A CLAM is a "Clip-on Load Adjusting Mechanism," a 1 cm thick shim that clips on to your oar sleeve next to the collar quickly and easily without any tools. Use CLAMs to change your inboard settings fast, without having to loosen or remove collars. Use one or two clams per oar for a 1 cm or 2 cm change in inboard. Use of more than two CLAMs per oar is not recommended.
Use orange CLAMs (part number 606—this item) if the sleeves on your oars are green or black. If the sleeves on your oars are white with replaceable wear plates, order blue CLAMs, (part number 600).
