Attachment Connections to TJI® Joist Bottom Flange

Occasionally people need to connect items to the ceiling of a room. This means that they are attaching items like bike racks, garage door motors, lights and other items to the bottom flange of the TJI® Joist. It is important that people are aware that only specific items can be hung and the right attachment connections are needed. Technical Bulletin 808 properly specifies the attachments necessary based on the series of TJI® Joist used to meet the design consideration of a maximum allowable bottom flange load of 500 lbs for every 5 feet (250 lbs on each side of flange). Please make sure the joist has been appropriately sized for extra weight imposed. 

Additional discussion for attaching exercise equipment to TJI joists can be found in this article.
