Easy-Pull Ring Handles Are Easy to Grip and Pull

Easy Pull

Standard 4-way flat plugs have a small surface area to grip when you are pulling them apart, forcing you to wriggle the plugs back and forth to loosen them. Some users even pull on the wires. This can lead to broken terminals or ripped wiring. With the Easy-Pull extension loop adapter, each plug has a large grip ring designed to make disconnecting a snap. Simply slide your finger into the ring and pull the plug away from the opposite plug to disconnect.


Easy Pull Rings

The Easy-Pull is also available as a single trailer-end or a single vehicle-end 4-way flat plug. Combine this Easy-Pull extension with either the vehicle-end plug or the trailer-end plug for the easiest possible disconnection. With ring handles on both connectors, disconnecting is as simple as gripping the rings and pulling straight apart. No wriggling, no broken terminals, and no damaged wires.

Just what I needed to extend the trailer wiring and now I have trailer lights. A former owner had cut the existing plug off to use on a different trailer, when I re-wired the plug end I needed a little more length to make a good fit.

Excellent product for the best price around. The grab rings make the process of hooking up trailer lights so much easier. 24" inch length was perfect to attach trailer lights to truck using a 32" extension hitch receiver. Shipping was fast. Glad I ordered.



- HM47004
by:

Product is exactly as I wanted and accurately described. The large finger rings make pulling the 4 flat extension much easier and with less risk of damage to the wiring harness connections. This extension is a tiny bit more expensive than a plain flat plug but it is worth the difference if, like me you have to pull the wiring harness connections after each use of the boat trailer. Buy this!

I havent used it yet this year, but I used the extension all last summer and it worked perfectly.

Excellent pull ring design for quick connection and disconnect. I purchased for the convenient 2 foot length. I’m happy with this 4-way wiring.

A good product at a fair price. The rings make it much easier to plug in and unplug the wires/harness. When it is difficult to plug in and unplug the wires there is a greater probability that something is going to get damaged. If you have had that problem you know what I mean.



- HM47004
by:

The extended terminals with the ring for a grip is especially helpful when using with a newer pickup plug. With the standard trailer wiring my thumb leaks blood every time I unhook. I purchesed this to cut down on my need for band aids.

Still working great... wouldnt trade for them.

I like how the product is so easy to disconnect. It is easy to store and works as expected. The one issue I have is connecting. The single pin part of the connector is difficult to get started for connecting my trailer wiring. This is similar to most connectors of this kind so I cannot be too suprised or disappointed.

These guys are great and all the parts I have ordered have worked perfect. Just installed a hitch and wiring kit and every thing was easy and works. I have not installed this trailer wire connecter but it looks heavy duty and well made and I am sure it will work fine. Thanks



- HM47004
by:

These are just brilliant. I don't know why it took so long to figure this one out. I permanently attached the existing trailer wires just long enough to attach this extension. If the cable gets wrecked, I only have to replace the extension, not rewire the trailer. That system has been working very well so far also.

Very useful product as the connection/ disconnection process of a trailer is frustrating at times when the connector is dirty or sandy. This particular unit is easy to install and use and makes attaching and de-attaching the wires very easy.

  • LED Lighting Kit and Mounting Brackets for Saris MTR 4 Bike Bike Rack
    I would be happy to help you set up your rear light kit item # 98174LED. I just called my rep at Saris to get the total length of your MTR Bike Rack for 4 Bikes item # SA4032-34. He said that bike rack is 56" long from the hitch to the back of the last extension. The LED Light Kit item # 98174LED has an overall length of 88" but the driver's side portion looks to be shorter as it comes out of the y at only 46".

  • Hitch Extender for Towing Small Trailer
    As long as you are staying within the manufacturers specification in regards to the weights you will be perfectly fine. The Curt Extender # C45796 has a tongue weight capacity of 350lbs and 3500lbs towing or 50% of hitch capacity, whichever is less. In your case for your 2014 Subaru Outback that would be 300lbs tongue weight and 2150lbs towing. You will also more than likely need a Wiring Extension # HM47004 as well as Safety Cable Extensions # RM-910648-20. Be sure to keep these secured...

  • Mounting 4-Way Extension on Factory Hitch of 2021 Toyota 4Runner
    Thanks so much for the photos, and there may be an option for your 2021 Toyota 4Runner which will allow you to mount the 48" Long 4-Pole Loop with Cover # HM47115. I can't quite tell if the section the hitch is attached to has an opening above it, but if so, you could mount brackets just to the left of the hitch with the No-Drill Mount # 18140 and Mounting Bracket 4-Pole Flat # 18144. If there is not an opening that allows you to attach the No-Drill Mount, the only option I can see...

  • Adding Fold Away Hinge To Front Of Trailer and Extending Tongue 12"
    If you add on the 12" extension to the front of the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 this will change your tongue weight slightly as well your maneuverability may be different as well. Otherwise there is no issue attaching the hinge in the manner you are wanting. Be sure to get a 4-Flat Extension # HM47004 for the lighting as your current wiring will likely not be long enough to reach the connector after you extend the coupler.

  • 4-Pole Wiring Extension for Connecting Reese RAM Lighted Hitch Cover RP86531 on 2015 Ram
    If you want to install the Reese RAM Lighted hitch cover # RP86531 and its 16-inch-long 4-pole wiring harness is not quite long enough to reach your truck wiring you can simply use an extension. We have 4-pole extensions in many lengths, such as the 12-inch # HM48148, 24-inch # HM47004 and 48-inch # HM47114. We also have a 10-foot extension # HM48235 but this one does not have the special Hopkins Easy-Pull connectors found on the other extensions listed.

These extensions will plug into the 4-way flat connector on your tow vehicle and the connector on your trailer and have an easy pull finger loop to make disconnecting the harness even easier. If this is not the extension you meant just let me know. I included videos for the products mentioned for you to...

  • Recommended 4-Way Flat Wiring Extension for Lighted Accessory
    For a 4-way trailer wiring extender, I recommend the Hopkins 4-Pole Loop - 12" Long # HM48145. If you need a slightly longer extender than that, I recommend the Hopkins Endurance Easy-Pull 4-Flat Extension w/ 2 Grip Rings - Vehicle and Trailer Ends - 24" # HM47004.

  • 4-Way Prong Wiring Needed That is 8' Long
    If you are looking for just an extension then the Hopkins 4-Pole Flat Wiring Extension # HM48235 that you referenced is 10' long and will be exactly what you are needing. For a flat towing application we have the common 4-Way round connectors like part # HM47046 which is 8' long or for a 4-Way flat connector you would need both the part # RM-300150-00 (6') and the part # HM47004 (2'). Let me know if you are looking for something different and I can make a recommendation for you.

  • Trailer Connector Extension to Make it Easier to Plug in Trailer to 2014 GMC Truck
    To make it easier to reach the 4-way connector on your 2014 GMC we have a 4-way trailer connector extension by Hopkins that's 1 foot long, # HM48144, or 2 feet long, # HM47004. Both of them plug into the existing 4-way and just extend it further out from under your truck's bumper. You can leave the extension plugged into the truck and use the included terminal grease to help protect it.
