Video Transcript for Ultimate Overview of the Pollak 10-Terminal Junction Box

Today we're going to be taking a look at part #PK52248. This is the Pollak 10-Terminal Junction Box. This junction box is going to provide a quick and easy way for you to connect the trailer plug to your trailer wiring. The box is also going to make it very simple and easy for your trailer connector to be easily replaced. It's going to feature a nice black durable ABS plastic construction. Here on the inside, it's going to contain 10 terminals. These are going to be size 10 or .190 of an inch terminals.

It's got a nice little lid that goes over the top for a secure connection. It's going to come with the four bolts that goes in the four holes right here to connect the lid to the actual box. Let's go ahead and go over some measurements real quick. Now, the length of the box, not including the mounting tabs, is going to give us a measurement of 7 1/2 inches. The width of the box is going to give us a measurement of 3 3/4 of an inch. Then the height of the box is going to give us a measurement of 2 1/2 inches tall.

The mounting holes on this box are going to be separated center-on-center going this direction by 8 1/8 of an inch. Going this direction, those mounting holes are going to be separated, it looks to be, by 3 3/16 of an inch. You can see everything that it comes with here on the table. It's going to come with the nuts that are going to attach our ring terminals to each of the terminals located here in the junction box. That's what these 10 are over here. It's going to come with the four bolts to attach the lid to the actual box.

It's going to come with these four nuts, as well. Those are going to be designed to go on the backside of a bolt when installing this to your mounting location. Those bolts are going to be sold separately. You may already have those, and you may just want to use your existing bolts if you're just replacing the box. If you don't have some, you can, simply, pick some up at a hardware store, and you can use the included nuts right here. It's going to come with these grommets.

Four of the grommets are going to have the open design. Those are going to be what slides into this portion right here. You're going to have two slots on this side, two slots on this side, and two slots in the front. It's going to allow plenty of room for your wires to go through into the junction box, but it's also going to help in assisting keeping out any dirt or grime from getting in here and causing any type of damage or corrosion to the connection points themselves. You're also going to get two grommets that are solid. Now, these are going to allow you to cover up the slots that you don't want to use. That way nothing gets in there. If you want a tighter connection, if these holes are too big for your wiring, you can just make a little slit in there and use it for that function, as well. It's a really nice design. Again, durable ABS construction. It's going to come with a lock nut for each terminal, grommets, open and closed, to protect the connection points by keeping out dirt and grime. It's going to come with the bolts to get the lid attached. That's going to do it for our review of part #PK52248. This is the Pollak 10-Terminal Junction Box. .

Good product for what it does. Wish it was a little thicker. Makes a clean wiring job possible. Mounted mine inside a tool box along with the brake emergency battery. Did away with the "boat trailer" wiring the manufacturer had installed.

Still doing good. Helps that it’s out of the weather and sun.

Had to replace the cable connecting my Springdale travel trailer to the tow vehicle. I ordered the etrailer 50-67-005 cable and the PK52248 junction box. The original cable was terminated in a standard electrical box with all of the connections done with wire nuts. When I opened the electrical box and pulled the wires out to have a look-see, one of the white ground wires came out of the wire nut. This is not the first time I have had a "loose wire nut" problem with this travel trailed so I decided the new cable would be differently. The j box was mounted to a 2 X 6 steel tube so I used 1/4 inch self drilling screws to mount it. I also used 1/4 in. self drilling screws to mount the metal cable clamps to hold the cables, going into the box. I used a couple of pieces of 3m mounting tape on the back of the j box to hold it in place to the frame while installing the mounting screws. I also made a small label to go in the lid of the j box to show wire colors and function. There was going to be five ground wires connected so I made a small bridge out of 1/2 in X .062 brass to go on the two end posts. I think this made a cleaner installation. When everything was wired and checked out I sealed the open grommets with RTV. The intermittent problems with the cable are now fixed.



by:

Over the years I have installed 10 or more of the ten pin connection boxes on other people’s trailers. This time it was on my 5th wheel. It is a great box and makes for a much nicer fix in the future. I also had to replace the 7 wire pig tail because the plug was pulled off. I bought the 6ft. Coiled cable. I used a 1/2 inch clamp to hold the cable at the box and a Connect-to-Protect to keep the cable up out of the weather. The products are great and look great too. Thank you, Philip



by:

