Great product, just what was needed for an extended winter stay in a warm climate. Easy to install and solid support for heavy slide out.


Arrived faster than expected, packaging mangled but supports appear to be fine. Haven't had opportunity to use them yet but from reviews they should solidify camper slide. I'll do follow up review after I've had chance to use em.


The Product appears to be what I need to add extra support to my toy haulers doors.
Not impressed with the shipping company, it was a miracle that the 2 items stayed inside of the box.
The attached picture shows you how they arrived today.


Fixed the issues we were having


Would never use anything else


I recently purchased a 1/5 wheel travel trailer with 5 slides. It was recommended that I should put slide supports under the bigger slides. After researching, I decided the Ultra-Fabs would do the job. I received them on Thursday and installed 2 sets that afternoon. I followed the guidelines and set them in less than 30 minutes. Friday afternoon I installed the rest. I know they did a good job because my wife's first comment was "the trailer doesn't bounce when you walk across the floor". That was the best test. She didn't know what I was doing under the trailer.
They were easy to install, 1 plastic leveling block, the support, and a short level.
Set the block under the slid rail at the outermost end, hold the support on it and pull the top up until it touches the rail. Holding the top against the rail with the ears on the sides of the rail. With 1 hand, push the white button and slide the lock ring down against the bottom housing and release the button. Plumb the bottom housing with the level. Give the lock ring 1 good turn after it is snug and you are finished.

A year after installing the Ultra-Fabs, the only problem Ive encountered is the ground settling under the Ultra-Fabs. 1to2 turns on the lock rings cured the problem of them being loose. Ive recommended these Ultra-Fabs to many RVers Ive encountered over the past year.

These are extremely durable and quick to install. We use them on a Lance 1575 slide out and they really stabilize the unit. Definitely a worthwhile investment.


Glad to find these! Keeps our slideout nice & level & prevents sag. Keeps stress off of 3 inch bolt underneath slideout that had broken off previously before getting these supports


I'm giving a 4 out of 5 because of a known manufacture defect. Some of them contain a nut that is defective and will not allow the gear to have pressure applied.

Etrailer to the rescue!! and they did :-)

I was very excited last weekend when I went out for the first time this year. Cleared a spot from the snow covered ground, placed a pad and then the support, pressed, lifted, two or three turns and done. LOVE IT. on to the next support, did the same thing but the support wouldn't stay up. Everytime I tried turning it it would skip back down. I looked around but couldn't find anything wrong.

I contacted once I got home and within an hour, they had contacted Ultra-Fab, sent me instructions on how to replace the defective part and I got an email the next day from UPS saying the item shipped!!!!!

Well done etrailer and Ultra-Fab..
I dropped 1 start because I think for the cost of a nut, Ultra-Fab should be sending them out to be shipped with the item instead of waiting to see which ones are failing.. not too big a deal, I am impressed with the quick response but more impressed with how quickly etrailer handled it all.


This product has been just ok. The plastic tightening should not be made of plastic, they slip sometimes. Otherwise, the product works as intended. We live full time in our RV and these are consistently in use. We do appreciate the way the trailer feels when the slide out Jack's are in use, feels solid and eliminates 80% of the bounce as people walk around or grandkids jump. We would reccomend this product type to our friends. We love Etrailer and the ease of finding the products we are in search of.


Great product. We use these every time we camp. I like the fact that my slide out is secure and supported. It provide extra support for the entire trailer. Would highly recommend this product!!!


They do as advertised just wish they had the ability to lift up the slide to help level but you still need a jack to level and then set supports.


With my slides all on one side of the trailer these jacks keeps my trailer from leaning to one side also it helps sturdy my trailer in high winds. These jacks work great.


I purchased my rv in 11/16 and found not having any suport for my slide out has really made my rv un stable to walk in and also sitting at my dinette or couch very wobbly. I just installed the 2 stabilizing jacks and WOW what a differance already!! :)
I am very glad I purcased these jacks for my rv.
Thank you :)
S Eddy :)


Love them great product


They look great going to try them tonig ht


Slide out supports were exactly as described, packaging was great and it was received 2 days earlier than expected.


Easy ordering... Fast delivery... The slide-out supports are well made/heavy duty, easy to use and the compact size is great for on board RV storage.


Received the slide out support posts that I ordered in a timely manner. This type is much easier to install then the type with the rotating bar that hits the inside fender of my RV.


These are very good product. We live in an RV fulltime and these work really well to sta alize out slide out. Very much recommend and the price was great!


Arrived quickly. Installed easily and a perfect fit. Recommend!

Still a fabulous product. Its a very positive purchase.
Starla - 07/15/2019


Adds stability to the trailer when the slide is out. These are really easy to adjust and get set up! A definite must if you have a slide!


Tried them out this weekend and they were a great success!! They definitely help stabilized the slide outs and the trailer itself.


Just put the jacks on my trailer and they work great. I no longer see any sagging.


Ordered these for our slideout to stabilize it as we leave it out for several months at a time. They arrived quickly and were super easy to install. Looks like an excellent product.

