Oh just because the L foot was bad mouthed on the list earlier, although no one had ever had a reported problem, even with installs 20 years old. I think its actually your new product line of cool flashed mounts that made us all feel inadequate with the venerable L foot.
Glad to hear about the change to the heavier duty hanger bolt.

Thanks,

Ray

We changes from a stainless steel hanger bolt to a Galv. hanger bolt because of customer input about 4 months ago. At risk of sticking my neck out can you define why you call it the dreaded L foot?

We used a lag stud assembly from Unirac, with the dreaded L foot at the top of the corrugated ridge, & plenty of pooky under. The driver tool for the stud wasn't very useful, and because the stud was stainless we had a hard time driving it all the way in, without over torquing. I'd use a larger diameter, non stainless stud next time.

THis was on a horse shed, I wouldn't mess with the thin corrugated roofing at all on a residence. Its so thin it bends just walking on it. There is some heavier gauge corrugated roofing that is nice.

My rule, is if the roof is already questionable, I won't touch it if its a residence.

Wrenches,



For those of you in the opinion of using standoffs instead of L-feet,

what do you do on corrugated metal roofs? I'm seeing a lot of these in

both residential and commercial buildings.



Thanks in advance for any suggestions.
