Function and Design
A control knob gives the operator a simple way to adjust an HVAC switch or control.
It can help restore normal control use when the original knob is missing, worn, or damaged.
The BT2-4009 knob has a compact rectangular style with a shaped grip area.
Because knob fitment depends on shaft style, size, and orientation, compare your current knob before ordering.
Durability and Layout

Cab controls often face repeated use, vibration, and temperature changes.
This knob is part of the Coyote Series C control family.
However, appearance may vary between related knob versions or interchange numbers.
Always verify the knob profile and control shaft before installation.
Installation
Install this knob by aligning it with the control shaft.
Then press or fit it into place according to the control design.
Before installation, confirm the shaft size, knob orientation, and control panel layout.
Do not force the knob if the shaft or opening does not match.
