Features to know about

Maximize Electrical Efficiency: Zinc Die-Cast Construction with Solid Brass Pins

Ensuring reliable and consistent power flow is crucial, especially in demanding conditions. The Pollak Heavy-Duty 7-Pole, Round Pin Trailer Wiring Socket features a zinc die-cast body and floating solid brass pins. This combination not only provides a durable design but also ensures easy alignment with maximum pin contact, minimizing voltage drop. These quality materials are perfect for tackling everyday wear and tear, keeping your connection strong season after season.

Protect Your Connection from Corrosion: Dielectric Grease Coating

Rust and corrosion are common enemies for electrical connections exposed to the elements. This trailer wiring socket includes a dielectric grease coating, shielding against corrosion and resistance, and enhancing its longevity. Whether you're towing a semi or a simple trailer, this protection layer keeps your connections in top shape.

Versatile Wiring Compatibility: Accepts a Wide Range of Wire Gauges

Finding a socket that accommodates various wire gauges can be a hassle. With the Pollak 7-Pole Socket, there's no need to worry—it's crafted to accept a wide range of gauges, from #16 to #8 for ground wires, ensuring compatibility with diverse wiring setups. This flexibility makes it the ideal choice for both small and large vehicles, providing customization options for whatever you're towing.

Stand Up to the Elements: Slant-Mounted with Built-In Drain Slot

The unpredictability of the weather should never interrupt your towing plans. This socket features a unique slant-mounted design with a built-in drain slot to efficiently rid accumulated moisture from your socket housing. An extended bottom lip further ensures the plug support remains uncompromised, letting you focus on the road ahead regardless of the weather.

Whether you're swapping in or out between towing setups, this socket ensures a seamless transition, making it a versatile addition to your towing arsenal.

I hook and unhook my trailer about twice a day as I need my truck for hauling stone and dirt. I have put this through the ringer. Still good as new...Happy customer



by:

I would highly recommend this. It is heavy duty and quality built. A great value for the money



by:

Excellent product! - have, over only a few years, steadily worked my way through progressively more durable trailer cable sockets. The last one was the Hopkins heavy-duty, or something to that effect. The plastic casing on it broke within three months. I'm really looking forward to putting these to the test - I'm a farrier - I pull a trailer every day; the traffic in this area means that I must rely on excellent contact between vehicle/trailer for turn / brake signals and functioning trailer brakes. Nothing less. These sockets are heavy, all-metal (zinc-coated - road salt shouldn't be a problem), with few / no seams. When the trailer end is plugged into the truck receiver - it's a nice tight fit, with no movement: it's locked in. There are only two drawbacks for the homeowner who is looking for the do-it-yourself package: if you are looking for a metal bracket that bolts underneath the truck bumper and holds this part - there isn't any. And no bolts, either. I don't know if they sell them for these - I didn't check. I simply manufactured my own. So far, I'm delighted with the product.



by:

I ordered the 7 pole socket (PK11720) and the rubber boot for it. (PK11761) Also a trailer end plug (PK11700) to fit into the socket. The items arrived on the exact estimated arrival date that I was given on the day of ordering.
Wiring the plug and the socket was very easy. Each terminal has a small screw that holds the end of the wire in place. It is a simple matter of threading the screw out, putting the wire in the hole, and then tightening the screw onto the wire.
The boot fits snugly onto the back of the socket.
I used these parts to repair the power cable assembly to a truck mounted forklift. The parts are exactly what was needed to replace what had been damaged. The quality is good and the prices are excellent. I will use etrailer.com in the future when I need related items. I am very pleased.

It is working out very nicely, really glad I bought it!



by:

Bought to replace a 12 year old Pollak identical connector that I removed and could not re-use due to wire connections on the back being corroded (road salt area). The 12 year old connector worked fine except the flip up cover was a bit stiff. The 12 year old connector was also made in USA. The new connector I just received is made in China. From the price, I had hoped it was still made in USA. It seems that most of the time I am disappointed with the newer imported China versions of products once manufactured in USA. So my expectations for this product to have a long life are not very high.



by:

Well I have not installed it yet, but it is marked for each trailer wire by color, matching much earlier models. Did not come with mounting screws and nuts, but not a big deal.



by:

I could not find this style or make trailer plug in my local auto parts store. I got tired of trying to find it so I ordered it on line. etrailer was convenient and less expensive than any other website.



by:

Quality product arrived on time. Will make future purchases with etrailer.com

Performed as expected to date.



by:

The metal body and good quality pins and connections make this one the only one for a professional job.
Remember if you use dielectric grease and the rubber boot you'll never have corrosion in your connections . Dissimilar metals and weather are a bad combination.



by:

For me, and probably you, etrailer.com is a great place to shop/buy quality products. They give great follow up after ordering and fast shipping @ a fair price. I believe their service & pricing is unbeatable. I do shop for bargains & etrailer is @ the top of my list.



