The Petster is a temporary anchor designed to provide a single worker with a portable anchor point on panel walls with a thickness of 60-360mm. Suitable for various anchor applications including window washing, construction, emergency and rescue situations, the Petster has a rigid steel alloy body with a rubber padded fixed arm and one rubber padded adjustable arm (with multiple pin sets). The anchor tightens to the parapet by use of the screw levers with padded rubber discs.
