Jack-in-a-Box Slide-Out Stabilizers, Set of 2

Catalog Item # 11253

Stabilize your slide-out to stop swaying as you move about inside your coach.

Protect your slide-out extension tubes from bending, causing difficult slide-out operation. Stabilizer jacks support 6,000 lbs. each and adjust from 20" - 34" H. The 5" dia. circular bases are stable on any surface and resist sink-in. U-shaped tops fit most slide-out frames. All parts are powder coated or zinc plated for corrosion resistance. Set of 2.

Technical Specifications

10.5 lbs.
U-shaped tops are 3 1/4" W x 2 1/2" D

Great idea for camping over an extended period with slide outs being extended for long periods of time.

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

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.

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?
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.
