Review and How to Install the Polar Hardware Lock Side-Door Bar Lock Assembly

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.
