• Added top cover plate to keep out rain, critters and outdoor elements.
• Solid 18 ga construction replaces the flimsy, swinging, open standard grease bucket included on all pellet grills.
• Added lock for safety and to prevent spills.
• Sleek & Customized fit that looks like part of the grill, replacing the eye sore of a cheap grease bucket.

Installation is a direct connection to the vertical threaded grease spout after removal of the shut off valve. The Grease Box GX-U attaches to the +Thread Adapter L with thumb nuts.

Recommended to clean after each use for cleanliness and proper function.
