Video Transcript for Polar Hardware Lock Side-Door Bar Lock Assembly Review and Installation

Jake: Hey guys. Jake here with etrailer. Today we're going to be taking a look at a replacement latch for your enclosed trailer. It is going to be available in 55 inch length like we do here and a 36 inch length. Just see etrailer. The kit is going to include your replacement latch and the new hasp so that you don't have an old hasp with your new latch.

The construction is going to be a fairly thick steel construction with a zinc-plated finish so that it holds up with the elements. The handle here on the end is going to be a rubber dipped handle so that it's going to give you more than enough grip to be able to get it open and closed during wet conditions.A lot of times with those older latches, you're not going to have as much pressure on the door because of simple wear and tear on your hinges themselves. With this new one, you're going to have more than enough pressure with the cam style latch to be able to get it in place and our door's going to seal very, very well. And then when paired with a padlock of some sort, your contents are going to be safe on the inside.So when installing, this we did run into a slight issue that is our top two holes lined up for our bottom two we're about a hole off. So we're going to give you some measurements, just you have a better idea of where it's going to land on your trailer.

On each bracket the space in between the holes is going to be about three and a quarter inches. And on our total length from our top most hold to our bottom most hole is going to be about 53 and three-quarter inches. And for our hasp, our holes are going to be about four inches apart. So overall the installation wasn't too bad. We did have to drill a few holes.

You are going to have to provide your own hardware or reuse your old hardware. But with that being said, let's go ahead and show you how we got it done.Now to get our new latch in place, we're going to use the old hardware just to hold it so that we can measure our bottom two holes because they're not going to quite line up with our old latch. So we're going to use the same alignment and mark our new holes and then we're going to have to drill these out and then we're going to use bolts instead of our self-tapping screws that we're in our old latch. Now what we're using here for our hardware is going to be a five-sixteenths carriage bolt that's two and a half inches long in order to get all the way through our trailer wall. With it being a five-sixteenths bolt, we're going to be using a three-eights bit in order to drill out our holes,Now depending on the thickness of your trailer wall, ours is just going to be the sheet metal here, a two by four backing, and then a piece of plywood on the inside.

So our drill bit is going to be more than long enough to be able to reach all the way through our wall. Now we go ahead and take our new hardware and put it into place.Now that we've got our bolts inserted on our top two holes, we'll put a washer, a flat washer, and a nut on the backside of each of our four bolts and then we'll tighten them all. Now on our locking portion, there's nothing wrong with this lock except our new kit is going to come with a new one, so we're going to go ahead and replace it while we're at it. We lined it up with our old preexisting holes and the holes are not going to line up, so we're going to have to drill another hole and we will be able to reuse our old hardware but we're going to go ahead and drill out that hole.Now we're going to be reinserting the hardware that came out of these holes on our old latch because I like how they have a flush-mount design on the inside. If you need to pick up new hardware, go ahead and just pick up the same bolts. They are going to have the same size square as the latch does. And we can go ahead and test it after we've got everything safely secured.Now we can take some gasket healer, or some caulk and fill in any holes that might be still present. So here we're just using some white caulk to patch up that hole.So all in all the installation's not going to be too difficult. It did kind of stink that we did have to drill two new holes for the bottom, but it may not work out like that for you guys. All in all, I think it's going to be a really great product and it's going to be a great replacement for your trailer.

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

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.


Comments
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.

Working great. Would order from you again.

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!
-- comment by: Scot S - 03/05/2015

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.

Hi I am a high school metal shop teacher. My students built a 18 foot cargo trailer for our trap and skeet shooting club. the ramp needed a secure locking system and this assembly fit the bill perfect! Thanks from the student of Mr Boyces Metals class.

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.

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.

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.

The Bar Lock Assembly is top quality. Well built and strong. Etrailer.com's customer service and shipping and follow-up is some of the best I've experienced. The shipping cartons are really sturdy and my stuff has always arrived in perfect shape.

My shed door didn't close well and the shed was becoming a haven for wasps. After searching for a door latch that would seal the door I found your website and you had the perfect product for my project. Your site was easy to navigate and simple to use. I was happy with the email updates on the shipping status and the latch arrived in good time and in good condition. This might be the first time your trailer parts were used to fix a shed, so I'm including a picture. All in all, a great experience.

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!

Added this bar lock to the side door on my 6X10 Wells Cargo enclosed trailer. Easy installation and it works great. Fit is a bit snug, but it has not been a problem. Some aluminum shims under the hinges would provide a looser fit, but really not necessary. Price is a fraction of what it would have cost to get this bar lock from the trailer manufacturer. This lock provides a substantial increase in security for the trailer and is really well built.

  • Tips for Installing Trailer Cam Door Style Latch on Trailer With Door that Isn't Flush
    To use a cam door style trailer latch on a trailer door that sticks out 1 inch past surface you'd want to use a spacer behind the latch mechanisms that attach on the door. I'd also go with a setup like the part # PLR258-002-SS which allows you to provide your own bar. You could attach the latch on top of the bar so that you get more offset as well.

  • Will the Lock Side-Door Bar Lock Assembly Fit Over a Door Latch
    That would depend on several different factors such how much the door sticks out away from the trailer and how much the handle sticks out away from the door. However, if you do run into clearance issues you can always install a spacer on the hinge for the Lock Side-Door Bar Lock Assembly part # 305736 which you can see in the attached photo. We don't carry these spacers but I am certain you would find something at your local hardware store. Unfortunately, there wouldn't be a way for...

    Typically you see lock/latches like the part # 305736 installed at the rear of a horse trailer. The assembly of this is 36 inches long. For a 55 inch long version the part # 3057-55 would work. My parents had several horse trailers and every single one of them used this style. I pulled up several pictures of 1997 Circle J horse trailers and they all looked like they were using a shorter latch like the # 305736. If you need a different style feel free to email me back with pictures...

  • Type/Size of Hardware Needed to Install Side Door Bar Lock Assembly #305736
    Although there are no hardware kits available to install the Polar Lock Side-Door Bar Lock Assembly # 305736 we have found that you can use 5/16 inch carriage bolts along with some nuts and washers that are compatible with the bolts. All of which can be acquired at your local hardware store and should be bought with either a galvanized finish or stainless steel.
