Uneven heat on a grill usually comes down to the warming grids — and worn or missing ones leave the front of the cooking surface noticeably cooler than the back. The Sunstone R-FL-3B warming grids are the OEM replacement for the Ruby3B 30" grill, sold as a complete 3-piece set. Built from #304 stainless steel, they push heat from the rear burners toward the front of the grate so the whole cooking surface heats consistently, while their angled design sheds drippings toward the rear spill tray to cut down on flare-ups and simplify cleanup. A direct drop-in replacement when original grids are worn or when you're restoring a Ruby3B to like-new cooking performance.

Who It's For — The Deck & Den Take› This is the part for Ruby3B owners who've noticed the front of their cooking surface runs cooler than the back, or who are doing a full service and want to restore the grill to factory spec. The warming grids are the heat-riser layer between the burners and cooking grates — when they're worn or warped, heat distribution suffers. The R-FL-3B comes as a complete 3-piece set covering all three burner positions. These are Ruby3B-specific — the 4-burner (R-FL-4B) and 5-burner (R-FL-5B) grills use different sets sized for their respective footprints, so double-check the part number before ordering.

Manuals & Documents› Sunstone Full Product Catalog Frequently Asked Questions› What is the Sunstone R-FL-3B?› The R-FL-3B is a 3-piece #304 stainless steel warming grid set for the Sunstone Ruby3B 30" grill. The grids act as a heat riser between the burners and cooking grates, transferring heat from the rear of the grill toward the front for more even temperature distribution across the cooking surface. How many warming grids come in the R-FL-3B set?› The R-FL-3B includes 3 warming grids — a complete replacement set covering all three burner positions on the Ruby3B 30" grill. Which grill is the R-FL-3B compatible with?› The R-FL-3B is designed specifically for the Sunstone Ruby3B 30" grill. Other Ruby Series models use different warming grid part numbers — R-FL-4B for the 36" 4-burner models and R-FL-5B for the 42" 5-burner models. What do the warming grids do?› The warming grids sit between the burners and cooking grates and act as a heat riser, pushing heat from the back of the grill toward the front for more even temperature distribution across the cooking surface. Their angled design also sheds drippings toward the rear spill tray to help reduce flare-ups. When should I replace the warming grids?› Replace the warming grids when they are visibly worn, warped, or corroded, or when you notice the front of the cooking surface running significantly cooler than the rear — a sign the heat-riser function has degraded. Can I use the R-FL-3B on a RUBY4B or RUBY5BIR?› No — the R-FL-3B is designed for the Ruby3B 30" grill only. RUBY4B and RUBY5BIR models use different warming grid part numbers sized for their respective grill footprints. Does Deck & Den offer free shipping on the R-FL-3B?› Yes — Deck & Den offers complimentary shipping on all orders. See our shipping policy for full details.
