Petzl GRILLON is a highly adjustable work positioning lanyard. The GRILLON allows you to get comfortably positioned at your work station in two ways: attached to side positioning loops on the harness or vertically hanging from the central chest D-ring. This positioning lanyard must always be combined with a fall arrest system. The Petzl GRILLON work positioning lanyard meets or exceeds all US OSHA and ANSI standards for positioning lanyards. The GRILLON is used by tower climbers doing energy work or maintenance on broadcasting towers as well as by network and cellular technicians and wind energy workers. It provides exceptionally smooth and precise adjustment to make at height work that much easier.
