Super heavy duty and easy to install.

FANTASTIC!!!!!! That’s really all that needs to be said about this transition plate, but that really wouldn’t be much of a review now would it. I just installed the transition plate on my trailer and the installation process is very simple and straightforward. The quality of this transition plate is top notch. In my opinion, this is the best option on the market for a transition plate of this quality! I only use my trailer to haul a John Deere riding mower and a motorcycle from time to time and this plate makes it so much easier to load and unload both of them. There was no flex in the plate at all loading either one of them. Just keep in mind that this is made of solid steel, so yes it is going to add a little bit of weight to the rear door of the trailer and it is noticeable when lowering and raising the door. Shipping was extremely fast. I was actually surprised how fast it was shipped. Great job etrailer!!!

I own a luxury mobile Teppanyaki private chef company we use custom NSF commercial wolf griddles for cooking. I’m talking about over 500 lbs of weight each grill. This trailer plate was one of the best purchases I’ve made for my trailer. Although is heavy in weight, it’s heavy duty and can handle the weight of our equipment. Install was very simple. I think it took me less than 60 minutes to install by myself. An experienced person would install under 30 minutes. A happy customer.



by:

We have these on most of our box trailers.
Great product!



by:

Easy to install and very durable. We are a portable church based in south alabama and currently load and unload equipment every weekend. We have a 28ft and 26ft trailer and about to purchase a second one.



by:

Got the items super quick. Don't know why I waited to get these for my trailer. As a DJ I have hated having to lift my carts up over the lip of the ramp. These went together very easily and had both installed in about half an hour. Looking forward to using these soon on my next event.Photos show installed and ramp up.



by:

The only reason for 4 stars is I followed the instructions down to the letter, and by doing that, the transition plate flexes a little bit in the middle of the plate and gets hung up on the trailer door when trying to flip it back over to close the door, looks like I need to move the transition plate up about 1/2 inch to avoid hang ups with the plate. Plate seems to really well made.



by:

I had a great experience with ordering transition plates for my trailer. Shortly after ordering, I was promptly notified about the status of my order by Brandon with etrailer. What I like most about the plate is that it is well-built with solid metal materials which will help with safely loading and unloading heavy items.



by:

The ramp is built very well, super strong for rolling motorcycles / tool boxes or just about anything into the cargo trailer. the only issue I did not account for is the extra weight the door has now because of the ramp, it will require more strength to close the door. (FYI)
So if you want the best ramp for your trailer I highly recommend buying this product. Install is straight forward just line it up and screw it on to the trailer ramp and done.



by:

This ramp came exactly as advertised. It arrived in 2 days, which I did not expect and only took 30 minutes to install. It is made of heavy duty steal that I drive my 26" floor scrubber over. It does not show any sign of struggling to handle the weight.

I will be buying more of these for my other work trailers.



by:

the transition plate from door to ground installed and works great problem is the cover plate from trailer floor to door not working at all turned the bolts over close to the hinge and still have a 1 inch gap from the plate to door. Not a good fit at all.



by:

Works perfectly and handles all the heavy stuff we wheel in and out of our trailer without any hickups or snags with smaller wheels or rough terrain.



by:

Excellent material!! Handles my needs perfectly! I have gone over it with more weight and no problem. I would absolutely recommend it's purchase, matter of fact I may buy a second one for the inside lip of trailer as this one is at ramp doors edge to ground contact. No wood conversions compares to this, especially after a hard days work in the rain.



by:

So far I like them a lot. I bought them for my event/ sales trailer for my business. I have run 1100lbs tool boxes and 800lbs tire machines across them and they are working well. Very happy so far.



by:

This transition plate (t-plate) is a heavier gauge than one provided in an earlier cargo trailer. The stamped pattern provides better footing, too. Though a t-plate isn't necessary for hauling cars, we all know that enclosed trailers haul more furniture that anything else! The t-plate gives workers and wheeled-dollies a smooth ingress and egress from the trailer.
Installation was elementary. I used self-tapping #10 x 1.25" stainless steel screws. The panhead screws in my floor's aluminum end cover were removed for a flush mount against the end cover. The t-plate does have sharp corners which I recommend be rounded just a bit with a small grinder, like a Dremel, to avoid scrapes while strapping down a car.
Yes, the price is excruciating. It's one of those deals: they have it, we want it.



by:

Transition plate works great. Easy to size and install. It’s obviously a lot heavier than the stock plywood transition but that alright it’s solid. I’m happy with the purchase



by:

So far so good. I installed this flap at the bottom of the ramp. We use this trailer for Commercial Moving services and rolling 4 wheel Dollie’s up and down the ramp is very easy with this flap. Took all of 10 minutes to install, definitely recommend.



by:

Super easy installation, high quality tread and heavy duty plates. The only thing I don't love is that it doesn't lay flat over the transition. I put some plastic spacers under the hinges and drilled out holes for the nuts and hinge rivets to help alleviate this. Perhaps raising the tongue more would help also.

Product was packaged so poorly that the metal staples scratched the entire length of the extension. Literally scratched through the paint exposing bare metal. I'll have to get it repainted because the packaging was so bad, I can't return it.

It fit perfectly and is very well made

Great product! Easy install!

  • Recommended Ramp Door Transition Plate That Can Handle a Pallet Jack
    Hey Dustin. I installed the Enclosed Trailer Transition Plate item # M368FR on a trailer here when we first got them in and you're good! That plate is single solid piece of steel. It's got a heavy duty piano style hinge that has been riveted and welded to the plate. You're not going to have any issues using a 600 lbs pallet jack with this transition plate. Make sure you watch your fingers when you drop the Transition Plate item # M368FR. It weighs only 40 lbs but grabbing it from one...

