ICC Excel Fastening Scheme

[bdahlmann]

Hello,
Hoping for some assistance from any experienced ICC Excel installers.

Specifically, I am in process of an installation an am confused by the directions for fastening sections.

The manual directs aligning the seams and fastening though the piloted holes. My issue is that the holes are not visible in the slot unless tremendous downward compression is applied. Even then, the pilot holes are barely visible.

The ICC video on YouTube describes fasting as ”Zip, Zip, Zip”. This is not that.

Are the pilot holes required for correct mating or, is fully seated and field derived fastener holes (into the reinforced section) the standard?

If the former is required, is there a method to achieve the required compression to align the pilot holes?

Slam it down hard or use a 2x4 block to protect the end and try and hammer tighter. If the holes are still not fully aligned, can you use a drill to slightly enlarge the outer hole?

Mine were next to impossible to line up as the lining needs to really be pushed down tight. I was wishing they were twist on like other brands. I did my best but doing it on top of a slanted roof and not falling off. For a highly rated pipe they should go together easier.
