Pure Excellence
For my Snowplow. Buy 2 for a reason. I tighten up nut to small prong to tight broke. Use the other. Plow works fine. Now old solinoid tired worn out. But yes. This works for a snow way plow. I recommend. Just order 2 more. Just in case. Came same day I ordered. Great price. No local stores do not have any city

Make sure it’s the correct voltage.
Item was just as described. Ordered to a pick-up locker and received 2 days quicker. Installed next day and got my RV slide back in working order.

Poor quality. Terminal broke during installation.
The power terminal sheered off when I was tightening the nut and lock washer. I was tightening it with hand tools and it just broke right off. I guess I will be ordering a different brand.
