Mounting Block for Metal Siding

[Wardster]

Wondering if anyone knows where I can get a mounting block that will fit flush against the ribbed metal siding, so I can properly mount the outside cover for my bathroom exhaust fan. I checked the accessory catalog from the manufacturer and I am not finding anything. If nothing exists, then I am wondering how you dealt with wall penetrations through the ribbed metal siding. Pictures would be great.

Thanks in advance - Tim

That should be easy enough to make. Thanks for pointing me in the right direction.

I did not look at the thread. I have read it previously, and do not recall if it was mentioned. But I'll suggest that you use treated wood to build the spacer.

even tho treated seems like a good idea ive seen it eat a hole in the panel. Id rather replace a block than replace the panel.

Good point cyamaha2007, I did not think about the current type of treated lumber.


Scratch my previous post.

It's hell getting old.

If you can run some standard metal or pvc pipe for the exhaust tube then you can use a flexible roof pipe flashing that will mold to the ribbing and can be cut to fit the tube. Master Flash makes one but both Lowes and HD sell similar items. I used one for the exhaust vent out the side of my metal building as well as a plumbing vent out the side.

I did use treated lumber for the frame in the chimney pics linked to above. However, I primed them with Kilz and painted them with Rustoleoum prior to installing them, and when they were installed they have a layer of mastic tape between them and the metal, the holes were predrilled to preventing splitting, and the edges are sealed with GE Silicone II. The long screws I used to hold it all together were all coated.

Hopefully it will last longer than myself.
