Rails shall be fabricated from 6063-T6 aluminum alloy. Theupper rail shall consist of a structural hollow. Interleave of theupper and lower rails shall accommodate PV module framewallsbetween 1" and 2.5" inches in height. Compression of the railsshall be attained by a 5/16"-18 stainless steel button head boltand a captive threaded insert cold formed onto the lower rail. Anatomy of the CompRail System1 A 5/16" 300 series stainless steel button head bolt is used tocompress the CompRail assembly. Bolt holes are predrilledon 20" centers. Both bolts and washers are available instandard or black oxide finishes to match upper rail coloroptions.2 The upper rail is available in clear or bronze anodize or millfinish aluminum.3 The PV module framewall is held captive between theextended upper rail wings and the lower rail shelves. Thelarge interleave between the two sets of rails can accom-modate PV modules between 1" to 2.25" inches in height. 4 The lower rail is a structural channel fabricated from 6063-T6 aluminum. The channel has an extruded drill startermark on the back surface for drilling attachment points.5 Cold forged threaded inserts are hydraulically pull-formedonto the lower rail creating the compression nut. The largediameter of these cold formed inserts yields superior resis-tance to stripping and pullout.The CompRail ConceptCompRail utilizes a common lower rail that bridges adjacent rowsof PV modules. The modules rest on shelves that extend fromeach side of the lower rail. The modules are held captive by anupper rail that bolts into the lower rail and compresses the PV mod-ules between the two rail sections. Both rails are monolithic andextend the entire length of the row, forming a superior frame thatemploys the continuous PV module framewall to increase the rigid-ity of the entire CompRail racking structure.Due to Sunearth’s policy of continuous improvement, specifications are subject to change without notice.
