  • NICE

  • The purpose of the inspection hole is to help you determine which way your rafters and purlins are running. (direction)...

    Armed with knowledge the Roof crews can safely walk to were they need to go to cut their heat hole. Along the way putting in small smoke path indicators to help you determine the fire intensity inside...

  • K12!!!

  • The inspection hole is def the most pointless thing next to a kerf cut

  • @ekolarick How do you find rafter direction then? If you don't know where the rafters are going, how to do get as close to the fire as possible to vent? (I'm talking about commercial blds as rafters for homes always run top to bottom)

  • what if you get a tar roof and it gums up the blade to the point it stops.

  • then you would get a different saw but the chances of that arent high
