Video Transcript for Tekonsha Trailer Breakaway Kit TK2051 Review

Today we're going to be taking a look at the bolt on battery box for breakaway kits. The battery case is going to guard your breakaway battery and charger from the elements. This is designed for use with the Tekonsha trailer breakaway kits, but it will also fit many other batteries. To open it up you just pry this side open, it's got the plastic tether strap on this side so it keeps the lid attached. Taking a look on the inside, you can see down at the bottom that it does have some supports, that's designed to keep the battery off the base of the box, or off the floor of the box. It's also going to have holes in the base of the box to prevent moisture buildup, and then here on the backside, when the case is closed, you'll see that it has this small little slot right there so that's going to give you room to run the wires out of the box. It does feature a lockable design, it's got a tab right here with a small hole in it. That hole's going to measure a quarter of an inch so it will accept a padlock that has a quarter inch diameter shackle.

Padlock is going to be sold separately, but again it does have that lockable design to help deter theft. It's made from a heavy duty polymer construction to resist corrosion and for strength and durability. Here on the backside it's got the mounting tabs, that's these two tabs right here, each tab's going to have two holes so it's going to have a total of four holes, that way you can mount the case almost anywhere. Hardware is not included. The product is made in the USA. When it comes to the internal dimensions, that's going to measure five and fifteen sixteenths of an inch long by three and one eighth of an inch wide by five and a half inches tall.

The overall height of the box is going to measure six and one eighth of an inch. The overall width . I am including the mounting tabs in this measurement, so outer edge to outer edge it's going to give us an overall width measurement of about seven and three quarters of an inch. From front to back it's going to give us a depth measurement of right around four inches. Taking a look at the mounting holes, here on top these holes are going to be separated apart from one another on center by about seven and one eighth of an inch. Here at the bottom that measurement decreases just a little bit by about an eighth of an inch, so center on center, those are separated by about seven inches.

Going up and down, we're going to have a hole separation on center by right on three inches. That's going to do it for today's look at the bolt on battery box for breakaway kits.

Bought two different boxes as there was a slight difference in measurements. I could buy both, shipped to my door, for the cost of one locally, which they did not have in stock and I would have to wait a week to get anyway. Etrailer is the best! 353598

This is exactly what I needed for a 12 volt battery to go in my kayak for a fishfinder. I will have to grind off a little plastic on the inside to make it fit but next to nothing on the internet was out there but this nice little box that would fit the battery inside. 272534

  • Where do Switches Mount on Ultra-Fab Power Twin II Electric Stabilizer Jack
  • There is no specific secure box made to mount the Replacement Switches for Ultra-Fab Power Twin II Electric Stabilizer # 39-841643 for the Ultra-Fab Power Twin II Electric Stabilizer # UF39-941705. Any protected environment you have available would be optimal, and as you can see from the accompanying photos from our customers who have mounted these switches, there are varying locations. One solution would be to use something like battery box # TK2051 and drill into it for the wiring.

  • Battery Box for a 4-1/2 by 2-3/4 by 4-1/4 Inch Battery
  • Yes, your battery will fit in Curt battery box # C52022. The box is 6" x 3-1/4" x 5-1/2" on the outside and the inside is only slightly smaller. Another option is # TK2051. On the inside it measures 5-15/16" long x 3-1/8" wide x 5-1/2" tall.

  • Can Trailer Breakaway Battery Be Mounted on It's Side
  • If you are using a breakaway kit like the Hopkins Engager Trailer BreakAway Kit # 20099 that features a sealed battery in an enclosure then you can mount it sideways if that is a better mounting solution on your trailer. We do often see trailers with their breakaway battery installed in this way. If your kit does not use a sealed battery or if it does not have a protective case for the battery you might want to check the manufacturer's instructions for any cautions about how that particular...

  • Can a Breakaway Battery Be Used to Power an Interior Light
  • Yes, you can use a breakaway battery to power the interior light on your enclosed trailer. However, these batteries typically only have a 5 amp hour rating so that is something to make note of. If you were to use an LED interior light like the Optronics LED RV Interior Light with Switch part # RVILL34 then you would not have any issues as it only draws .6 amps of power. With that being said, you will not need the Tekonsha Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger...

  • Protecting a Trailer 7-Way Connector While Trailer is in Storage
  • Covers for 7-Way trailer connectors are very uncommon and the only ones we have are attached to powered jacks. An inexpensive solution would be to use a small battery box such as # TK2051 and slightly modify it so you can put the 7-Way in it. I also recommend adding some dielectric grease, # LT37534, to repel moisture.

  • Battery Recommendation for the Battery Box # TK2051
  • The Replacement Battery Box part # TK2051 that you referenced has internal dimensions of 5-15/16" long x 3-1/8" wide x 5-1/2" tall and is designed for breakaway batteries like the # HM20008 that would easily fit in the box. This battery measures -1/2" L x 2-3/4" W x 4" H.

  • What are the Dimensions of the Converter Box in Vehicle to Vehicle Tail Light Converter 118158
  • We have a converter # 118158 laying around so I measured it. The box measures 2-15/16 inches by 2-7/16 inches by 1 inch. You could use a small battery box such as # TK2051 to better protect the converter from the elements. The converter will generate some heat so the box you put it in will need to be larger than the converter and it will have to have some ventilation. The battery box is the perfect combination of size and ventilation.

  • Replacement Battery Box Recommendation to Replace one on 1994 Model 9419 Featherlite Horse Trailer
  • The battery that fits in box # TN65117 measures 3.54 inches long, 2.76 inches wide, and 3.93 inches tall. Including the terminals it is 4.17 inches tall. This would be a bit too small for you based on the dimensions you listed. Instead take a look at the Tekonsha Battery Box part # TK2051. This box has inside dimensions: 5-15/16" long x 3-1/8" wide x 5-1/2" tall which would fit your battery well. The mounting holes would be different but you could still mount the box on your trailer.

  • Will Replacement Sealed Lead Acid Battery for Shur-Set III Breakaway Kit Fit Battery Box TK2051
  • Yes, the battery and box will work together. Replacement breakaway battery # TK2023 measures 3-1/2 inches long, 2-3/4 inches wide, and 4 inches tall. The battery box # TK2051 has internal measurements of 5-15/16 inches long, 3-1/8 inches wide, and 5-1/2 inches tall. I have linked video reviews of both products for you.

  • Needing a 2-3 Wire System that will Seperate the Turn Signals from Stop Signal
  • I do have a part that will work for what you are needing, but the Hopkins Tail Light Converter Kit, part # HM48895, will not take a 2 wire signals and split it into a 3 wire signal. To split your 2 signals into 3 you will want to use the Tow Ready Vehicle to Vehicle Tail Light Converter, part # 118158. This will take your combined turn and stop wires and separate them into right turn, stop, and left turn wires. Please note that this converter does not work well with LED lights. Another...
