Video Transcript for Polar Hardware Enclosed Trailer Parts - Doors - 305736 Review

Today we'll be reviewing part number 305736. This the Red Line 36 inch Lock Side Door Bar Lock Assembly. We'll measure the overall length, you'll see that it is going to give us that 36 inch measurement. This system can be used on either the left or right hand side of the door. All you'd need to do is flip it around, and then you can still mount everything the same. No hardware is included, so keep that in mind, that you will need to purchase mounting hardware in order to get this set up correctly. Everything that you see here is included--you're going to get the bar, the hinges are already on there, the handles are already on, and then you get everything that you need to mount to the door, to lock the handle in place.

The only thing that you may need to purchase separately is an actual lock that goes through these holes here. That way you can secure it and make sure that nobody can get inside the trailer or open up the door without the key for the lock. Let's go over a few measurements real quick. Between our two mounting holes on this side--it's going to give us a measurement of four inches. Then down here at the base--we're just going to go over the diameter of the hole, this is a square hole, so it's going to measure the same on each side, it's going to be 3/8 of an inch. And then the distance between these two mounting holes, center to center, is going to give us a measurement of 3 1/4 of an inch, and the diameter of the holes on the hinges are also going to measure 3/8 of an inch.

That's going to be identical for both the bottom and the top, or the top and bottom. The distance that we have from the outermost holes, so bottom and top of the hinge, center to center, is going to give us a measurement of 34 and 3/4 of an inch, and then the inside holes, center to center, is going to give us a measurement of 28 1/4 of an inch. The ideal length from the bar to the center of the mount for the handle is going to need to be right around 6 inches. And then the width of that mount itself is going to measure right at 2 inches. So again, it's very easy to install. You just need to make sure you that you have nice, secure screw or bolt applications that you can mount directly into the trailer, or whatever you're mounting this to. You want to make sure you have a nice sturdy connection. Maybe directly into the frame, or a nice support.

So you have two holes here on the hinge, two holes here at the hinge, and then you'll need to mount at this point here. This does mount on to a raised portion, or raised lip, so that way once you have it mounted, you'll be able to swivel that, and drop it, and then you can raise or lower the handle out of it's location, and open up the door, and then you can swing it back in place to lock everything up tight. The diameter of this bar is going to give us a measurement of right at 1 inch. And that's going to do it for today's review of part number 305736. This is the Red Line 36 inch Lock Side Door Bar Lock Assembly. .

Prompt shipment, Quality product, insufficient dimensional detail to determine the designed relationship between the hinge mounting surface plane and the door surface plane when door is in the closed position. Had to buy the product in order to determine the applicability. Was able to adapt after determining the required shim thickness.see attached pix. 563807

Product shipped quickly! Was at my door 3 days later. Took 45 mins to install by my self very easy! It helped reading reviews to insure it was installed right. I would definitely recommend a brace inside of door where latch is door was flimsy. 269445

Thanks for the follow up. We just bought a Look 6' x 12' cargo trailer that only had the in-door lock on the side door. Of course we wanted to beef that up and in searching found your site. After reading the reviews we ordered the #305736 36" side door bar lock assembly on 1/20 and received it 1/22. Great! We installed it the next day in about an hour. It went on with minimal effort (drilling the holes was the worst) and looks as if it came on the trailer. We did install the hinge side over the door trim and used backer plywood inside with oversized washers and locking washers. We did the same for the door bracket. The pictures on your site from customers helped us, so we have attached a couple of our own. Thanks e-trailer! The Wheelers 115131

Did not think I would have to shim hinges out 1/2 in. Would have been nice if you supplied Shims. If not for that problem, I would have been very happy. 380638

I paid for installation, due to the fact I have a brand new trailer and didn't want to mess it up! Without question this bar lock does the job. I have a Wells Cargo trailer, and this same part would cost at least $100 more if I ordered it thru them. The latch was a bit too large (both wide and tall) for the "hockey puck" style Master lock I purchased to secure it, but a metal file and about 10 minutes was all it needed. Just a small trimming of metal was all it required. The 2 rear door bar locks (factory installed) needed similar attention. Sorry I have no pictures. I store my trailer a few miles away so it's not handy. But my installation looks just like everyone elses. 183521

The Lock Side-Door Bar is what should be on the door. I security it gives me now hauling the trailer down the road is comforting knowing that it will no long swing open in its original state with just a key entry lock. My husband was happy with the simple install and it matches what I already have on the drop back door. Very happy with the product. Highly recommend it. 358930

I just received the 36" Bar Lock Assembly. Thank you for the quick shipment, I received it in 5 days, much faster then any other parts I have ordered from other places. I am going to install the product this weekend and will let you know how it goes. Thanks for the great service 34898

