The Ark Angled Wood Yoke Bracket is an adjustable post for your skids to be mounted on. Galvanized and with a 19mm squat stem, they are designed for use with skids, as opposed to, or in conjunction with rollers. Skids maximise support and make launching and retrieving your tinny a breeze. Worn or damaged skids can cause your boat to come onto the trailer crooked, or not level. You'll never have that problem again with this adjustable bracket.
