Frame the island to the jacket, not the grill. The SUNJK33 needs 31-1/2" wide by 24-1/4" deep by 13" high, the SUNJK40 needs 38-3/4" wide and the SUNJK45 needs 43-1/2" wide, both at the same 24-1/4" depth and 13" height.
Overall jacket sizes are 33-1/4", 40-1/4" and 45-1/4" wide, each 25-3/4" deep and 14-1/4" high.

The sleeve is 26" wide on the SUNJK33, 34" on the SUNJK40 and 39" on the SUNJK45, each 22" deep and 10" high with the vent panel in place, or up to 12" high with the vent panel removed.
The grill rests on the jacket's top edge rather than on its base, which leaves space below the drip pan for air flow. Sunstone notes that the jacket raises the grill 1" above the counter.

On its own a Ruby 30" RUBY3B needs a 27-1/2" x 22" x 10" cutout; with the SUNJK33 the opening becomes 31-1/2" x 24-1/4" x 13". The Ruby 36" RUBY4B and RUBY4BIR go from 33-1/2" x 22" x 10" to 38-3/4" x 24-1/4" x 13" with the SUNJK40, and the Ruby 42" RUBY5BIR goes from 39-1/2" x 22" x 10" to 43-1/2" x 24-1/4" x 13" with the SUNJK45.

Sunstone's Ruby Series manual asks for 24" of clearance from combustible materials in any direction of the grill. If any combustible material is within that 24", the manual calls for a heat barrier such as a grill jacket, or non-combustible material such as brick, cement board or metal.
The manual also says the 24" clearance under the countertop to combustible construction can be modified by use of an insulated jacket. Check your local code before you finalize the island, and read do you need an insulating grill liner? for more.

The Sunstone SUNJK insulated jacket is the heat barrier Sunstone pairs with its current Ruby built-in grills. Sunstone offers it in three widths, each matched to specific grills: the 33" SUNJK33 for the Ruby 30" RUBY3B, the 40" SUNJK40 for the Ruby 36" RUBY4B and RUBY4BIR, and the 45" SUNJK45 for the Ruby 42" RUBY5BIR and Emerald 42" EMCHDZ42. The grill drops into the jacket's sleeve and rests on its top edge, and the jacket sits in a larger island opening than the grill would need on its own, so plan the cutout around the jacket before the island is framed.

These SUNJK jackets replace Sunstone's earlier SUN3BJK, SUN4BJK and SUN5BJK drawer-style jackets, which were sized for Sunstone's older 28", 34" and 42" grills and are no longer sold. Sunstone lists only the SUNJK jackets for its Ruby grills.
The jacket changes the hole you cut in the island. A Ruby 36" RUBY4B on its own needs a 33-1/2" x 22" x 10" cutout; with the SUNJK40 the island opening becomes 38-3/4" x 24-1/4" x 13", and the grill drops into the jacket's 34" x 22" sleeve. Frame to the jacket cutout in the table above, not to the grill's cutout.
Sunstone's Ruby Series manual asks for 24" of clearance from combustible materials in any direction of the grill. If any combustible material is within that 24", the manual calls for a heat barrier such as a grill jacket, or non-combustible material such as brick, cement board or metal. The manual also states that the 24" clearance under the countertop to combustible construction can be modified by use of an insulated jacket. Follow your grill's installation manual and local code, and have a licensed professional connect the gas.

Fast shipping and exactly what I needed
100% as advertised. The cover fit perfectly, looks great and was delivered quickly. Highly recommend....
I absolutely love my Coyote gas grill! The quality is excellent, it looks beautiful, and I’m very happy with my purchase.
I also want to give a special thank you to Ryan at Northwoods Grills. He was incredibly helpful from the very beginning. Before my grill even arrived, he took the time to help me with measurements and answered all of my questions to make sure everything would fit properly. He was always very attentive, patient, friendly, and easy to communicate with. His customer service really made a difference and made the whole experience so much easier for me.
It’s not often that you receive this level of personal attention and customer service. I truly appreciate all of Ryan’s help and would absolutely recommend Northwoods Grills. Great product and outstanding customer service!
Best pricing available for the product (checked all other on line retailers), and Ryan provided excellent responsiveness during the sales process. Loved dealing directly with the owner vs a sales person.
Delivery was completed within a week of the order and Ryan stayed in touch with consistent follow-up to ensure the products met my expectations.
Will recommend to friends / others looking for a high-end built in grill and matching cabinets.
Great experience with Northwood Grills! I purchased a hood from them and it was delivered quickly and exactly as expected. Ryan was great to work with—helpful, responsive, and made the whole process easy. Highly recommend!
Good sink. Came with all parts as described.
Excellent service and fast shipping!
Don’t know how i ever cooked without this before. Love the char this locks in the meat every time. May add a second one to the other end of the grill.
Great quality.
I was caught in a bind with a DIFFERENT provider, and Ryan was able to get me exactly what I needed, he reached out to the manufacturer for me to confirm specs and had my shipment mailed out same day. If you’re in the market for any outdoor kitchen needs, look no further than Northwoods!
Great service, grill came within a week.
Wouldn’t order from anyone else!
