Our Clip-on Load Adjusting Mechanism (CLAM, for short) provides a quick way to adjust load with no tools required. It’s so easy you can even do it on the water.

Each CLAM provides 1 cm of inboard and is a convenient alternative to moving buttons if your crews are sharing oars between an eight and a four, you’d like to quickly test different loadings with your crews, or you find yourself in a headwind after a long row. They also provide a great wear surface between the collar and the oarlock.

CLAMs are included with every new oar purchase and can also be purchased separately.

Important: CLAMs are designed for use with current production Concept2 sleeves only and may not fit properly on other sleeves.
