## Questions & Answers

**Q: What size is the bolt and how long is it?  Thanks.**
A: I measured the bolt at 3/8" threaded diameter with 2 1/4" of threaded length. Since this is not specified in the description and other bolt lengths would work the same, it may be you'd end up with a different bolt length.

**Q: Would this stand up to the abuse of an ATV, as a dry storage tube cap?**
A: I would think so. It’s pretty sturdy

**Q: Will this seal the 31/4" cleanout hole in 4" cast iron sewer line?**
A: This plug properly fits a 4" hole. Mine is in use so I cannot measure it. However, I also purchased the 3" plug and I believe it would be more appropriate. At max, it achieves about 3 1/8 seal. If you wrap enough material around the 3" you might get a more usable product.

**Q: End of RV slinky storage tube is 4.5 " diameter.  When rubber is compressed will this be tight enough to survive vibration of normal travel?**
A: It's meant to hold fast in a firm pipe, like PVC.  I wouldn't recommend it for a hose or pipe with give. The rubber gasket only moves out a little bit when tightened. Maybe you could get a large hose clamp and tighten it down outside your hose after you cover the end with aluminum foil.

### ⭐⭐⭐⭐ Slightly overpriced

Good product, but slightly overpriced

### ⭐⭐⭐⭐⭐ Fantastic

### ⭐⭐⭐⭐⭐ Perfect fit
*by J***S on 20 March 2021*

Bought this to seal off a toilet flange that we are no longer needing. This toilet flange was too hard to remove and at some point we may want to reinstall the toilet. The 4 inch sized one works perfect. A nice tight seal.
