They are Weber replacement parts, not "off brand", but directly from Weber

Will these fit a genesis silver b grill?

I bought this for a Genesis series 300 copper. I don't really know if would fit your grill

Can the stems be trimmed? These stand two inches higher than the instrument panel on my Weber Spirit 320.

Trimming the stems will weaken them, and they will most likely break under any stress. Order the proper part for this grill by the model and serial number. Check with the manufacturer. This is for a Genesis, a much higher end grill. The sims may very well have a metal insert for support which will also complicate the issue. Call Weber and give them the proper information.

Perfect fit. Note: knobs fly off bouncing down the highway at 100 kph in my utility trailer. These are a perfect replacement.

These fit my 20+ year old Weber Genesis (with right-side control knobs) perfectly. Very good appearance, even though they don't look exactly the same. Price is reasonable. I would buy them again but the originals lasted over 20 years so I most likely won't have to.

Das Produkt ist zu 100% kompatibel. Beim Kauf auf die Seriennummer Ihres Weber-Grills achten. Einen Stern habe ich aufgrund des Preises abgezogen.
