Description

The Sunstone Insulating Grill Jacket (SUN5BJK) protects a 42" built-in gas grill installation and the surrounding outdoor kitchen from radiant heat. It is 44-1/8" wide and fits standard 42" built-in grills running on natural gas or propane.

The jacket is 304 stainless steel and weighs about 45 lbs. It is self-rimming, so it sits cleanly in modular cabinet systems. Bottom venting improves airflow to the burners, and universal connection ports on the left and right suit different island layouts.

An extra-wide drawer stores BBQ accessories or uses leftover heat to warm bread and side dishes.

Important for safety

Fit perfectly in my outdoor kitchen island with my 42 inch Sunstone grill. Gives me real peace of mind with combustible materials around it. Install was straightforward and it feels really sturdy.

Elaine M.★★★★★September 23, 2009
Great fit and protection

Installed this with my new 42 inch Sunstone grill and couldn't be happier. Clearly built to last and it fit right into my custom cabinets. Knowing the grill and the house are protected makes grilling more enjoyable.

Angie B.★★★★★June 30, 2019
Solid build, peace of mind

I'm a contractor and I always recommend an insulating jacket for built-in grills. This one is well built and sized right. You need one for a safe install, especially with wood or composite materials.

Warren G.★★★★☆January 14, 2018
Does the job, a bit pricey

Works as advertised and protects my outdoor kitchen well. Easy enough to install. Only gripe is the price, it feels a little steep for what it is, even though you need it for safety.

Kristen H.★★★☆☆December 14, 2025
Good protection, tricky install

It does give my 42 inch built-in grill the fire protection it needs, which is the main thing. Install was more finicky than I expected though, I had to make some extra adjustments to get it flush in my island. Doing its job now.

Questions & answers

5 questions answered

Q
Will this jacket fit my 42 inch grill from another brand, or only Sunstone?Asked by Sunstone Support Team
A
It's sized for Sunstone's 42 inch built-in grills, but it fits most other major brands of 42 inch built-ins too. What matters is your grill's outside dimensions and cutout requirement. Compare your grill's specs against the jacket's inside dimensions to make sure it fits properly and safely, especially with a non-Sunstone grill.

Q
How hard is this grill jacket to install? Do I need special tools?Asked by Sunstone Support Team
A
With basic DIY skills it's pretty easy. It fits a standard 42 inch built-in grill cutout, and you'll usually just need a drill, screwdriver and level. It comes with clear instructions, and pre-drilled holes make mounting the grill inside fairly simple. It usually takes an hour or two, depending on your island.

Q
What's this jacket made of, and how does it hold up outside?Asked by Sunstone Support Team
A
It's high-grade 304 stainless steel, which resists corrosion really well outdoors. With its double-wall insulated design, it handles the heat from your grill and stands up to weather, rust and UV for years. It gives your outdoor kitchen fire-safe protection that lasts.

Q
How do I keep this jacket looking good?Asked by Sunstone Support Team
A
It's simple. Most of the time a soft cloth with warm soapy water wipes off grease and dirt. For tougher stains or to bring the shine back, use a stainless steel cleaner. Avoid abrasive cleaners and scouring pads, they'll scratch the finish. Regular cleaning keeps it looking good and helps it last.
