The Leverloc Anchor Trolley- HD is a high-tech anchor trolley system featuring Harken pulleys, a built-in Leverloc and 35 ft. of 550 Para-cord with a reflective tracer for visibility. This item also includes backing plates for added strength and durability. The built- in Leverloc locks the trolley line by the simple flip of a switch, and at .4 in. tall it is incredibly low profile making for a snag free installation. When not in use the anchor ring snaps into the Leverloc so you always know where it is. This anchor trolley is a first of its kind using specially engineered components that are specific to the job.
