The Sked-Evac Tripod extends to ten feet high at the three anchors which are available to clip into. Each of the anchors is anodized red for easy identification, and all are equally well centered to handle a load. The anchors, header and legs are interconnected with stainless steel bolts to provide maximum strength. The header limits the distance the legs can spread. When at full extension this tripod allows you to bring the patient in a stretcher completely out of the hole. It is rated to handle an NFPA rescue load. Included with the tripod is a chain which passes through the feet to provide greater strength and stability. The chain will not degrade in acids or chemicals like nylon straps or ropes. The legs are adjustable in 5" increments, and Skedco provides safe working load data for each tripod height on each tripod. Brackets are available for mounting most popular winches. Made in USA.
