I'm looking for an electrode w/collector box for a brinkmann 2600 pro BBQ but I don't see one listed.

Unfortunately, we had to remove all electrodes from our Brinkmann 2600 listing. Different customers reported differing sizes, so we weren't able to confirm one single fit. We've had customers use SKUs IG16, IG29, IG23, and BMBR1 in that model. If you have the original channel electrode, measure it. Usually, the closest in dimension will work. However, be sure to order a part that will fit in between the burners mounted in your grill. It would be good to know that measurement as well. Give us a call if you need assistance 678-272-2451. PS - if everything else works in your grill, don't toss it just because the ignition system doesn't work. You can use a long-stemmed ignitor to light the burners safely.
