## Questions & Answers

**Q: The height on one side is 7/16". What is the height on the other side?**
A: I have used these several times. The “thicker” edge snaps into the outer edge of an aluminum in swing threshold. This edge is close to 5/8” , the specification uses .6”. The curved or finish edge is about 7/16”. You must provide support under this extender. If will not support any weight if not supported from below.

**Q: What can I use to cut? My threshold is 32" instead of 36".**
A: You can use a hack saw or sawzall.  Any metal cutting tool will work fine

**Q: Does this fit therma tru doors?**
A: If you are talking about a sliding door, no. It fits any door that does not have a prebuilt threshold

**Q: Will this fit “feather river” brand door?**
A: The extensions are standardized....yes, all brands fit

## Customer Reviews

### ⭐⭐⭐⭐⭐ Storm door install
*by R***. on September 17, 2025*

Extension was easy to install and worked well with storm door installs on log cabin. I did have to rip a board to support but that was due to the unique way they trim log cabins. I'm sure installing on a regular door would be simple.

### ⭐⭐⭐⭐⭐ Fits perfectly
*by M***M on September 23, 2025*

Fits Frost King aluminum and oak threshold TAOC36A perfectly

### ⭐⭐⭐⭐⭐ 2” Threshold Extension
*by D***. on August 19, 2025*

This is exactly what I needed to extend my front door threshold that otherwise was part of a special order for the door frame.