    The Ultra-Fab Slide-Out Supports for Motor Homes # UF19-960002 referenced in your question are designed to stabilize a motorhome slide-out by supporting their bottom frame rails. They are rated for this purpose so I cannot be sure if they will work properly in a different application. When used together, the two included slide-out supports have a total weight capacity of 1,400 pounds. The U-Channel inside bracket width is 4-3/4 inches with a front to back measurement of 2-1/2 inches....

  • What are the Dimensions of the U-Shaped Support on the Ultra-Fab Slide-Out Supports

The height is 1-3/8 inches and the front to back measurement is 2-1/2 inches. I have included a picture showing some of these measurements for you.

  • Slide Out Support For Travel Trailer
    The first step to choosing the right slide out supports for your camper is to measure how high off the ground your slide outs are when your camper is on level ground. Slide out supports are adjustable to fit different heights, so even if you park on uneven ground, the supports will still fit under your camper as long as you choose your support with your level-ground height in the middle of the range. For weight capacity, the slide out support only has to support the weight of your slide...

  • Do Slide Out Jacks Help on RVs with Slide Outs
    While some manufacturers will say that a slide out jack isn't needed we've found that they do make a noticeable improvement to overall stability when parked which means a more solid feel when walking around in the RV and also less chance of getting woken up at night due to movement. We have a few sizes that you'll have to measure your RV to determine which would work best. We have the part # UF19-960002 which is 21 inch to 37 inch, part # UF19-960001 which is 16 to 28 inch, and we have...

  • How to Determine Correct Slide-Out Support For Motorhome
    I believe you are referring to slide-out supports, and it's pretty simple to choose the right one. All you need to do is measure from the ground to the bottom of the slide out track to get the correct height; the photo below shows where you want to measure. Once you have that, just pick the correct height, and there are three to choose from: - 16" to 28": Ultra-Fab Slide-Out Supports # UF19-960001 - 21" to 37": Ultra-Fab Slide-Out Supports # UF19-960002 - 26" to 47": Ultra-Fab Slide-Out...

  • Recommendation for 5th Wheel Trailer Slide-Out Stabilizers
    Using Ultra-Fab Slide-Out Supports, # UF19-960002, would be a good choice because they are adjustable from 21 to 37 inches which covers the range you have provided (26-1/2 on one and 30-1/2 on the other). If you wanted to put a leveler block underneath I recommend the Ultra-Fab levelers, # UF48-979051, because they are much more reliable than say a block of wood would be. I have included a link to a video review for you.

  • Recommended Products To Stabilize Grand Design Reflection Travel Trailer When Camping
    For your Grand Design Reflection 312BHTS I recommend the Ultra-Fab Slide-Out Supports # UF19-960002. Since your Reflection has the 2 opposing slides that carry the weight of most the kitchen and the seating areas the trailer is virtually teetering on itself with the weight hanging over the sides of the trailer. These supports will allow you to stabilize that additional weight where it matters at the edge of the slide rather than at the frame which is inside the wheel footprint. Be sure...

  • Looking for Jacks to Stabilize a Slide Out on an Older Travel Trailer Camper
    To support your slide out of your older camper, I recommend an Ultra-Fab Slide-Out Support instead of heavy duty jacks. The Ultra-Fab supports are sold in sets of two and come in three sizes depending on your trailers ground clearance when the slide out is extended. The difference in the three sets we have is the height. The # UF19-9600001 has a range from 16 to 28 inches, the # UF19-960002 has a range from 21 to 37 inches, and the # UF19-960003 has a range from 26 to 47 inches. All...

  • Hitch Installation Support Jack for Stability
    To have a support, we normally use a second set of hands because that is the safest and easiest option. When another set of hands is not available, an option is to use the Ultra-Fab Slide-Out Supports for Motor Homes - 21" to 37" - Qty 2 # UF19-960002 to adjust the height of the hitch and support it. I recommend using straps like # IMF12637 to also secure the hitch to the supports if you use these supports.

  • Operation and Sturdiness of Stromberg Carlson Camper Jack # JB-20 when Fully Extended
    I was able to go out to our warehouse and test out the strudiness of the Stromberg Camper Jack # JB-20, and check out the handle for you. I found that the handle does rotate down so that it won't stick out after you have set the height of the jack. I also found that they are very sturdy once the handle and nut are tightened to the base, even at the fully extended height. I have to tell you though, after spending the time to fully extend it and rotate the nut to the bottom, I had some...

  • Fitment of Slide Out Stabilizers on a RV
    Good news, I can help you understand why you would want these stabilizers for your RV.

They are designed to be used with your other stabilizers on your RV for an overall stabilization of the unit when parked. There shouldn't be any room for the stabilizer to have movement therefore no banging against parts if installed properly. If you are concerned about...

  • Recommended Stabilizers for RV Patios
    The only supports we have for a patio or slide out are the slide out supports like the Ultra-Fab # UF19-960001 or # UF19-960002 if there is a frame rail. You could alternatively use a scissor stabilizer jack like # TJSC-24 or # JSC-30-IND. The only other option I can think of is to use the Brophy Cable Camper Jacks - 57" Max Lift Height - 3,000 lbs - Qty 2 # CJ41 as a stabilizer.
