A14 Anti Rotation Pins for Accessories | 4-pack

These items are used as anti-rotation pins to prevent an Arca Swiss plate from rotating when tightened down to a Manfrotto type plate. These pens should screw into place so they don’t fall out when the plate is lifted, but unfortunately, they do not and so are prone to falling out and they are quite small and easily lost. They can be held in place with some blue Loctite, which is what I do but this was not recommended by the manufacturer although it’s really the only solution.

These are used to prevent rotation of the arca-swiss plate but they dont screw in and easily fall out when attempting to rotate the plate to accomidate the foot of a long lens. These can be better held in place with some blue loctite. Clearly this is a design flaw.

They work. They keep things from rotating. You don’t need to tighten things too much.