The products are exactly what I needed, I got an estimate from a local company to do the lock change and install the bar on my trailer door for $325.00 when I remembered I had purchased from Etrailer before so I got on-line and within days received my parts from Etrailer for $xx.xx and will install myself. The only dissapoitment is there is no hardware to install the trailer lock bar so now I have to deal with that and locate where to get the proper hardware. I just assumened it would come with it so I think this information needs to be known to the customer before they order, I have looked on the site and I can not see anywhere that Etrailer even sells the hardware for me to order from them. I feel like I bought a pair of new shoes with no shoe laces, however the shoes are very nice! 310720

I just attached the 36" latch bar. it only took about 30 minutes. Took longer to make sure it was positioned right and not to impede on the rv latch. I included a small bracket on the door as well. Latch hardware seems better the originals on back. 5/16" carriage bolts are needed. I used 2 1/2" then cut off anything past the nut. Pictures included. 104942

Michael,Im doing exactly what you did putting this bar lock over an RV style door. The door is about 12 from being flush with the trailer side and it looks like yours may be too. Did you bend the strap to get it to lay flat against the door? I thought of spacing out the hinge plates so theyre flush with the door but dont think that would look good.Also, did you remove the rear lip on the aluminum trim the hinge plates are mounted over, space under the hinge plates, or just mount over it?Thanks,Steve

Steve,there is an aluminum trim around the rv door, I just bumped the hinge of the bar to the closest lip of that alum. trim to the door basically mounting over the top of the trim -so on top of the left side bump and bumped the right side if that makes sense. it kinda naturally fits. the bar lays nice and tight to the door by just mounting it ad is. Add some metal straps on iside of door mount to beef that up. I used 2 or 2.5 inch bolts with oversized washers on inside alum. jamb and cut off excess bolt and grindedsanded smooth to nut. I siliconed the gaps on the outside above hinge because it wont sit flat due to the alum. trim so water doeant get on by bolts. Hope that helps.

Is there a weak point created when bolting the hinges so close to the edge of the door opening? Could you install one of these by moving the whole assembly to the left, thus creating room for hinge backplates? I guess you would have to lower the mount point as well, to avoid the doors backplate from hitting the factory lock and use a shorter but wider door backplate.I assume you feel your hinges are secure. I have yet to take ownership of my trailer so I dont know what kind of stud is framing the door.I am so happy this accessory is available. I really didnt notice the pitiful side door lock until after I purchased my trailer. A crowbar and about 5 seconds is all it would take to get inside!

Usually these latches are not positioned so closely to the edge of the door. Most of the time, the hinges of the handle side and the latch for the handle are set equidistant from the edges of their respective doors.

Still in the process of getting this mounted, but it seems like a solid piece of equipment. One thing to note: this is made for applications where the door is flush with the trailer frame. My trailer door rests on the frame when shut, so it sticks out about a half inch. To compensate, I had to buy some aluminum bar stock to cut and mount under the hinges. Also, I apparently need to find a carriage bolt with a bigger head for the little swivel piece, as the first bolts I picked up had too small of a head to secure that piece in place. 256915

Pretty nice product. Appears to be made in the USA by Polar. One of the welds is what I would call sub par, but the rest look OK. Easy install on my cargo trailer's side door. Takes 5/16" carriage bolts. 140443

Received the item very quickly for having chosen the "economy" shipping. Installed on 2015 Haulmark Transport side door for additional security, used in conjunction with a puck lock. Install was easy with the help of the reviews from this site, particularly the one from Michael K. I attached mine in the same manner as Michael, on top of the aluminum trim and butted up against the lip. I believe it would be just as functional and still secure through a vertical post if secured at the edge of the aluminum trim, however there seems to be better door engagement with it on top of the trim. I've attached a close-up of the mounting, as the description in other reviews is lacking in clarity. The door is rather flimsy on the this model of trailer, as I'm sure is the same with most trailers, so some backing will be required inside the door for the mounting hardware to distribute the load. I used a 1/8"x2" strap steel that I found at the local hardware store. Very satisfied with the end result, quality product at a great price. 159165

Holds door securely shut. I added a custom bracket to stabilize the side of this homemade box, by using the back door as a shear wall. See special bracket just below top hinge, under rod. The right wall cannot vibrate when driving, or be pushed out by contents inside. 212627

We recieved our door-bar on Thursday Evening, and Friday I installed it in about an hour. I purchased $7.50 worth of carriage bolts & washers & ny-lock nut. 2.5 carriage bolt for the 36" rod hinge & 2" for the door. Our older Aluma trailer door lock with the "rod & lever" closure was not keeping the door completely closed plus the keys are obsolete and needed a new key. With this set up my doors stay sealed to keep out dirt & dust and I can use any heavy duty lock. (Lock upgrade purchase soon) Thanks for fast delivery service too. Odered on Monday & recieved on Thursday! Plus we love our 1.25 receiver hitch for our VW Jettawagen which we use to haul our bicycles! (purchased in October). We Paid $75 to have it professionally installed but saved $100 on the hitch. 162136

It’s going to make my trailer more secure than the little door lock. It should include some mounting spacers, as there is a lip around the door. I fabricated my own so the bar would clear this lip. 727330
