## Questions & Answers

**Q: Can someone be so kind as to please specify what precise size screws (and length..and URL to product if possible?) as well as drill bit size (for pilot holes) you used?**
A: I used size 14x3 (inch) screws. They're probably one of the thickest screws you can use. The thicker it is, the sturdier it'll be. Size 12x3 is a bit smaller but would still work. I recommend at least a 2 1/2 inch long screw. I used 3 inches. Again, the longer the better. Size 14 needs a 1/8 inch pilot hole into the stud. Size 12 needs a 7/64 pilot hole. You can find these screws at any DIY store.

**Q: is this just one piece or two?**
A: One. You would probably want to buy an open ended piece for the other side anyways. Easier to insert and remove the 2x4

**Q: What type of metal are these?**
A: The description says rolled steel.  They are quite substantial.  We use on the inside of our basement door with 2x4s, so i cannot attest to whether they are rust-proof if used outdoors.  They accomplish what we wanted.

**Q: is there a brace made to go on top of the narrow side of a 2 x 4 insted of this one?**
A: Yes, and you can find them on the Internet in the same place that the captive types are found.
