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. .

This junction box provides a quick and easy way for you to connect the trailer plug to the trailer wiring. The box also makes your trailer connector simple to replace.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
This is the third one of these I have bought. I have nothing but good to say, room to grow excellent. 442867
Ken - 10/15/2018Very 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
Nice product as advertised, I still like etrailer 545650
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
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
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
ARIC - 11/22/2017worked well. 733293
Good price on a quality, hard to find product. Shipped quickly and well packaged. 715765
Wonderful product for an even better pr ice. 706417
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
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

As described. Fast shipment. Great site 604067
very handy when wiring up a large trailer with many lights. 583881
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
