Featuring FLASHLOC Technology, SOLOBOX saves you time and labor on the roof by limiting shingle cutting and prying nails on attic runs. For rail-mounted applications, SOLOBOX mounts quickly to Unirac’s J-Box Mounting Bracket and has a low-profile design to sit under the panels (where permitted). The box itself can support 2 attic pass-throughs and features a hinging lid, a single captive screw, pre-drilled weep holes, and an option for a pre-assembled din rail.
