The BBQ Republic Promise
The official Masterbuilt large cover for the Gravity Series 1150, Gravity Series XT and Gravity Series 1050. Sized and constructed specifically for the large-format Gravity Series footprint. The 1150 is a significant investment and leaving it uncovered between cooks accelerates wear on painted steel, electronics, and the digital control panel. This cover fits properly and stays put in wind. Masterbuilt describes it as durable and water-resistant, with a tear-resistant PVC-lined interior, double-stitched seams and a locking buckle.

What It Is Built From
Durable water-resistant outer
Masterbuilt describes the outer as durable and water-resistant, made to shield your Gravity Series grill from the elements year-round.
Tear-resistant PVC interior liner
The interior is lined with tear-resistant PVC to prevent damage from repeated on/off use, particularly around the hopper and control panel sections where the 1150's profile is uneven. Without a liner, friction from these edges tears the fabric from the inside over time.
Double-stitched seams
All seams are double-stitched to help keep water out at the stitch points during heavy or sustained rainfall.
Locking buckle closure
A locking buckle at the base keeps the cover firmly in place rather than lifting in wind. More secure than a drawstring for a cover of this size and weight, and appropriate for the larger footprint of the 1150.
Year-Round Protection
Sun ages painted surfaces. Moisture works into joins and electronics. Windblown debris and coastal salt air do slow, cumulative damage that is not obvious until it is. A fitted cover helps protect against all of it.
Rain and sustained moisture
Water-resistant outer and double-stitched seams keep rain out of the enclosed cart, electronics, and cooking chamber.
Sun, dust and debris
Covering the grill between cooks keeps direct sun, dust and debris off the painted surfaces, lid and control panel.
Wind and airborne debris
The locking buckle closure keeps the cover secure and prevents windblown material getting inside the unit.
Coastal salt air and frost
Helps protect metal components, the digital control panel and electronics from salt air and overnight frost during colder months.

Keeping the Cover in Good Condition
- Always allow the grill to cool completely before fitting the cover. The grill body can stay hot for some time after a cook, so allow adequate time before covering.
- Never place the cover over a warm or hot surface. This damages the cover material and creates a fire hazard.
- Wipe down with a damp cloth for routine cleaning.
- For a more thorough clean, remove the cover, hose it down, and allow it to air dry completely before refitting.
- Do not machine wash or use harsh detergents on the cover material.
- Store the cover on the grill rather than folded away when not in use for longest life.
Which grills does it fit?
Made to fit the Masterbuilt Gravity Series 1150 and the Masterbuilt Gravity Series XT. For the Gravity Series 600, choose the Small cover. See all Masterbuilt smokers.
