If you plan a ceiling mounting, you just need to align the tracks properly.If you plan a wall mounting, you can use our joining brackets SU5241 or SU5242 (only compatible with our SLID’UP 160, SLID’UP 170 and SLID’UP 190 series).Depending on your project, we have connectable tracks to make longer tracks (more than 8 feet): SLID’UP 1000 & SLID’UP 1100.