  • Plate For Trailer Ramp Edge And Gap Between Floor And Ramp To Allow Wheels To Roll Without Catching
    Great idea, Leo - we don’t package the M-3 plates as a set, but you can just grab two of whichever version you prefer. Many folks use the steel plate # M368FR for the exterior edge where it takes more impact and the aluminum plate # M348FR for the inside gap since it’s lighter to lift with the door, but you can use whichever is better for you. What’s the trailer used for, Leo?

  • Do Enclosed Trailer Transition Plates Come With Hardware? What Bolts Do I Use?
    Hey Corey, good catch - hardware isn’t included with either the # M368FR steel or # M348FR aluminum plates. Most folks just source stainless or zinc-coated hardware locally so they can match what’s already on their ramp. It also depends on the style and thickness of the ramp, so that's why hardware isn't always going to be universal. Pre-drilled holes are already there, so install’s pretty quick once you line it up. I'd use a standard cordless drill or impact which would zip the screws...

  • Is The Steel Enclosed Trailer Transition Plate Painted Or Raw?
    Hey Sandra! The M-3 steel transition plate # M368FR comes matte black powder-coated, so it’s fully protected against rust and road salt. It’s also welded all the way across the hinge, which keeps moisture out of the seam. You can add a quick spray of rust-inhibitor once a year if you want to be extra safe in salty conditions. It's also good to spray it off every now and then if it gets dirty; that's something I keep forgetting to do on my car hauler trailer. Do you keep the trailer indoors...

  • Transition Plate For 7x16 Enclosed Trailer To Roll Carts Over Ramp Door Where It Gets Hung Up
    Hey Jeff! Yes, the M-3 steel plate # M368FR is perfect for that setup. It’s about 81-3/4 inch wide, so it’ll span your ramp nicely, and the welded steel with a tread-plate texture gives great traction even if your wheels are wet or muddy. You’ll just bolt it to the bottom edge of the door and it folds down with the ramp for a smooth roll-on. If you want something a little lighter but still sturdy, the aluminum version # M348FR does the same job at about half the weight. If you're in extreme...

  • Is There A Transition Plate For Car Hauler Ramp That Has 2" Tall Lip At The End Of Ramp?
    Yep, that’ll still work fine, Joe. Both the Steel # M368FR and the Aluminum # M348FR transition plates are bolt-on and can go on an open trailer - just use through-bolts since you’re mounting into steel. It’ll smooth out that 2-inch lip perfectly and keep smaller tires or casters from hanging up. What kind of car are you loading? That’ll help confirm if you need the steel one for the extra weight.

  • Is the Enclosed Trailer Transition Plate Diamond Plate?
    Hey Adam, I totally understand why that would throw you off. When the photos don’t match, it makes it hard to feel confident you’re getting the right thing. I can confirm the Enclosed Trailer Transition Plate, part # M368FR, is still a diamond plate design. The textured plate you’re seeing in some of the customer photos is actually from a different product, part # e32JR, which has a matte black textured finish. It looks like that review photo ended up on the wrong page, and I’ve already...

  • Steel Transition Plate For Rolling Pallet Jack Over Gap On Trailer Door Ramp
    Hey there Mike; both M-3 plates are built heavy duty, but they don't really have a weight rating. They use a 3/16 inch thick tread plate and come in steel # M386FR or aluminum # M348FR, fully welded with a piano hinge. They’ll take the full load of a pallet jack or rolling toolbox without bending, and the hinge keeps everything smooth. If you’re loading pallets often, I’d lean toward the steel # M368FR for that extra stiffness. What kind of loads are you typically moving?

  • Steel VS Aluminum Transition Plate For 7x12 Enclosed Trailer
    Good question, Patrick - both do the same job, but here are some differences for you to look at. The # M368FR steel is heavier at 40 lbs and better for constant heavy loads like pallet jacks or commercial carts. The # M348FR aluminum is lighter at 23 lbs and rustproof, great if you’re dealing with rain, mud, or coastal air. So, if you’re mostly loading dirtbikes and yard gear, I’d go aluminum. What kind of climate are you in?

  • Transition Plate To Bridge 3" Gap On Wells Cargo Motorcycle Trailer
    Hey Brandon! Yes, either M-3 transition plate (steel # M368FR or aluminum # M348FR) will do the job, but I’d go aluminum # M348FR since it’s easier to trim and won’t rust if water gets in that recessed area. Just mount it across the lower edge of the door and let the hinge float over that 3-inch. If you were hauling heavier equipment, I'd lean towards the steel for a little more reinforcement, but the aluminum is plenty strong for your setup. What type of motorcycles do you have? I always...

  • Can M3 Trailer Ramp Transition Plate Be Used For Inside Gap Between Ramp And Trailer Floor?
    Hey Alan - you can absolutely use the M3 plate at the door-to-floor gap. Many folks run one on the outside edge and another inside for a totally smooth roll-through. The steel plate # M368FR gives you extra strength if you’re using pallet jacks or heavier carts. How big is the gap at your trailer hinge?

  • Can M3 Enclosed Trailer Transition Plate Be Trimmed To Fit 6-1/2 Foot Wide Ramp Door?
    Good question, Chris - yes, both M-3 plates are designed so you can cut them down. Just trim from the outer edge and if you’re using the steel # M368FR, touch up the cut edge with paint to keep it sealed. The aluminum # M348FR doesn’t need that since it won’t rust. Do you already know your door width?
