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
-- comment by: Steve S - 12/09/2013Steve,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.
-- comment by: Michael - 12/27/2013Working great. Would order from you again.
Michael K - 10/24/2014Is 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 - 03/05/2015by: Kenneth 12/07/2021
Trailer I bought didn't have it and I wanted it. Only regret is you don't have mounting hard for it. I'll get it local.

Mounted and working GREAT!

E-trailer did an excellent job of shipping and handling of the product sent to me. It is of high quality and should last for years. It was delivered when they said it would be and I have installed it. Quite happy with it but wish that they would stock a 45" bar lock
Comments
The latch assembly is exactly what I needed for the shed that I built to house my small refrigerator. The critters or other unwanted cant get in.
Les S - 08/31/2016by: Maxx W11/04/2014
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.
by: Bob W.07/09/2014
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.
by: Marty 01/21/2023
Great product and delivery was quick and easy to track!
by: Aram07/06/2022
These things are bulletproof. I use my trailer 6 days a week and open it about 20 times a day. These latches have worked perfectly. I highly recommend them. Easy to install too
by: Brad02/04/2023
Product was great and in stock. I ordered this on Friday and it was not going to ship until the following Wednesday with a planned Saturday delivery. I called on Monday to ask why it would take 5 days to get it off the shelf and out the door for shipping. The Customer Service person was not very informative and basically said it was what it was. However, after my call they ended up shipping on Monday and I received on Wednesday. So all ended well but I didn't understand the need for drama. If it is going to take 4-5 days to get shipping started, then state that in the order so customer sets the correct expectations.
In the end, I'm happy with the product - I'd buy again, but I think I would call it in the next time rather than ordering through my account.
by: Rick 07/20/2022
Installed easily with carriage bolts purchased from Ace. Had to bend the handles on a bench vice but that's not a problem with the product just the application of where it is on my trailer.Product works awesome.

Always have good luck with your products

Great product! I wished they offered these in different configurations.
by: Lawrence01/18/2023
It was easy to install, replacing a broken one, and haven’t had any issues.
by: David H09/11/2018
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.
by: Ed D.01/07/2014
here is a pic of the trailer I built, used the products from your place. started with a simple
utility trailer, and build this enclosed trailer.
Comments
Ed- awesome build. Im building something very similar. Where did you get the trim for the door so it can seal? Also what about the larger top trim?
-- comment by: Ryan - 03/28/2016by: Greg05/22/2018
My trailer didn't come with one so I was always worried about the side door coming open. Not anymore!! This item is perfect for what I needed, easy install too. A LOT cheaper price then expected! Arrived sooner then was told.
Comments
Loved your product! Easy to install, great price, and arrived earlier then expected! Piece of mind now going down the road. That side door is NOT coming open! Ill be back!
-- comment by: Greg - 06/11/2018Perfect! No issues....its strong and smooth operation....and PEACE OF MIND my sidedoor will NOT come open driving 65 on the highway.
Greg - 05/22/2019by: Mark I07/18/2015
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.
by: Wally M03/24/2014
Came as described, and in the time frame described(less than actually). Good customer service!
by: Eulitt E07/22/2013
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.
by: Shaun04/23/2022
Good product. Only thing is mounting hole is 5/16 carriage bolt. Not 3/8. Can’t really complain.
Comments
Our product page says that the diameter of the mounting hole is 3 8ths. Most drill charts recommend using a 5 16th bolt for a 3 8ths mounting hole.

See what our Experts say about this Polar Hardware Trailer Door Latch
- Does the Redline Lock Assembly Require a Metal Backing Plate Or BraceThe 36 inch Trailer Door Bar Lock Assembly # 305736 does not come with installation hardware or specific instructions on how it installs. The install will vary based on upon the trailer. Most trailer doors are wood and would need to have holes drilled through them and then use nuts and bolts to attach the # 305736 to it. A backing plate for this assembly is not required or included, but if you used big enough washers to distribute the load you should not have a problem
view full answer... - Is 36 Inch Lock Side-Door Bar Lock Assembly # 305736 Available in Right Hand and Left Hand ModelsThe Redline 36 Inch Side-Door Bar Lock Assembly, # 305736, can be used on the right and left side. The image on our product page shows it in the left hand orientation, but it can be used on the right hand side by flipping it upside down. Check out the photo that I attached.

- Ramp Door Lock Assembly Recommendation for an Enclosed TrailerIf you were to mount the 36" Lock Side-Door Bar Lock Assembly # 305736 on the edge of the corner of your trailer the handle could swing around the corner beyond 180 degrees as there is not a stop in the hinges of the lock. So yes, this could swing 270 degrees from the mounting plane so it should work well for you.
view full answer... - Is the 36 Inch Lock Side-Door Bar Lock Assembly, # 305736, AdjustableThe Lock Side-Door Bar Lock Assembly, # 305736, is designed so that when it is installed, it pushes the door tightly closed. The unit is not adjustable. Attempting to bend or heat the components could compromise the structural integrity of the unit.
view full answer... - How to Install a New Side-Door Bar Lock Assembly # 305736Installing the Hinges on your Side-Door Bar Lock Assembly, item # 305736, is pretty much up to you and the construction of your trailer. You will need to purchase appropriate hardware to install the Side-Door Bar Lock that you purchased. It is best if you can find a sound structural support in the trailer framing to bolt the Side-Door Bar Lock to and still allow the bar to make contact with the face of the door. I have posted a photo of the # 305736 Side-Door Bar Lock, installed on another...

