Replacement Control Knobs for Summit Grills

This set of two main control knobs is manufactured by Weber for specific Summit gas grill models produced between 2007 and 2009. They are designed to replace worn or damaged original knobs on compatible units. The parts carry the manufacturer part number 70377 and are sold as a pair.

Owners of Listed Summit Models Needing Direct

These knobs fit 73 documented Summit model variations including E-450, E-650, S-420, S-440, S-450, S-620, S-640 and S-650 series in both LP and NG configurations. Buyers with Summit grills outside the listed model numbers or production years should verify compatibility before ordering. Grill owners requiring different knob types such as side burner or rotisserie controls will need separate parts.

The set includes two identical main control knobs, allowing users to replace both the left and right primary burner controls simultaneously. This ensures consistent feel and appearance across the control panel. No tools, hardware or additional components are included in the package.
