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.

Product arrived on time, in perfect con dition. 694066

- HM47114

My review is basically on the DESIGN ONLY, because I haven't used it very much so I can't give a honest review on the actual quality, the DESIGN is awesome, the idea of making such where you can pull directly out is ingenious, some of us who are used to having to wiggle such to pull connections apart need to break that habit with this new design, I DO recommend using some type of electrical grease on the terminals when you attach. 660553

After a year of use I would highly recommend

This wiring set up makes trailer electrical hook ups much better of an experience. Everything attaches quickly and effortless. Before it was a pain especially after the wiring had a season on it. 660533

Makes connecting and disconnecting easy, no more knuckle busting 634388

Excellent design. So much easier to grasp the connections with the hole, plug in, and unplug. 416865

- HM47114

Bought to use as a back up after some stole my regular light cord (one of this company's coiled 4 flat to round plugs). Seems like a great product and if it is half as good as the other product I will be happy. It is small and easy to carry as a back up if something happens to whatever you normally use. When something happens to your lights like I had happen this is a great insurance policy. 403469

Wiring harness is awesome. Good quality, good price. Clever idea. First one was damaged during shipping and they had a new one at my door within a week..very happy. 384164

  • Recommendation for Extending 4-Way Connector at Rear of RV
    To help with unplugging the E-Z Mount Tow Light Kit # EZT20B 4-Way connector from your RV, I recommend looking at the Hopkins Endurance Easy-Pull 4-Flat Extension # HM47114. This will give you a 48 inch extension with large grip rings on both ends for even easier disconnecting. I have attached a short video demonstration on this product that you can also take a look at.

  • LED Light Kit and Swinging Arm Add-Ons for 22x59 Rola Cargo Carrier
    The 22x59 Rola Cargo Carrier for 2" Hitches # 59502 isn't compatible with the Rola Cargo Carrier Swinging Arm Assembly # 10421, but you can use a swing away adapter to gain that feature with this carrier. I recommend using the Kuat Pivot which is easy to use and comes in 2 different models; one that swings to the passenger's side # PVP20B and one that swings to the driver's side # PVD20B. Typically you want to use the one for the passenger's side because you won't be loading/unloading out...

  • Is There a Coiled 4-Way To 4-Way Extension Available?
    The Wesbar Trailer End Connector - 4-Flat - Coiled # 54000-026 will work to connect a 4-way plug like # HM48190 to the pigtail end to create exactly what you are seeking. Otherwise, we have options like the Hopkins Endurance Easy-Pull 4-Flat Extension w/ 2 Grip Rings - Vehicle and Trailer Ends - 48" # HM47114 to span that distance without the coiled wire.

  • Recommended 4-Way Connection Between Towed Vehicle and Motorhome
    The only real advantage of the 4 round over the 4 flat trailer connector is the clean look of the connection point and the protection from elements when not in use. For instance the Pollak Heavy-Duty, 4-Pole, Round Pin Socket, Concealed Terminals - Chrome - Vehicle End # PK11410 has a clean finished look on the front of a towed vehicle and will protect the connection from dirt and debris with the spring loaded cover. Many people like the connection between the motorhome using a harness...

  • 4-Way Extension to Get 4-Way Up to Front of Homemade Trailer
    That looks like a standard type of connector that vehicle manufacturers will use for various connections. I couldn't give you a part number for it though. Easiest option would probably be to cut that off and then use the 4-way extension part # HM47114 which is 4 feet long to get you a standard 4-way ran to front of vehicle.

  • 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.

  • Trailer Wiring Adapter for 2019 Ford F-250 to Provide Lighting for Headache Rack
    Usually headache racks that have taillight functions like what you mentioned use a standard 4-way trailer connector to power the lights so your best solution is the part # C55384 which plugs in line with the 7-way you have now and provides a 4-way and harness you can use for the headache rack and also leaves the 7-way totally functional. You'll want a 4-way extension too with part # HM47114.
