Video Transcript for JR Products Deluxe Compartment Door Thumb Latch Review

What's up everybody. It's AJ with Today, we'll be checking out this replacement thumb lock for your compartment doors from Jr Products. Now you can see we've got quite a few thumb locks on our camper today, and they're same on the other side, but sometimes they're going to go out and you're going to need to replace them. If they get like a little rusted on the inside and they're hard to turn, that's going to be a pain to do and deal with every time you go to open the compartment.Let's show you how to replace it. Measurements are really important to make sure you get the right thumb latch for your door.

So you have four different options here. We've got five eighths, seven eighths one and one eighth and one and three eights. So measuring from the lip to the outside is going to determine which one of these we actually need.We want plenty of these threads. The measurements go from here to the outside. It's showing you how many threads you're going to have to make sure it fits all the way out of here and the blade can catch and keep your door closed.

So let's measure it and see what we need. Looks like it's about seven eighths. So we'll go with the seven eighth one install that, and it should be good. The blade should catch here and keep the door closed. First step in replacing our thumb latch is getting rid of the old one.

So we're just going to loosen the screw here on the back and turn so it goes in its upright position and it catches itself as you turn it out. Now unscrew it and take off the latch and then we'll need to release this nut here.So we'll back that off with a ratchet, seven eighths. Remove that then push through. Push on the core itself and pop it out like that and we're ready to add our new one in. We're going to put the weather strip on our lock before we put it where the old one was.

Go ahead and push it through. See, it's flat on that side with the weather strip protecting it. We'll come back here and we'll let nut back on there. It looks like it's nice and tight. So then we'll go ahead and add the latch. I'm going to put the square here in the square of the latch and then add the screw on top. You can get a screwdriver and tighten it down.Must test out. You see, even using this latch this is still locked in place so it's keeping the door shut. A couple more things about the latch itself, it may not go around the lip of the inside to allow you to fully turn it. So there's a couple of things you can do about that. You can put the flat latch that comes with it too. So it comes with the one that has a little bit of a bend. You are going to flip that the other way, that way it comes out a little bit more then goes in a little bit more and they also come with a flat latch. So you can try that to see if that gets around there and if neither of those work, you can pry it out yourself with a screwdriver. You just put the screwdriver in, add some pressure and it'll bend it just a little bit to where you think it will fit around the inside lip.That's all it takes to install your thumb latches on all your doors here. It was pretty easy. I really only needed two tools to do it, the screwdriver and the ratchet. Just make sure you measure your doors and you get the right size. So you get it right the first time that does it for our look at the thumb latches..

The door latch was an ideal replacement for my 2019 Reflection 337RLS. Only issue, was the delay here in the Houston area with the USPS.


Great alternative to key locks. I replaced all mine with these thumb latches.


Excellent product and as described. Delivery was a day late but that was probably attributed to USPS.


The order arrived sooner than expected and was exactly what we needed!


Great , helpful products! Great service, your right on the order & fast!


Exactly what I needed and fast delivery.


A simple part that sometimes fails on older RVs.These latches solved my problems with keeping storage compartments tightly closed. Easy to install with the help of the company's online video. Now a year later all my compartments are snug and safe. They are better than the original equipment that came with my Roadtrek.


Did what it was designed to do.


Even with a wrong zip code I received my package on the day that it was scheduled to arrive. Thank!


Just what I wanted and ordered. Can't ask for anything more.


These are nice locks. I'm ordering more.


The drawers in our Winnebago travel van would sometimes pop open when driving on the winding roads of West Virginia and Pennsylvania. These latches will provide a positive stop in addition to the friction latches. Problem solved! Thanks etrailer!



We traded the van for a roomier Winne ago View but the latches worked fine as long as we had it.


Door Latches came packaged safely and arrived in a timely manner. George J. kept me informed as to the status of this order throughout the shipping process via email. Excellent Customer service!!


Perfect replacement for the corroded latch. Nice finish,looks great


Exact replacement I needed to replace my 8 year old coroded thumb latch on our Sunset Trail travel trailer (Matter of fact...this ones even better!)



Still like new!!


Perfect fit, easy to replaceā€¦ works like a charm


The latch is sturdy and well made. Ensure you note that the back latch is either straight or bent in two directions to allow fitting correctly on a variety of doors. I painted the part of the thumb catch red to indicate the lock side. Makes it much easier to remember what side needs to be down to engage the lock.


Just installed thumb latch. Easy after watching video. Suggest watching video prior to ordering to make sure you get the right barrel length. The unit came with two latch arms, straight and offset which is good idea, but the arms were too short to hold compartment door closed. Was able to salvage old arm and with video help bent it slightly for good grip. You might want to add comment about latch arm length. As usual, very pleased with etrailer parts, info and good delivery.


Super easy to install and still work as good as new one year later.



Bought two, still work.


Good quality. Exactly what I needed.


Work great. Install easy. robust prod uct.


Locks work great! I am using them on a wood planer cabinet to keep the drawers closed when the vacuum is on.


PERFECT! Just the right length. My "basement door is thick and these fit perfect and eTrailer got them to me quick.


It's great having my own special keyed locks, (not the factory run of the mill ones), and all are keyed alike. Not guaranteed safety, but it does feel a lot better.


Part was shipped quickly and exactly what I wanted. Thanks guys!



It is working great. I haven't had any problems since installing.
