## Product's reviews:
- 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!!!
- Durable and high quality - I bought a second one to keep as a spare, but the first one still hasn’t shown any signs of wear. Seems like a quality part.
- Service manager - on time.. great company thanks john gorth
- Service - qUICK SERVICE ON THIS ORDER
