Jack-in-a-Box Slide-Out Stabilizers, Set of 2 is rated 4.8 out of 5 by 46.
Rated 5 out of 5 by from Better than expected I bought two sets. One set for each of my back slide outs which expand the living area. I have been RVing for 11 years now and I wish I had purchased these sooner. They really do the job and stabilize the 5th wheel and prevent the side to side motion. I have the 6 point auto leveler's which provide good stability. But adding this product took the stability to another level. No more swaying in high winds, it limits the bouncing and rocking when someone walked or enters the RV. Also very easy to install and take down, so it can be used easily even if you move a lot as I do. I am really satisfied with this product. I would recommend to anyone.

Rated 5 out of 5 by from Slide-Out-Stabilizers works great with movement We are now full timers and used the stabilizers on our 2007 Montana. We have 4 slides but have put the set on the biggest slide. We have only had the stabilizers for a short time but already feel the difference with the movement. We have a washer and dryer and it use to shake pretty bad. This has helped a lot. It just feels more solid when you walk. I think it will also help over time to keep the slide for sagging. We are going to purchase sets for the TV/desk area and the kitchen slide. I would give this product a A+... Debbie in California (formally Missouri)

Rated 5 out of 5 by from They do as advertised We have a slider on our Rockwood hybrid and while moving around inside, it always tended to shake. These stabilizers keep the unit stable now. They are easy to adjust in height. There is a handle welded onto the nut that lifts the jack up and down. It can't be removed unless you take the unit apart. They're good investment. Made well and will last some time. Be aware they are not for lifting. Just snug them up against the slider rails. If using them in soft soil, you may want to put a wooden block under them to keep them from sinking in the dirt/mud.

Rated 5 out of 5 by from I feel safer with them then without them. I am a rather large guy 350 lbs. My buddy who ones an older model trailer told when he bought it the pop out bars were bent by the previous owner because they did not use stabilizer. My wife and I just purchased a 2007 Skyline 30' Weekend and I didn't want to experience the same problems down the road. So I purchased the stabilizers. They are great and a snap to install. I can now comfortable sit on the couch or dinning room table and not have to worry about my weight affecting the pop out. Great product! I highly recommend it to others.

Rated 5 out of 5 by from Jack-in-a-Box Slide-Out Stabilizers After reading all of the reviews, I purchased a pair of these for my new 2019 travel trailer slide out. I am purchasing them for exactly what they are intended for; to stabilize my slide out. We have a seasonal campsite and leave our slide out open for extended periods of time. I want to be sure my slide out is securely stabilized so it does not get damaged since this is a brand new 2019 travel trailer. Also, I purchased them near the end of the season so I got them for almost half price.

Rated 5 out of 5 by from Great product These jacks worked great for our slide-out. We were pleased with the merchandise and the shipping was fast.

Rated 5 out of 5 by from Don't hesitate! We have a 2013 Keystone Sprinter 320 BHS travel trailer (8200 lbs.) with two driver side slide outs. - They work better than I could have expected, no more wiggles! - Light weight, solid in construction, look great and VERY easy to use. - Our slide out arms are 29 inches up from the ground. These reach no problem. - Out of all the things you think you need but aren't sure they will work... THESE WORK! - Great product, great price with the desired results.

Will this product damage the gear or teeth on the slideout

I have a toy hauler with one slideout
Asked by: Ladmo
As long as the stabilizer is not over-torqued, no damage will occur to the slide out gears/mechanism.

Have seen this model with handle that swings down when not being used. is that a new style? if so, can those be purchased?

Asked by: barry
Yes, the 'new' style jack-in-a-box has a folding handle rather than a welded on handle as displayed in our product images. When SKU#11253 is ordered, the current model with the folding handle will be sent instead of the previous generation with the directly welded handle.

how many do you need for a 16ft travel trailer

Asked by: halosmom
Ideally, use a set(2) of the stabilizers per slide out. Increase the quantity to match the number of slideouts as this product is sold as 2 stabilizers per package.

Can this product be use to stabilize a pop up camper king size bed.

Asked by: Anonymous
While not originally designed so. If height from the ground to the mattress is less than 34" and there is a solid piece of frame the stabilizer can press against, yes it can be used for this scenario.

How many per slide out?

If this comes in a 2 package set, can you use one per slide out in the middle of the slide out? Or do you have to have one support on each side of the slide out?
Asked by: Anonymous
Ideally 2 of the stabilizers are used on a single slide out. Each 'Jack-In-A-Box' is placed as far as possible to the outside corner of the slide out room. On smaller slide outs placing a single stabilizer in the center should work okay, but optimal performance requires 2 units regardless of room size.

Where do you attach them under the slide out?

We have 3 slide outs which stick out 39 away from the 30ft V-lite Flagstaff 2013 travel trailer. Trailer has a lot of bounce.
Asked by: Anonymous
These supports are to be placed under the slide-out frame.
