached to the STIHL ADVANCE X-Flex waist belt using the sturdy STIHL attachment clips.
