The Garland 4512145 HI-LO Knob Assembly provides dependable, clearly visible control for compatible commercial cooking equipment. This complete assembly includes a D-stem adaptor, set screw, and dial insert, creating a secure connection between the operator interface and the equipment control shaft. Its black-and-silver finish offers clear visual distinction while the HI-LO markings help operators quickly identify the selected heat level during busy kitchen service. Designed for repeated manual adjustments, the assembly can restore proper control when an existing knob is damaged, loose, worn, or missing its supporting hardware. Replacing the complete control assembly can simplify installation and help maintain consistent equipment operation. Verify the equipment model, shaft style, and control configuration before installation.
