P7 structural ENGINEERS Attachment Devices: The Flush-mount span tables have been grouped into sets of attachment devices called "Bins", which are presented in the table below. To use this table, find the attachment device to be used in the list below, then read across to determine which bin the attachment is in. The spans may then be determined from the table with the corresponding Bin number. Note: Side load direction is parallel to rafter.

The lowest load value in each Bin (bold value) is used for calculation of the corresponding span table. t Seam clamp load values are the lower of the racking system capacity, clamp slip strength, and seam rupture; based on testing performed with the clamp installed on representative panels of both 24ga steel and .032" (20ga) aluminum. Installation on thicker/stronger panels is permitted. Fastening or attachment of standing seam roof panels to the roof structure has not been evaluated. * In order to reduce the chance for breaking roof tiles, SnapNrack recommends limiting downforce reaction load of the tile hook devices in Bin 7 to a maximum of 333 Ib. 1478 Stone Point Drive, Suite 190, Roseville, CA 95661 916.961.3960 916.961.3965 www.pzse.com 3/923
