## 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.

### ⭐⭐⭐⭐ Works great if it closes completely
*by D***D on August 30, 2022*

I purchased two of these to place on the "Y" adapter at the input of my 2hp dust collector, one to my table saw and the other to move between band saw and other tools. One of these closes completely, but the other won't close completely so the suction to the table saw is diminished to where the overhead dust collection isn't effective. I've tried to clean out the channels of any possible debris with no success. The other is fine, but I'm going to have to replace the one that won't shut all the way.