Very good product that made wiring my home made utility trailer easy. The box has plenty of room for your wires and long studs for those connections that need many wires, like the ground. There was also enough room above the studs for me to mount the Tow Ready 118158 converter to the cover and keep it protected. The 3 extra studs worked out perfectly to hook up the converter as well. Only thing that would make this better is if it included more solid grommets so you could make smaller holes in some or plug more of the openings, but some silicone sealant will fix this. I did most the wiring before mounting to the trailer, only had to connect the blue brake wires after mounting.



by:

I bought one to install on newly refurbished trailer that need a 10 post junction box. Installed fine but when attempting to changing wiring 3 of the post stripped out. Ended up cutting wires to remove. Contacted company and told no returns or exchange. I ordered another from a different company with no issues. No longer a customer of this company.

The EOH braking system works perfectly. You are my supplier of choice ifwhen I need additional trailer parts on the future.

Using the Junction box cleared up the rat's nest that was provided by the rv manufacturer



by:

I liked this terminal box for managing wiring on the back end of my truck. The previous owner did a hack job on the wiring when they installed an aftermarket bumper and headache rack so I used this to correct the problems they introduced. I repaired the wiring harness and then used an inline 7 pole 5th wheel splitter to run all 7 connections to the junction box rather than have taps in each of the factory wires. This let me take off multiple lights from the junction box with clean and easily maintainable ring connectors on the ends. I was able to safely wire the aftermarket blinkers and backup lights through the junction box rather than taps to maintain the integrity of the factory wiring harness.



by:

Nice terminal box. Cleaned up the wiring on a brand new cargo trailer that I bought where they had all the wires in a small box and wire noted together. Ground wire for the trailer brakes was not making contact. Connected everything in the new box with ring terminals and added a battery inside the trailer. Clean and neat, the way it should have come from the factory.



by:

I used this when replacing my seven round trailer connector. The ten terminals are a good idea. My trailer has a power winch, electric brakes with breakaway switch, 12volt power for inside the trailer, back up lights, and of course the required lights. Having all the available terminals made for easy wiring and clarity in wire runs. Much better than having a mess of wires in the battery box. This should be standard on all trailers.



by:

Still working great!!!!!!!!!!!!!!!!

This junction box will work great to clean up the wire routing I have on my trailer and make it easier in the future to trouble shoot problems.

So far so good, everything works great.



by:

Very happy with these junction boxes, mount securely. Added dielectric grease to cover and around inserts to make sure water stays out. I don't expect to have any issues down the road.



by:

Used this junction box to rebuild the wiring system on a new trailer. Have used this type before and was impressed with the quality and ease of use. Made the new wiring much more secure and protected.

One year later and it's working well.



by:

This was exactly the item I needed to make connections between trailer wiring, brake system and connector cable. Simplified maintenance and easy modification were my goals. Succeeded!



by:

Worked very well!



by:

Works great, mounted on the inside of the frame, had plenty of room for my wires and makes installing the new lights and IV cable a breeze.



by:

used this box to replace the old cracked one on my trailer and it does great.
My only problem is that the grommets provided are drilled out already, well two are solid ,but I have two holes now that need to be plugged to keep the weather out.....my suggestion is for pollack to include a few more solid grommets in the packaging.........other than that the terminals are solidly made and the box and hardware are all well made



by:

I saw this on the website and bought it as to me it makes wiring the trailer easier and makes it easier to test for problems when they occur. My ATV trailer wiring has to be replaced due to much salt from the road. This made the project a snap and the box is well made. Fast shipping too.



by:

I bought this box because It had 10 terminals,and extra space is a plus for future add on's. I also bought this one because it was more expensive and figured it would be better quality than the cheaper unit, but I feel that the plastic housing is flimsy and could break easily also there is no gasket on the cover to keep water out. It will get the job done but I not thrilled with it.



by:

I got this to replace a metal box that's actually supposed to be used in a house. The old box was corroded and rusty, and I wanted a better way to make connections and something that would be cleaner to work with. Clean was wishful thinking. While I appreciate that the box was taped shut to keep the extra parts in, the tape used was the worst stuff I've ever dealt with. There were many small pieces of tape that didn't come off, plus the adhesive left behind was a total mess. If not cleaned, it would have become a complete dirt ball in a matter of days on dusty roads. I soaked it for more than 2 hours with Goo Gone and still had to scrub and scrape. I got most of it, but there's still some that will be collecting dust. If Pollak would spend a penny or two more per unit on better tape, it would save their customers that aggravation. The other small issue is what's been mentioned before, not enough solid grommets. Like others, I'll also be stuck with having to close the extra space in some of the grommets with silicone. I just wish manufacturers would read feedback and make improvements.

