System Components
To build a fully functional SFM Infinity system, the following components are required.

SFM Butyl Attachment
Supports both rafter and direct-to-deck installations, securing the 2″ MICRORAIL and 8″ ATTACHED SPLICE to the roof. A pre-applied butyl pad eliminates the need for sealants or metal flashing, while north–south adjustment simplifies alignment. An integrated stop helps prevent the MICRORAIL or ATTACHED SPLICE from sliding on steep roof pitches. Includes two rafter screws; additional decking screws and butyl pads or shims are sold separately.

trimrail
Provides structural support, module alignment, and a clean front-edge finish for the first row of a solar array. It securely captures module edges, accommodating a wide range of module thicknesses from 30 mm to 40 mm. 72” long. Trim end caps available, sold separately.
