Video Transcript for Paneloc Heavy Duty Spring Latch Review

Hi, neighbor. This is Brad at etrailer and today we're looking at the Paneloc Heavy Duty Spring Latch system that is zinc coated. For those looking for added protection, we also have a stainless steel option. So if you have a trailer that you use on a regular basis, a lot of times we're not so fortunate to be able to store it inside so it sits outside in the elements, which in turn can cause corrosion, as you see. Same with the hardware. A product is only as good as its hardware sometimes, and honestly, the hardware can make a difference of ease of loading or just the overall feel of the quality of a trailer.

Something else you might consider needing new hardware would be adding your own attachments to the back for repurposing a trailer for something. In this case, loading a golf cart. So this bracket itself, pretty simple, two mounting holes. You have a compression pin here that acts as a lock. If you've ever loaded a trailer by yourself, it can get kinda tricky.

A lot of your attachments can get heavy, so you catch yourself in a position while you're trying to put it up. If the pins are down, you're having to do the dance in between 'em. So something cool with that locking system is you can do one at a time, drop down. Same thing. You can load your golf cart, in this instance.

Put this up. I can walk over here, take my time, and boom, one-person system. So something to take in consideration with this kit and something that you'll have to have some forethought before putting it on is, it does not come with hardware. So what we're using since we have a 5/16 hole is a 5/16 bolt, roughly about an inch long. Depending on your situation, your bracket, metal, it could change.

The 5/16 hole, we're gonna put this through. And here we have a flat washer and a nylon locking nut. Nylons are good, especially on a trailer that has a lot of vibration. You don't want that working out and all of a sudden your hitch pin coming out. So we'll get this tightened up. You're gonna need to find a bracket or fabricate your own bracket for your needs if your trailer doesn't have one, so make sure you match the 1/2 inch hole, maybe a little larger. Something that's nice about this pin, as you can see, it's tapered in so you don't have to have a direct shot in, so it should make for an easy drop in. Something else. This construction, it is steel. It is zinc coated. Zinc coating helps protect it from the elements for a pretty long time. It does a great job. So something to think about when you're buying these for your trailer would be left hand or right hand so these mirror each other, so obviously one side will go to the other. But the way to determine that, if you look at the front face of it, see where the pin is It's on the right and that's your right-hand side. This is the opposite side, so as you can see looking at the front, it's on the left. So the product itself has very good feel to it. As you can see, spring deck is good. A little squeaking, but nothing terrible. You may have some binding issues but part of that could be your hole not big enough, your alignment off, so really making sure when you fabricate it on your trailer, you do a good job to square it up. So that's a look at our Paneloc Heavy Duty Spring Latch with Hold Back. So, if you are fabricating your own trailer as this is, or you just want a refresh on the hardware on your existing trailer, having a nice new touch point for something that you use a lot and not having a latch hang up while trying to load is something that's totally worth it. Thanks for watching..

Great heavy duty pins. Now I need to install these to make trailer ramp easier to open and close.


This has worked well. We have used it on our horse trailer saddle rack to hold it in place and it is doing its job


Great jack. The quick release pin to allow it to raise far away from the ground should be how every jack for a utility trailer is.


Just received my spring latches and I am looking forward to installing them and putting them to use. Great service and professional personnel helped through the process of ordering to delivery! Thanks Etrailer!


I bought these latches to replace the pins and hairpins that held the gate on my landscape trailer. Before, I had to remove the hairpin, then pull the pin holding the gate, then find a place to keep the pins so that I wouldn't lose them. With these spring loaded pins, I just pull the pin and turn it so that it locks open, then lower the gate. These are going to so much better than the original pins...wish I'd done this years ago.

They appear to be very well built.

Still working great a year later. So easy!

Easy order process and a very detailed account of shipment information.


good product, no reason why right hand cost $5 more than left hand when you can just pull roll pin out and switch sides.


Excellent product and quick delivery se rvice


Fast shipping, great products


Latch worked great for a custom short tailgate build on a 5x14 trailer. Good quality materials and construction. Very quick shipping as well. Thanks!


I lost a pin on my existing gate locks. I decided to replace both as I did not find an exact replacement. These are much better than my original. Glad I decided to replace both sides.


etrailer had what I needed and got it to me quickly. I will definitely use etrailer for parts in the future.


Nice quality, heavy duty


the product was a lot heavier than I thought it would be and it is a wonderful surprise!! will be ordering them again




well built,great price



Nice quality latch.

  • Maximum Throw/Pin Extension for Spring Latch
    I would love to help but we do not offer the Paneloc Heavy Duty Spring Latch part # F719-172Z105 for left hand or part # F719-182Z104 for right hand with a pin extension of more than 1-1/4". The only option you have to obtain a greater extension would be to go to the next size up which is the Paneloc Heavy Duty Spring Latch part # F720-182Z105 for left hand or part # F720-172Z105 for right hand that has a 1/2" diameter pin with 1-1/2" extension.
