Here's another company with a great name that leaves no doubt as to what their specialty is and where they're located. Since 1973, Dallas Avionics has distributed aircraft test equipment, electronics, installation supplies and yes, avionics. They carry everything from annunciator control units and ELTs to terminal splices and wire cutting machines. We offer their 500U Custom Loop Box. If you require additional information about this product or if you're looking for something that you don't see here on our website (hard to believe, but it happens on rare occasions), you can give our customer service wizards a call and they'll be happy to assist you. At SkyGeek.com, there's a wealth of knowledge about everything to do with aircraft maintenance, tools, parts and supplies, so speak to our resident geeks and test their knowledge.
