Sit-on Frame Support

Many of my friends have complained that their sit-ons had limited mobility and that the ball attachment would squeak.

To fix these issues my sit-on incorporates the same unique double-ball upright as the Crowsfoot Studio Pedestal Stand that uses nylon balls to eliminate wear and squeaking. This gives me a great range of movement since it swivels top and bottom and the quick-release clamp makes for rapid angle changes or folding without having to readjust clamping force, and also makes it a very portable product.

I use high quality brass-insert knobs, which unlike wingnuts, eliminates slippage of bolts.
