Review: Running belt was a good product and value for the price. - The running belt construction is very well made. I have used it for about 3 months and experienced no problems. It was also fairly easy to install. Good product and value. Would purchase from this seller again.
Review: Great quality walking belt at a reasonable price. - It seems sturdier than the original belt and fit perfectly. It is a it noisier when walking/running on it, but it's not an issue for me. Ignore the negative reviews as they are reflections of the buyers and not the belt. If it doesn't fit then you send it back. If you are not comfortable working on machines then maybe you should have someone else do the work. Yes the installation required taking much of the machine apart, but it's not too hard if you pay attention to fit and alignment.

## Questions & Answers

**Q: Will this fit a ct5.4???**
A: I don't know, but if it is the same belt I put on my T-101, you can't go wrong. It is a lot better then the belt that came on my treadmill.

**Q: Will this fit  for Horizon T81?**
A: No, it will not fit. To be able to accurately search for your part, you need the specific model number for your treadmill.  Many model numbers exist for the same model name, and some of them have different parts.
You can find the model number on a metal plate or sticker located on the treadmill frame near the power cord, on the motor cover, or inside the motor cover.

**Q: Will this replace a belt that is 20 x 114.75 inches?**
A: The listed belt is slightly smaller.  19.5 x 114.5

**Q: Keys fitness model ht95t serial b1037081 would it be fitted? or where can i find one?**
A: I would need the model number. It should start with HRTL or HETL.
