## Product's reviews:
- Sprocket lm - Good quality product, arrived on time, will continue to buy from this company
- High quality - strong material
- 21 tooth 12 dp spur gear - The 21 tooth 12 DP gear I bought arrived very quickly.
It was exactly what I needed to fix my RV slide out.
I had to machine it to fit, but I knew that when I ordered it.
VERY SATISFIED!!!
- Service manager - on time.. great company thanks john gorth
