Battery Side Bolt Extender - Brass - Short - DW05416

Average Customer Rating:  4.6 out of 5 stars   (42 Customer Reviews)


I built my recovery trailer built, than ks


The lug terminal for the 10ga wire would not fit the item, It also had a steel nut that will rust in less than a year on the battery. I did not use it and will not bother returning it as it will cost me to return it. I got a gold plated one that the 10ga lug fit and from auto zone, It cost about the same as yours.

Also I ordered two and only received one in the mail, I guess I will be charged twice for postage.

Thanks for the follow up Mike. I have requested that customer service contact you regarding the shipping issue.


Awesome selection, great prices, knowledgeable sales people and quality products. After viewing the many different options and narrowing down to a few selections I liked, my AWESOME sales person Kat really helped me decide on the proper trailer braking module and towing hitch I needed for my situation. I simply wanted the best highest quality product on the market for my set-up period, That's what I got without compromise! EVERY part of this process was very easy and couldn't be happier! is "good as it gets" in my book. I'm a tuff critic when it comes to quality parts and knowledgeable service and EXCEEDED my expectations! I recommend everyone I hear inquiring or talking about trailers to My son purchased a new trailer just after I received my parts from and was so impressed with my experience he called and received the same professional knowledgeable service and parts as I did. I know with confidence I have the BEST trailer components on the market when I'm pulling my double axle enclosed motorcycle trailer to the races.
Thank you Kat and !


This fit my battery perfectly and was easy to install. The only problem I had was this was recommended with the Universal Installation Kit for Trailer Brake Controller and the post is to big for the supplied ring terminal. If you buy this with that kit you're going to have to buy some additional larger ring terminals.


Purchased the items listed after watching the video. Everything fit and worked perfect. The video was extremely helpful. Have bought other items from E-trailer for other vehicles and as with this order items were delivered timely.

Highly recommend E-trailer. Saves a lot of time running around trying to find everything needed for a hitch and brake controller install.


Does the job for GM trucks with dual batteries and a big cable running between them. I wanted to add a battery maintainer that came with ring crimp connectors. This did the job. The ring connectors never fit properly UNDER the cables and I was worried that that arrangement was preventing a good connections of the cable to the battery.


I purchased everything required to wire a 7 pin trailer connector for a 2011 Chevy Express van.

The best thing I can say is the video series specific to the vehicle was amazing.

Quality of the parts was very good.

All of the parts arrived in good codition, with fast shipping to Vancouver Island, Canada.

Would definitely order more from this company.

Well done.


Works as described.


These side battery terminals have performed very well. They are great for connecting the accessories to the battery.


Nice product.Required for Winch power connection. Good for any additional power or ground wire connections when using side terminal batteries.


This item was easy to install and use. My main complaint here was the use of a cad plated steel nut. Long term, I will want to replace the steel nut with an appropriate brass nut (3/8-24) if I can find it. Second choice would be a stainless steel nut. The cad steel nut will be likely to corrode relatively quickly.


the batt post extenors will work great in my dodge ram for the extra running lites-elec fan and future items i will install on my pickup great price from etrailer and great shipping


These are a must to connect 2 wires to a side mount battery. They will also help if you need to jump off your truck. GM should have made these part of the original battery.


This is a handy way of making an electrical connection to your battery!


Product worked great as described. I used it in my 2003 Grand Prix since I needed a place to hook my Amp power wire.


It fit the battery and cable well. The Van is now starting fine.


Delivered on time. Exactly what I was expecting. Good quality. Holding up very well. If I ever need another one, will not hesitate to order again.


This product is amazing after owing it for a year haven’t had and troubles, easy to install definitely recommend it


Product good quality. Took longer to recieve than expected using basic mail option. Would have been cheaper and quicker to get item from local [retailer].




eactly what i needed at a good price , delivered quickly. what more could you ask for?


Everything came together and went in sm oothly!


Excellent little piece! Easy to work with and makes install a breeze.


Got to have this to connect all the new wires to the side post battery.


Great service and product

  • How Would Winch Circuit Breaker Attach to Side Post Battery
    With side post batteries you can use extender adapters like the # DW05416 to allow you to easily connect accessories to a battery like the winch circuit breaker you referenced.