- Is Hasp Included With Side-Door Bar Lock AssemblyYes, the hasp - or keeper latch - is included with the 36" Lock Side-Door Bar Lock Assembly # 305736. The only thing you will need to get separately are is the mounting hardware, which will be 5/16" carriage bolts and matching washers and nuts. I have added a link to a video review of this assembly for you to check out as well.

- Type/Size of Hardware Needed to Install Side Door Bar Lock Assembly #305736Although 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.
view full answer... - Replacement Plastic or Rubber Coating for Cam Door Lock HandleThe only grip/cover we have is the Replacement Rubber Handle Grip for Cam Door Lock Handle # FVH200. This is 3 inches long by 2 inches wide and 1/4 inch tall. I've attached a photo to assist.

- Hardware Needed for 36" Lock Side-Door Bar Lock Assembly 305736To install the 36" Lock Side-Door Bar Lock Assembly # 305736 you will need 5/16 inch diameter carriage bolts to secure the latch to the trailer with nuts and washers. You can find these carriage bolts at your local hardware store.
view full answer... - Hardware Needed To Install 36 Inch Lock Side-Door Bar Lock AssemblyTo install the 36 Inch Lock Side-Door Bar Lock Assembly # 305736 you will want to use carriage bolts, nuts, and washers. There is not a part number that includes this hardware for # 305736. You will want to use 5/16 inch carriage bolts to secure the latch to the trailer. You can find these carriage bolts at your local hardware store.
view full answer... - What Does the 36Yes, the 36" Lock Side-Door Bar Lock Assembly # 305736 comes with everything except mounting hardware that you would need to provide. It comes with pipe, brackets and hasp. Check out the review video I attached to see all of the parts laid out on our demo table.
view full answer... - Will the Lock Side-Door Bar Lock Assembly Fit Over a Door LatchThat 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 me...

- Replacement Handle Recommendation for Lock Side-Door Bar Lock AssemblyFor just the handle of the # 305736 you would want the part # 158-100. I attached a review video for this handle for you to check out as well.

view full answer... - Why Doesn't Hardware Come with Slide Bar Cam Door Latches on TrailersWe dont' have a hardware kit for the cam door bar locks. Reason being every application is a little different so the same hardware kit wouldn't work for most people. You'd want to grab the best sized carriage bolts at a local hardware store for your door.
view full answer... - Does 36 Inch Long Side-Door Bar Lock Assembly Come in BlackThe only color available is the standard steel color for the 36 inch Side-Door Bar Lock Assembly # 305736. This lock assembly is zinc-coated to protect against corrosion, and though it is possible to paint it, you will need to use specific primers made for the job. I have added links below to a couple video reviews and installs for you to check out as well.
view full answer... - Is Installation Hardware Included with the Polar 305736?With the Polar Hardware Side-Door Bar Lock Assembly # 305736 being zinc plated, you will want to go with zinc plated hardware as well. Though this does not include the hardware, we generally recommend using the existing hardware if you are replacing an older assembly. If this is not the case, or if the existing hardware is not in good condition, we recommend using 5/16 carriage bolts, lock nuts, and flat washers. This isn't a size that we carry, but can easily be found at most hardware stores.
view full answer... - Rear Door/Ramp Latch Placement for Horse TrailerWhere you install the latch depends on where you locate the pipe and handle of the Cam-Action Lockable Door Latch item # 305736 on the opposite door. These components are typically centered on the back doors but you will want to install the latch last.
view full answer... - Can Pipe of Cam-Action Lockable Door be CutYes, if you like you can cut down the pipe of the Cam-Action Lockable Door Latch w/ 36" Pipe for Enclosed Trailers # 305736.

The width of the mounting bracket for the Cam-Action Lockable Door Latch w/ 36" Pipe for Enclosed Trailers # 305736 is 2-1/4" while the distance from the center of the mounting hole to the inner edge of the bracket is 1/2" (see attached photo). I've also linked some review and installation videos for you to check out!

- Are Redline and Polar Cam-Action Lockable Door Latch 305736 the Same ThingThe Cam-Action Lockable Door Latch w/ 36" Pipe for Enclosed Trailers # 305736 from Polar is the same thing as the Redline 305736 like what you're asking about. I'm not sure why the name change but it has the same specs as you can see in the linked videos.
view full answer... - Does a Pipe Get Welded to the Cam Ends of the Universal Cam-Door Lock, # 383200First, the Universal Cam-Door Lock, # 383200, does not come with the pipe. You will need to provide a 3/4 inch diameter pipe. I would use regular steel because it is easier to weld then galvanized materials. The handle gets welded to the pipe but none of the other parts. I have linked a video review for you. If you want something similar that includes the pipe you can use # 305736.
view full answer... - Where Can I Get a 3/4 inch Bar to use with the Lock Side-Door Bar Lock Assembly # 383200You will need to go to a hardware store to get a 3/4 inch inside diameter pipe to complete the installation of the Universal Cam-Door Lock for Enclosed Trailers, item # 383200. Some welding is required for installation of this kit. We also have the 36 inch Lock Side-Door Bar Lock Assembly, item # 305736, that is ideal for use on trailer side doors that may be smaller than rear doors. This item is complete and does not require welding for installation. Hardware will need to be provided...
view full answer... - Cam Door Lock Kit Recommendation to get a 45-1/2 inch Long Cam Door Lock for TrailerSince you are looking for a cam door lock that is 45-1/2 inches in length your best option would be to get the Universal Cam-Door Lock for Enclosed Trailers # 383200. With this kit you will be able to select the exact length of pipe to use from your local hardware store so that you get the exact length of door handle you need. You will need to use a 3/4 inner diameter pipe.
