Overview
The rundown on the Hopper Lid Latch Kit
Keep your Masterbuilt Gravity Series performing at its best with the genuine Hopper Lid Latch Kit (Part No. 9904190043). The charcoal hopper is the heart of the Gravity Series' legendary heat performance — it's what allows this grill to reach scorching temperatures in minutes and hold them with rock-solid consistency for low-and-slow BBQ perfection. A worn, loose, or broken latch compromises that sealed environment, letting heat and airflow escape exactly where you don't want it. This OEM replacement kit restores the hopper lid to factory-tight condition, so your fire management stays precise and your smoke stays where it belongs — in the cook chamber.
Designed specifically for Australian backyard entertainers who refuse to let a small mechanical issue sideline a big cook, this latch kit is the no-fuss fix that gets your Gravity Series back in action fast. Whether you're pulling an all-night brisket, reverse-searing a thick rib-eye, or firing up the grill for a weekend gathering, a properly latched hopper means consistent charcoal feed, stable temperatures, and that unmistakable wood-fired flavour every time. Using genuine Masterbuilt parts ensures a perfect fit and long-lasting durability — no rattling, no gaps, no compromise on your BBQ game.
