## Questions & Answers

**Q: Would this work to mount a 4x4 post?**
A: Yes, the hardware will. But you will need longer moldings for your post size.  So when you order, make sure and send the seller a message that you need the moldings cut to your size. They will cut it custom for the same price.

**Q: Do this come in 7×7**
A: I think so

**Q: A 4X4 post is actually 3 1/2X3 1/2, so will the molding work?**
A: The molding has worked beautifully for us.

**Q: would i be able to get these cut to fit a 4"x4" post.**
A: The ones I bought were made for 4x4 posts. My son fastened the metal brackets to the bottom of the post easily without pre-drilling. I held the post level and plumb while he put the screws into the porch floor. The wood trims fits perfectly around the base and completely covers the brackets.
It took less than hour to install two posts and they look great. I would recommend them.
Hope this helps!!
