Unirac offers three methods of attaching solar modules to Unirac rail systems:
Top Mount Clamps - Are preferred when rails are mounted flush with the roof, or when access behind the solar modules is limited. Top mount clamps are selected to match the thickness of the solar module frame being mounted to the rail.
Bottom Mount Clips - Can be used with any framed module where the frame of the module has mounting holes along the underside. Bottom mount clips lock into either side of SolarMount Standard or HD rails, then bolt to the module.
Shared Rail Junction Plates - Are used with framed modules and SolarMount Standard or HD rails to allow the solar modules to share a rail.
