No more guessing which couplers fit

When you're building an outdoor kitchen, the last thing you need is a trip to the hardware store where the staff can't tell a 3/8" fitting from a 5/8" one. This curated kit eliminates the guesswork by bundling both sizes with the exact MC-5 communication cable your DIY 4th Gen 24K or 36K unit requires. At Grill Island, we test what we sell — if we wouldn't use it in our own backyard, we don't list it. Every component in this kit is vetted for proper fit and reliable signal transfer, so your system works right the first time.

75 feet of clean, reliable communication

75 feet of clean, reliable communication

The included MC-5 cable gives you 75 feet of length to route your signal cleanly across an outdoor kitchen setup without signal loss or interference. Whether your unit sits at the far end of a countertop run or your control panel is mounted at a distance, this cable handles the span without stretching or degrading performance. Paired with both 3/8" and 5/8" couplers, this kit ensures you have the right fittings for whatever configuration your 4th Gen build demands. It's a straightforward investment in making sure every part of your system talks to each other without hiccups.

Built for 4th Gen 24K and 36K units

Built for 4th Gen 24K and 36K units

Compatibility shouldn't be a puzzle. This kit is specifically assembled for DIY 4th Generation 24K and 36K units, so you're not cross-referencing part numbers or hoping the specs align. The 3/8" and 5/8" couplers cover the two most common fitting sizes these units require, and the MC-5 cable matches the communication standard they depend on. At Grill Island, we believe buying components for your outdoor kitchen should feel as straightforward as firing up the grill — not like studying for an exam. This kit delivers that simplicity.

“Saved me a second trip to the hardware store. Both coupler sizes were exactly what my 4th Gen 36K needed, and the 75-foot cable was more than enough for my run. Straightforward kit that just works.”
