**WARNING** READ AND FOLLOW ALL NOTES ON THIS DRAWING!
**IMPORTANT** FURNISH THIS DRAWING TO ALL CONTRACTORS INCLUDING THE INSTALLERS
Trusses require extreme care in fabricating, handling, shipping, installing and bracing. Refer to and follow the latest edition of BCSI (BuildingComponent Safety Information, by TPI and SBCA) for safety practices prior to performing these functions. Installers shall provide temporarybracing per BCSI. Unless noted otherwise, top chord shall have properly attached structural sheathing and bottom chord shall have a properlyattached rigid ceiling. Locations shown for permanent lateral restraint of webs shall have bracing installed per BCSI sections B3, B7, or B10,as applicable. Apply plates to each face of truss and position as shown above and on the Joint Details, unless noted otherwise. Refer todrawings 160A-Z for standard plate positions.
Alpine, a division of ITW Building Components Group Inc. shall not be responsible for any deviation from this drawing, any failure to build thetruss in conformance with ANSI/TPI 1, or for handling, shipping, installation and bracing of trusses. A seal on this drawing or cover pagelisting this drawing, indicates acceptance of professional engineering responsibility solely for the design shown. The suitability and use of thisdrawing for any structure is the responsibility of the Building Designer per ANSI/TPI 1 Sec.2.
