Powr-Flite Handle Lock Knob
$8.99
Product details
SC311 is the handle lock knob, the hand-tightened knob that clamps the handle at the angle you set and holds it there while the machine is in use. It is a small piece of hardware with a job that becomes obvious the moment it stops doing it.
- Part number: SC311
- Type: handle lock knob
- Sold: each
Knobs like this wear out from being tightened by hand hundreds of times. The usual endings are stripped threads, a cracked body that no longer takes any torque, or a knob that turns freely without ever clamping. Once the handle will not hold its position the machine becomes tiring to control, and operators tend to compensate by over-tightening whatever is left, which finishes the part off.
No published model list is attached to this knob, so match it against your machine's parts diagram or the knob you are replacing before ordering. Ships to you in 2-5 business days.