by:

Excellent product! I bought this to replace the old, brittle, and broken plastic trailer connector on my 1973 aluminum camper. The plastic one stood out against the aluminum which I didn't like. So, I'm excited how this will blend in and look more natural. Besides aesthetics, this very sturdy and ruggedly built. It will clearly outlast the camper, no doubt. Will definitely buy again if I find myself with a different camper in the future.



by:

Etrailer web site was easy to work with and outstanding communication with your orders. Package was also delivered earlier than expected. I would rank etrailer as A+



by:

Great construction of the product, durable enough to withstand harsh working conditions and "operators" I am using that term lightly due to the mishaps that occur on a regular basis at my location.



by:

Best 7 pole connector out there!!!!

This trailer lighting socket is excellent quality, and super fast shipping

Very fast service AGAIN! Always my first choice when shopping for trailer parts.

Great Product. Just remember to order the boot for the back of it separate.

Great, Fast, Knowledgable and Polite Service. Return policy is also terrific no questions asked. I will use e trailer again. Thank You

This connector is really nice and with the screw tightening wire connections that are on it, it will make the wiring a lot easier to do.

  • How To Find Cold Side Of Stop Light Switch On Vehicle For Brake Controller Installation
    Normally you can find the brake light switch under the dashboard at the top of the brake pedal. There could be a number of wires attached to the switch so you can use a tester like part # PTW2993 to test the wires. Since the auto manufacturers can use different color wires it is always best to use a tester and check the wires for function and not color. You would need to find the wire that only shows power when the brake pedal is pressed. That would be the wore that gets attached to the...

  • What Color Wires Go Where On Trailer 7 Way Harness?
    I linked an faq with wiring diagrams to show the standard colors for most 7 way trailer harnesses. That said, color is not always best to go by, so you'll want to take a circuit tester # PTW2993 and test each function before wiring the harness to your trailer. If you can tell me which vehicle you have or send in a photo, I can better help you.

  • Towing a Trailer with Electric Brakes with a Semi Tractor with Air Brakes
    To tow your trailer that uses an RV style 7-way blade style connector with your semi that has a 7-pin connector, you need to construct an adapter that will also combine the brake signal into the right and left directional signal pins. This can be done by using a female 7-pin socket # PK11720 to accept the plug from the semi, a tail light converter # 119178 and a female 7-way RV blade-style socket # PK12-707E. The converter would be wired in between both sockets to combine the brake light...

    It sounds like your 2005 Ford Super Duty was outfitted with the 7-way blade system which is the most common in the market today. To adapt your 7-way blade to a 7-pole round for your trailer, I recommend the Pollack # PK12728. This 7-pole connector is prewired to simply plug into your truck's 7-way plug. It has the # PK11720 connector you referenced but is pre-wired like you are desiring. A great mounting bracket for the # PK12728 is the # PK11771. I have linked all the above mentioned...

  • Adapting 7-Way Round Pin on Mack Semi-Tractor to 7-Way Blade Style RV Connector
    A 7-pin connector on a Mack Tractor like you described would function a bit differently than a 7-way blade-style RV connector. The difference is the right and left turn pins on the 7-way blade also carry the signal for the brake lamps while on the 7-pin, one pin carries the right turn lamp, one the left and another carries the brake lamp signal. In order to combine those three signals onto two circuits, you'll need a taillight converter. There isn't an off-the-shelf adapter that'll do...

    If you use the 7-way that is used for commercial/industrial/agricultural application like # PK11720 or the RV/standard 7-way like # HM47210 you will need to utilize the same location. The reverse signal should be connected to the center location of either application. You will simply need to make sure your wiring corresponds with the function locations. I've attached a photo to assist. For a 7-pin that normally does not have a reverse light, that means utilizing the auxiliary in the...

  • Installation Procedure and Recommended Brake Controller for 2016 Jeep Wrangler Unlimited
    I'd recommend you go with a proportional style controller like the Tekonsha Prodigy P2, part # 90885. A proportional controller has an internal sensor that determines how quickly the tow vehicle is braking and will send the appropriate amount of voltage to the trailer brakes so the trailer and tow vehicle stop at the same rate. This leads to safer, more predictable braking action. To install the controller, you'll need our Brake Controller Installation Kit, part # ETBC7. The kit contains...

  • Is it Better to Switch to a 7-Way Blade Style Trailer Connector Over a 7-Way Round Pin

However, if you already have a 7-Way round connector you can just use an adapter to go to a 7-Way blade style when needed. You can use # HM47425. If you want to go ahead and switch from the 7-Way round to the blade style I recommend a multi-tow connector, # HM48470, which has a 7-Way blade style, a 5-Way flat, and 4-Way flat.
