Pollak 10-Terminal Junction Box

Great box for making all the connections for the plug harness, trailer brakes, and the brake battery and safety switch. etrailer has all the parts needed to rewire a trailer from plug to lights!!! 678306

Excellent, I have organized my trailer wiring for lights,brakes, aux lights, and area lights.

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 700033

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. 317861

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. 413583

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. 184871

Ok junction box, does the job its intended for. Gave it four stars because it "feels" cheap. But it works great. I was just careful not to over torque the nuts on the studs because it "feels like" they will pull out if you over tighten the nuts. So be careful. 960574

Only reason ill give this product 4 stars instead of 5 is, just wish the case was a little bigger for the 20 wires. But what do you expect when you try to shove 20 wires in a box? ;) Product works great! 820822

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. 793723

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. 168161

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

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. 446928

I haven't put it on the trailer yet, waiting on one part that I order. But, looking at it... it well built and like how it has pretty room to bring in many wires and keep them looking like a professional install them. 695976

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. 180875

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. 493023

So far so good, everything works great.

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. 581076

Good afternoon I found your products to be very good quality and I look forward to putting them through the paces considering I work at a training center. Your service reps were very product knowledgeable and answered all of questions and didn't push me toward something I don't want or need. I look forward to working with you guys again in the near future. 573281
