Carpet Pro Power Nozzle Hei...
$6.99
Product details
Height adjust wheel for a Carpet Pro power nozzle, molded with an overmold grip so fingers do not slip when turning it. Part B350-3942 is the wheel itself, the knob you turn to change the nozzle's carpet-pile setting, not the clamp or spring behind it.
The overmold is usually what fails first. Rubber peels away from the hub with age, and once it does the wheel either spins without engaging the mechanism or seizes at one height. A nozzle stuck too low drags across pile it should clear, and one stuck too high never lets the brush reach the floor.
- Part: height adjust wheel, overmold grip
- Vendor part number: B350-3942
- Vendor: Carpet Pro
Compare the wheel diameter and mounting boss against the part you are removing before ordering, since power nozzle height-adjust hardware differs across Carpet Pro's nozzle lineup. The clamp and tension spring that sit behind this wheel wear out on their own timeline too, and both are stocked separately from the wheel itself.
