Today, we are going to take a look at the Optronics 4 way and 5 way Flat Trailer Harness Plug Protector. Now this is going to be a quick and easy way to protect the four or five pole wiring on your trailer. A lot of times those can get banged around especially if you are using them for a long time or they're in frequent use.This is just going to go over our bare terminals on that trailer end wiring and then it's also going to have a small plastic post that is going to fit into the open port for our ground on our wiring. So here we have a four pole. This also, again, works with five pole, it just has the extra terminal on the one side which our plug is built for and it just matches right up. Fits inside there, fits really snug and then you would just have this attached to say the coupler on your trailer or maybe the tongue, just anywhere where you would want this wiring to be secured and out of the way.This is going to keep any debris from building up inside those terminals on your wiring or any water build up or anything like that.
And it's going to keep that wiring from getting corroded or kind of gunked up and it's also going to keep it from getting banged around on the ground or impacted with anything. It's just going to keep it nice and up and out of the way.Now this does not come with any hardware to get that attached so you will have to pick up a self tapping screw or whatever hardware you'd like to use, maybe a nut and a bolt but you will have to provide that on you own. The mounting hole is going to be about 3/16th of an inch in diameter, overall the connector is going to be about an inch and a half wide by about an inch and a quarter tall and at the widest point where it sort of bows out for our mounting location, that's going to be about half an inch. So it's really going to be about the same size as the connector on your wiring. It's pretty comparable there.All in all, it's just going to be quick and easy way to improve the longevity of your wiring on your trailer and keep everything working as it should.
It's not a bad idea to maybe put a little bit of dialectic grease in those terminals so that it'll keep the grease on your plug as well. If you don't have any of that, we do sell dialectic grease here at Etrailer.com if you want to pick some up.And that's going to do it for our look at the Optronics 4 and 5 way Flat Trailer Harness Plug Protector.

Attached this to my trailer and keeps plug protected and up off the ground.
As always, excellent service and products! Never had a bad ordering experience with etrailer and I highly recommend them for both friendly and prompt service and quality of products sold. They are my go to company for trailer needs!
should come standard on all trailers excellent product.
Working great to keep the connector off the ground and clean.
Its a fine product, I wish they had separate 4 plug and five plug protectors because My plug has a built on partial cover rather than 4 bare prongs like in the vide so I have to modify my plug a bit to work with this which if it were specific to 4 way I would not have that problem. Price is a bit steep as this comes with no mounting hardware. Its understandable that it has no hardware because everyone has a different situation and preference. I use 12-24 stainless nut and bolt to attach to my trailer in a spot that is out of the sun etc.
keep the connector plugs clean. i also used a small amount of WD-40 to help keep the rust down over the winter
best item to keep that connector clean should have had it long time ago
Again, just what I ordered
Product was great, only thing was the hubcaps that came with were too big but they provided the right size free of charge
Works great. Protects the pins from getting road grime on them.
Raised area around mount hole provides clearance for plug from mounting surface. It doesn't retain the plug very tightly, and only by the pins. It is for use while trailer is parked. The plug won't just fall out, but brushing the hanging pigtail can pull it. Be sure to seat the plug completely.
Great product, keeps pins clean and corrosion free.
When you mount this item it needs a spacer or it will not work. Like this item
Sierra K - 06/02/2021works great.
Works great keeps plug clean and in pla ce
Great service and all items fit just as it should. I will be a customer for life! Thank you
Works great and as expected.
This part was what I needed and could not find except from etrailer.
I had lost my old cover. This product fit perfect and it arrived quickly. It keeps dirt out of the contacts. The hole allows you to put a cable to hold it to vehicle so when you take it off you don’t loose it.
Good tight fit. I use the hole to run a plastic cable tie through to fasten the cap back onto the harness. This way it will never get separated and lost.
Looks great
Great way to store your plug. Keeps it clean
I ordered several trailer accessories. all of them were true to the website pic and description. all items fit perfectly and serve their intended purpose. Just perfect!!!
Fits my 5 plug (trailer end) perfect. Hard to find !
