I ordered a 2nd 55" Makita Guide Rail and the TSO Connectors. They worked great but I found when taking down sheet goods, I was constantly assembling and Disassembling the connected tracks. I decided the "Heck with that" and purchased a 118" Makita Guide Rail for us with my TS-55. If you are taking a lot of sheet goods down, buy the larger guide rail and save yourself some time. But again, the TSO Guide Rail Connectors work great. I use FastCap "TRACK RACK" to mount it to my garage rail (You need 3 Track Racks for the 118" Guide rail
