Who It's For

This kit is aimed at Weber Summit owners who have models manufactured from 2007 onward and who want a straightforward, model specific conversion to propane without sourcing multiple replacement parts. It is best for home cooks who value stability of flame and a kit that includes regulator hose and assembly tools.

Those who should look elsewhere are users with non-Summit models, owners of much older Summit grills before 2007, or anyone who prefers a universal conversion approach rather than a model specific kit. Also, professionals seeking factory OEM parts may prefer parts directly from the grill maker.
