## Questions & Answers

**Q: Can anyone tell me the actual  outside diameter of the flange on the 4"**
A: I used 4" schedule 40 PVC and it fit snugly on the 4" blast gate.  I also drilled and screwed two sheet metal screws per blast gate (along with silicon sealer)

**Q: Are they both 4" od, or is one size 4"id for dc machine port?**
A: No,
They are 3 11/16 id and 3 13/16 + 1/32 od.   There is nothing 4" here.

**Q: any suggestions on how to attach this to 4" DWV? The pipe is too large for these.**
A: I didn't hook them up to 4inch. I ran 2 3/4 flex and pvc.  Btw...it clogs up with saw dust. I drilled a hole on side opposite the slide with a forsner bit to blow it out. I cover the hole with duct tape.

**Q: The action on the 4" plastic version is very rough / jerky.
Any successful method of smooting the action?
Grease?**
A: I found it varies from one gate to another.  Applying wax from a candle or similar source, helped but did not fully fix the issue.  I just rubbed it on the flat portion that fits in the groove and worked it back and forth.  I would be afraid that grease would trap dust.  I prefer metal gates.
