Review: Works great - Purchased for block heater and works flawlessly. Covers nicely 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. ## Features - Package Dimensions: 2.895 cms (L) x 10.210 cms (W) x 12.903 cms (H) - Product Type: Auto Part - Package Quantity: 1 - Country Of Origin: United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004BTBT4M | | Best Sellers Rank | #29,178 in Automotive ( See Top 100 in Automotive ) #291 in Automotive Replacement Engines & Engine Parts | | Brand | Zerostart | | Customer Reviews | 4.5 4.5 out of 5 stars (1,195) | | Date First Available | July 2, 2009 | | Exterior | Machined | | Is Discontinued By Manufacturer | No | | Item Weight | 0.01 ounces | | Item model number | 3600012 | | Manufacturer | Zerostart | | Manufacturer Part Number | 3600012 | | Model | Protector for 120-Volt Plugs | | Product Dimensions | 0.75 x 4 x 14 inches | ## Images ![3600012 Block Heater and Extension Cord Outdoor Plug Cover, 120 Volt 3 Prong Plug Protector | Black - Image 1](https://m.media-amazon.com/images/I/51LJKU0UuqL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by S***Y on May 1, 2026* Purchased for block heater and works flawlessly.

It's been on for about a month and keeps the grit, rain, snow and road dirt off the plug. Yeah it's pricey for one item BUT it stays where you put it and fits snugly.
