There are several different types of connectors used to supply power from a tow vehicle's electrical system to a trailer's wiring system. Some trailers only need the bare essentials -- running lights, brake lights and turn signals -- while others require a connection for reverse lights, electric brakes and auxiliary power. With connectors ranging from simple to complex, it may be the case that the connection between your vehicle and your trailer is not a perfect match. For example, your truck may be equipped with a 6-way round socket, but your trailer may have a 4-way flat plug. For this very common problem, CURT offers a quick and simple solution in the form of an electrical adapter. An adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and vehicle socket. It easily plugs in your vehicle's electrical socket and usually requires no additional wiring. CURT offers an array of adapters to accommodate most types of plugs and sockets, including 4-way flat, 4-way round, 5-way flat, 6-way round, 7-way RV blades and more. This electrical adapter is designed to adapt a 7-way round vehicle socket to fit a 4-way flat trailer plug. It is constructed from quality plastic and requires no splicing. All CURT wiring and electrical products come with a one-year limited warranty to give you the assurance you need to tow with confidence.

Nice cotton summer shorts with a touch of linen
Color: Coffee, Size: Medium, Color: Coffee, Size: Medium
These are a nice addition to my summer short wardrobe. They add a different look and texture than most of my shorts that are cotton. The addition of linen adds a nice texture to them and you can tell they are visibly unique. I ordered these in a medium and I think they are true to size. The have an elastic top instead of a button/zipper. I'm o.k. with it and they are nice to just throw on. I'm not a fan of the string around the waist. My first picture has it hanging down and I quickly removed it...not needed with the elastic band holding up the shorts. I guess it could be a fashion statement if you wanted it to be. The shorts are very light weight and I can see using them in the hotter months that are approaching. Price point is great!

Comfortable shorts!
Color: Black, Size: Large
I ordered these because I wanted some lightweight comfortable shorts for the summer that were now gym shorts. These are very comfortable shorts. Lightweight cotton material that is not stretchy and it breathes well. The size fits exactly as expected according to the measurements. They also have an elastic waistband with drawstring, but also have a button and zipper, which I found odd, but don’t hate. These shorts have two big pockets in the front, large enough for keys and a cell phone. Deep enough to put your entire hand in. The single back pocket is perfect sized for a wallet, and it has a button that secures the pocket, so no losing the wallet in the movie theater or restaurant. The color is a true black, which I’m sure will fade in the future after many washes, but for now, it is dark and black, not like some that look more navy blue than black. The stitching is also done well. These are probably my new favorite pair of shorts that are comfy able enough to wear around the house when just lounging, but also nice enough to wear out to dinner. Well worth the price, will probably buy another pair in a different color soon.

Top-tier quality and fit
Color: Khaki, Size: Large
I'm really impressed with the fit of this shirt it’s true to size and has a great slim-fit cut. The embroidery and fabric quality are excellent, making it look much more expensive than it is. Perfect for any occasion where you want to stand out.
