## Questions & Answers

**Q: will this work on connecting a 6" cast iron to a 4" clay sewer line??**
A: No, the 4" side on the P1056-64 is a nominal 4.46" inside diameter according to Fernco so it too small for 4" clay. The Fernco 1002-46 is designed for 6" PVC/cast iron to 4" clay and according to Fernco.com has a 6.39" by 5.18" inside diameter. Haven't worked with clay pipe but according to the sizing information from the Fernco site, any adapter with a clay connection requires that side of the adapter to be sized just for clay. Hope this helps.

**Q: Will this work on connecting a 6" dsw sch 40 pvc pipe to a sdr 35 4" pipe?**
A: It will work but because sdr 35 is thinner wall than sch 40 be careful not to over tighten the connection to the 35.

**Q: What are the inner diameter dimensions?**
A: Its difficult to measure as it is flexible and not perfectly round when not installed on a pipe.  As close as I can get the inside diameters are 4 1/2 and 6 1/2 inches.  Fits 4 inch schedule 40 PVC and the top fitting on a IBC container which is what I used it for.

**Q: 12"coupling reduce to 6"**
A: No. Mine fit loosely on an 8" to 6".

These 4”x6” runner boots work great. I am using them at the top inlets of a water harvesting system that utilizes 4 inch -pvc pipe schedule 40. The 4 inch end of the boot slips onto the pvc with no problem. The boot comes with two stainless steel clamps that fit each end of it. I used the 6 inch end to secure screen to filter out debris and keep it from entering the system. The boots are durable, the size is accurate, and they are a good value for the money. I would recommend them.