  • Recommended Battery Terminal Extender For 2014 Chevrolet Suburban
    Typically, when you need to install a 12-volt power wire, such as a brake controller installation, it is to the positive battery terminal. Often we find that there is just not enough post to attach the new connectors to so we recommend a terminal bolt extender like part # DW05417. If a shorter extender is needed then you can use part # DW05416.

  • What Amp Breaker Should be Used to Install Brake Controller Towing Trailer with 4 Brake Assemblies
    The diameter of the stud on the Battery Side Bolt Extender # DW05416 that you mentioned is 3/8 of an inch. For a ring terminal designed to fit that you would want the part # DW05705-1. I would also recommend you go with a 20 amp breaker like part # 9506P if you plan to tow a trailer with up to 4 brake assemblies. Otherwise the warranty of the controller would be voided.

  • Recommended Trickle Charger And Towing Mirrors For a 2021 Chevrolet Express Van
    You will not need a Battery Side Bolt Extender # DW05416 for your negative battery terminal on your 2021 Chevrolet Express Van. Instead you will be able to connect your negative terminal for a Trickle Charger # MA22WR to the nearest body ground point. I recommend using the Longview Custom Towing Mirrors # LVT-1700. These are custom fit to attach over your current mirrors. They fit snuggly so you will not have a much vibration in the mirrors as with universal mirrors.

  • Recommended Brake Controller And Wiring For 2000 Toyota Tundra With No Tow Package
    Since you have no trailer wiring on your 2000 Tundra, you will want to first install a 4-way like part # 118367. You can plug this into the wiring that is on the driver side frame rail near the back of the Tundra. I have attached a photo that shows where you can find this plug. You will then find the connector located between the battery and the fender under the hood. I have attached a photo of this as well you can check out. The brake controller I recommend is the Tekonsha Prodigy...

  • Parts Needed to Add 7 Way and Brake Controller to 1998 Chevrolet Truck
    To add a brake controller to your truck and swap out the connector with a 7 way you'll need a few parts. You'll need a working 4 pole flat trailer connector (which you said is currently on the truck), the Universal Installation Kit for Trailer Brake Controller # ETBC7 and a brake controller. The ETBC7 kit comes with all the connectors, breakers, and wires to get a brake controller installed and a 7 way at the back of your truck. The 4 pole wiring will plug into the ETBC7 and then wires...

  • Brake Controller And Wiring Recommendation For 2012 Dodge Grand Caravan
    Without Factory Trailer Connector means the vehicle has no 7-way connector at the rear for hookng up a trailer. You may have a 4-way trailer connector on your 2012 Dodge Grand Caravan. If you have a 4-way connector on the backof your Grand Caravan, then you would need the Universal Installation Kit for Trailer Brake Controller, part # ETBC7. This will give you both a 4-way and a 7-way connector at the back of your vehicle. There is some additional wiring that has to be done. I have attached...

  • Recommended Wiring And Brake Controller For 2005 Subaru Impreza Sport Wagon
    The number you referenced is actually the part number for the converter on the wiring harness from Draw-Tite. I called my contact at Draw-Tite and they told me the symptoms your system has are the converter. Since it is not sold as a separate item, the harness will need to be replaced. The Draw-Tite trailer harness with a powered converter is part # 119147KIT. We have had several customers send positive reviews with this harness. Since you are planning on getting a trailer with brakes...

  • Trailer Hitch And Wiring For 2012 Kia Sorento SX Towing A Pop Up Camper
    Since you said you do not have the factory installed wiring on your 2012 Kia Sorento SX, I assume you do not have the tow prep package. If that is the case, I recommend the Draw-Tite Class lll Trailer Hitch, part # 75684. This has a 2 inch receiver. This hitch will not fit models that have dual exhaust with a tailpipe on both the driver and the passenger side. I have attached a link to an installation video for this hitch on a 2012 Sorento you may want to take a look at. You said you are...

  • Curt Brake Controller Installation on 1998 Chevrolet C/K Series Pickup with Long Bed
    To help installation of the Curt TriFlex Trailer Brake Controller # C51140 go smoothly, you will want a 4-way connector, the universal wiring adapter for Curt brake controllers # C51515, and the universal installation kit # ETBC7. If you do not already have a 4-way connector on your pickup, you will want to begin by installing one. I recommend the Tow Ready T-One Vehicle Wiring Harness # 118315. This wiring harness plugs directly in your vehicle's pre-existing wiring with no cutting or...
