Overview
The Glowye 6788 is a full-size carbon steel griddle insert, 25.6 x 18.67 x 1.19 in, built to drop into a Weber Genesis II 300-series or LX E/S-340 gas grill in place of the stock grates.
It converts the whole grate area into one flat cooking surface with high sidewalls to hold in grease and a tray to channel it away, plus dual handles for lifting it out. The maker recommends oiling and heat-cycling it 2-3 times before first use, and it isn't dishwasher safe.
- Fits Weber Genesis II 300-series (2016+) and LX E/S-340 grills
- 25.6 x 18.67 x 1.19 in carbon steel griddle
- High sidewalls with a full-width grease tray
- Season with oil and heat 2-3 times before first use, hand wash only
Who it's for
Fits Weber Genesis II 300-series owners (E-310/315/325/330/335, S-310/335, and related EX/SX/EPX/CSE/CSS 325s/335 variants) or the Genesis II LX E-340/S-340/CSE-340/CSS-340, who want pancakes, eggs, and smash burgers without buying a separate griddle.
What buyers say
From Amazon customer reviews.
Most reviewers who confirmed correct fitment call it easy to clean and effectively non-stick once seasoned by the included instructions, with one describing the surface as almost too slick to grip food. The detailed negative review argues the coating is not the same as Weber's own bare carbon steel griddle, that it won't take a reseasoning, and that metal grill tools will damage it over time. One buyer returned it, saying it simply didn't work for their setup despite ordering the correct size.
Strengths and trade-offs
Drawn from this product's published specifications.
- Coated surface reportedly won't accept reseasoning the way bare carbon steel does
- Metal utensils can damage the coating, per one detailed review
- Heat runs noticeably hotter at the front near the burners
- Not dishwasher safe
Performance notes
High sidewalls and a full-width grease tray are meant to keep splashes contained while cooking, and the dual handles make it easier to lift on and off the grill. Reviewers who seasoned it as instructed describe a genuinely non-stick surface, though heat runs hotter toward the front near the burners, so food needs to be moved around rather than left in one spot.

Questions about the Glowye griddles
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Which Weber grills does the Glowye 6788 griddle fit?
Genesis II 300-series models from 2016 onward (E-310/315/325/330/335, S-310/335 and related variants) and the Genesis II LX E-340/S-340/CSE-340/CSS-340.
Do I need to season it before cooking?
Yes, the maker recommends coating it with oil and heating it to smoking point 2-3 times before regular use.
Can I use metal spatulas on it?
One long-term reviewer reports the coating does not hold up to metal utensils and won't take a reseasoning the way bare carbon steel does, so a plastic or wood turner is the safer choice.
