Review: Works as intended. - Keeps moisture and road dirt off connection. Works as intended. Has not fallen off.
Review: Perfect on my extension cord - Unlike most others it seems, I am NOT using this protector on my truck cord. Yes, I do own a new 2024 Ram 3500 with a Cummins HO engine, however, that is not why I needed this product. I have an outdoor golf cage where I am using a junction box to power an overhead light as well as a projector. I have an desertcart Basics extension cord (https://www.desertcart.com/dp/B00OS7ETIA?psc=1&ref=ppx_yo2ov_dt_b_product_details) plugged into the junction box that in turn gets plugged into the house. I wanted to ensure that the extension cord is also waterproof, and this little plug/protector works perfectly. The fit is tight and precise & I have zero worries about water leaking in.

## Questions & Answers

**Q: Can this be used when the other end is plugged into outlet...as a precaution**
A: This is only for the male cord end.  This cab covers the end that plugs into the outlet.

**Q: Will this fit over the 3-prong end of an extension cord?**
A: This plug cap is designed to cover the end. It will depend on if your cord shape matches the shape of the end of the cap. I used the particulary for a cord protector on a engine block heater. It fits, but not as snug as I'd had hoped.

**Q: Do they make one for 30 amp prongs and 50 amp prongs**
A: This thing is completely plastic it’s nothing to do with how many amps they draw. This cap is for your standard house outlet three prong design.  It wouldn’t matter if a thousand amps were used when it’s not in place. No current flows when the cap is on

**Q: Will this keep my pump sump male plug protected until I plug it when is need it?**
A: This will work as a protective cover for most 120V 3-prong male plugs.

### ⭐⭐⭐⭐ Exact Fit.
*by G***R on March 2, 2022*

Got this to cover and protect the Block Heater Plug on my JD Gator. It fit really tight so that it stays on and keeps the mud off the plug. I thought it was a bit on the expensive side, but if it keeps the plug from becoming mud covered and then have the mud freeze, I guess it will be worth it.
