Jerry:
We have successfully used the DPW EZ-feet on sheet metal, cathedral roofs with TJI rafters. The cathedral roof made it impossible to install blocking. The EZ-feet is supposedly rated to screw solely to roof sheeting. When we first investigated the product, we discovered the fasteners recommended were not properly rated for sheeting thickness ranges. I understand DPW corrected this. Nonetheless, we used the EZ feet and used longer sheet metal screws where the foot landed over the TJI. This way we were not using fasteners quite as large in diameter as a lag and we gained the rating for the screws into sheeting that don’t lie over the rafter.

Does anyone have experience permitting and installing on TJIs? I'm curious if jurisdictions are requiring Structural Engineer stamps. Since the top chord of the beams is only 1 3/8" thick should we be using shorter lag bolts for these installations? It also seems that it would be undesirable to penetrate into the web of the beam. Any advice would be appreciated here. Thank you, Jerry Caldwell
