Observe the following guidelines:1. All blocking, hangers, rim boards and rim joists at the end supports of the TJI® joists must be completely installed and properly nailed.2. Laterial strength, like braced end wall or an existing deck, must be established at the ends of the bay. This can also beaccomplished by a temporary or permanent deck (sheathing) fastened to the first 4 feet of joists at the end of the bay.3. Safety bracing of 1x4 (minimum) must be nailed to a braced end wall or sheathed area (as in note 2) and to each joist.Without this bracing, buckling sideways or rollover is highly probable under light construction loads - such as a worker orone layer of unnailed sheathing.5. Ends of cantilevers require safety bracing on both the top and bottom flanges.6. The flanges must remain straight within 1/2" from true alignment.4. Sheathing must be completely attached to each TJI® joist before additional loads can be placed on the system.WARNING NOTES:WARNINGJoists are unstable until braced laterallyBracing Includes:BlockingHangersSheathingRim BoardStrut LinesRim JoistDO NOT stack buildingmaterials on unsheathedjoists.
