Video Transcript for Polar Hardware Enclosed Trailer Parts - Doors - 3057-55 Review

Today we are going to be taking a look at the 55 inch Lock Side Door Lock Bar-lock assembly. This can-door 00:00:07 style lock is ideal for you 00:00:09sawing trailer's side doors, that may be smaller than rear doors. It's going to be made from a steel construction. It's going to have rust and corrosion resistant Zinc coating. Your mounting hardware is not included, but we do recommend using 5/16th inch carriage bolts and matching washers and nuts for the installation. The length of those bolts will be dependent on the thickness of your trailer wall. Now I just want to spend some time going over some measurements really quickly with you.

The overall pipe length, that's measuring from one end of the unit, to the other, that's where we are going to get the 55 inch measurement from. If we take our measurement in the distance that we have between the brackets, you can see here that on each bracket we are going to have 2 mount holes. If I measure from the outermost hole, so the outermost hole measuring center on center, that's going to give a measurement of 53 and 3/4 of an inch. The ones that are closest to each other, center on center, that measurement is going to give us a measurement of 47 and 1/4 of an inch. The bracket and hinge area; that's this whole unit, that's going to give us an overall width measurement of about 2 inches wide and the length of that is going to measure about 4 and 1/2 inches. The mount holes on the brackets, these are going to be separated apart from one another on center, by 3 and 1/4 of an inch.

The distance that we have, from the center of the handle to the top 00:01:48 mounting hole in the unit, that's going to give a measurement of 26 and 3/4 of an inch. This does include your handle keeper. It's going to be these two components here, so with the 9 00:02:06 hardware installed this top piece would swivel out of the way. That way, you can lift up the handle and release it. This is actually going to be two pieces; again, its got the swivel design there, that way you can come out of the way and you can remove the handle. You can see here that it does have the center hole, that's going to be the lock hole, if you want to install the padlock.

It does not include the lock but we carry a lot of those here on our website, so if you are in need of one, you can check out some really great options at 00:02:38. The diameter of the lock holes is going to be a 1/2 of an inch. The distance that we have from the center of one mounting hole of the unit, to the center of the other, here on the handle keeper, kind of flip this over to give us a little bit more accurate measurement, that's going to be separated on-center by 4 inches. Again, really nice design on the handle itself. Its got a nice, easy-grip design. Its got that coating on there, so allows you to get a really nice, secure, grip when using the handle. But again, this is going to be a total length if 55 inches and that steel construction makes it very durable and dependable design.

That's going to do it for today's look at the 55 inch lock, Side door bar-lock Assembly.

Exact fit replacement which was easy to install. The detailed measurements provided on the etrailer web page made me confident that this would work without any modifications. Etrailer communicated shipping status which made the whole buying process seamless. 347742

The detailed description and measurements that are included in the product description made finding this product easy and ensured that I was able to accurately measure my replacement needs. The correct product arrived on time, fit perfectly and was in fact superior to the OEM bar latches. I am a very satisfied customer. 211278

The service we received was excellent. Our Bar Locks arrived much faster than expected and were exactly as described. They were installed easily and a perfect fit. The only problem is now the shiny new bars don't match the rest of the rusty trailer. 194592

Item as described, fit perfectly. Also, item shipped quickly and great email notifications. Will order trailer parts again, if needed. Thanks! 525319

Great quality, and a fair price. Shipping is always a detriment these days. Still, it's exactly what I've been needing to secure my instruments. Clearly Etrailer, is seeking repeat customers with there heads up on back orders, and follow up E-mail. Thanks, Bob L. 142316

The item shipped fast in great condition. Installation was easy. My bar was 55 1/2" this was 55" therefore i had to drill new holes for the bottom but really no problem. Very satisfied! 275810



- 3057-55
by:

Product came very quickly. I had two barn doors on a dump trailer that I wanted more support for closing, so I used this instead of a clasp. There is pressure pushing out from inside, and this keeps it solidly closed. Also having the long handle gives a little more leverage to push up and allow it to open with the pressure against it. I would definitely recommend this product to someone looking for a longer, more secure door latch. 367253



- 3057-55
by:

The quality and the value of the product was great. I would have given a n excellent if the hinge holes had lined up with my existing holes. They were off by about 3/8 of an inch resulting in having to move the bar slightly to the right in order to drill new holes in the trailer. A measurement in your description that shows the distance from the top, lower hinge hole to the bottom, upper hinge hole would have prepared me for drilling new holes in the trailer and knowing the bar was going to have to be slightly crooked. Hope it holds up to the test. Thanks for rushing my order through...service was great! 149380

No issues with the product. I did however weld a piece of metal over the latch so thieves can't break it and gain entry, as well as rounded off bolts with a double nut on the interior. I also purchased a big box lock that goes with a solid pin. Without that it only takes a good pry to pop the latch and break in. etrailer has been great to do business with 468241

Changed a front dropdown hybrid camper tent door from screw clamps to these normal door latches for better sealing. Not quite as heavy metal as older latches, but adequate for task and thick enough to weld. Robot welding is beautiful, some spatter berries to remove. Plastic cover plugs on ends were distorted damaged and ugly so I tossed those. Overall good rpoduct and worked well for intended purpose. Good price for the quality received. 397419


Comments

Replaced screw clamp latches on front of a fold out camper with these cam locks. Better seal and more secure. I had to cut and weld to get length I wanted but overall worked well. Still rust free. Needs some oil on hinges occasionally, as to be expected. Would buy again if needed.

Overall a good product. I installed it over an RV style door on my enclosed trailer. Cheap stamping of the latch itself and lack of quality control leaves me needing to dremel out the opening to correct the alignment of the hole so that a puck style lock can be used. A little disappointed here... 486499