  • Converting From Surge Brakes to Electric Brakes on 2012 K-Z Spree Travel Trailer
    We can start with the over-under conversion kit since that is pretty simple. Since you have a 2-3/8" axle you will need the Dexter # K71-384-00. This will allow you to mount the leaf springs on top of the axle on your 2012 K-Z Spree. Moving on to the brakes, I'm assuming with your 2-3/8" axle that you have 3,500 lb axles. Make sure to verify this information. Assuming that is the case, you will need the following: -Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand...

  • Mounting Hole Dimensions For Pollak 10-Terminal Junction Box # PK52248
    The Pollak 10-Terminal Junction Box # PK52248 has mounting holes that are spaced 8-1/16" on center across the box and 3-1/4" on center vertically. The holes are 1/4" in diameter for your mounting hardware. The Bargman 7-Way, RV-Style Connector w/ 12' Long Coiled Cable # WG54006-046 is a great cable to wire into this junction box. The coiled design help to prevent the cord from dragging on the ground.

    To re-wire your 18-ft trailer you will need a few things. I recommend installing a junction box like part # PK52248. You can run your trailer connector like part # H20044 to the junction box and use the terminals in the box to run the wiring to the trailer. For 7-way jacketed wire I recommend part # DW04914-1. This is sold by the foot. The junction box will also make it easier to install and use a breakaway kit like part # HM20001. This kit includes a charger and a weather-resistant...

  • Comparing Regular, Fused, and Circuit Breaker Junction Boxes for Trailer Wiring
    Given that trailer wiring only consists of basic light functions, 12 volt power, and brake output a system of fuses is not necessary because it is easy to determine if something is not working. If there was a short, the way you would know with or without a fuse junction box is going to be the same either way. You still have to fix the short and in the case of a fused junction box replace the fuse. A fused junction box would prevent a short from going any further than the junction box....

  • 2-Wire to 3-Wire Converter for RV with Combined Lighting and Trailer with Separate Lighting
    I have a solution for you, but there is not a plug-in adapter to convert your RV's taillights from combined wiring to separate wiring. If you are pulling a trailer with separate lighting, you will want to use a 2-wire to 3-wire converter. I recommend the Tow Ready Vehicle to Vehicle Tail Light Converter # 118158. This system will install below the 7-way trailer connector # H20046 on the trailer. The converter will keep the trailer lights as a 3-wire, separate light system while they work...

  • Junction Box Replacement Recommendation for Trailer that Uses Cap Connectors for Trailer Wiring

  • 7 Pin or 10 Pin Junction Box Recommendation for Wiring Up a Trailer
    The biggest difference between the two junction boxes that you referenced is the number of terminals. The # 38656 has 7 and the # PK52248 has 10. For a 7-way I would recommend you go with the 7 pin box part # 38656 since there would be no need for more circuits than you have. We don't carry the yellow marker (known as paint markers, available at local hardware stores), that you see in the attached video, but any marker or even a pencil could be used as long as it is visible to you.

  • Replacement 4-Way for Karavan Boat Trailer with 8 Wires
    Hi Ross; you have some extra running light and ground wires on there right now which isn't uncommon. You can still use the Wesbar Wishbone Wiring Harness # 002402 you were looking at, you will simply need to tie the ground wires and the extra running light wire together when you connect it. You can go the junction box route as well using # PK52248 which may make it easier to organize everything.

  • Recommended Junction Box For Individual Trailer Brake Wiring
    My recommendation for the junction box is the Pollak 10 terminal Junction Box, # PK52248. This will give you individual terminals for your 8 contacts. I'd suggest using the other two for a hot supply line and a ground line so you can just add jumper wires within the junction box itself. Your application will be a customized one, but this additional junction box will allow you to have the simple troubleshooting you desire. I would not go smaller than 12 gauge wire for trailer brakes,...

    To charge the marine battery in your trailer you need to run some wiring from the pin in the 11 o'clock position on your trailer 7-Way to your marine battery (see attached photo). This should be the same wire that your breakaway kit is connected to.

Otherwise the 7 terminal box like part # 38656 would be all that you would need.

Since you are just doing lights, you can just leave the rest of the posts unused without any issues. You will need ring terminals part # 44-5310A to connect your wiring to the terminals.
