3 -in -1 tripod hook (3/16",1/4",1/2") increases your placement options without increasing weight or the fumble factor of having multiple hooks clipped into each aider. Lower points act as outriggers, friction to rock and stabilize each placement. Tread with 1/2 x 24" webbbing or add optional 12mm ULTRATAPE SLING which is strong, low bulk and can't come untied.
