Features

  • GREATER STABILITY - The slide out supports save wear and tear on slide outs by reducing sag, can effectively solve the sagging and bending in the slide-out rails, and also help prevent costly slide out frame repairs. The support stands to help a little bit in the stability of the trailer. But please take note of the warning to "NOT" overtighten the support stands. This could cause damage to your slide out.
  • DURABLE - Heavy-duty steel and zinc powder-coating finish provide maximum strength and longevity for these rust-resisting RV slide out stabilizers. A new folding handle allows jacks in small compartments
  • ADJUSTABLE DESIGN - The stabilizer jacks support 5,000 lbs. each and adjust from 20.5" - 38.5" H. The 5" dia. circular bases are stable on any surface and resist sink-in. U-shaped tops fit most slide-out frames
  • EASY OPERATION - 2 per box, easy to operate, no assembly required. From the lowest setting, use the folding handle to raise the bracket slowly to meet the RV slide out supports bars. It is suggested to use concrete blocks or wooden leveling blocks for campers to stabilize the RV slide out jacks on an even surface.
  • WARRANTY - WEIZE aims for quality followed up with quality customer service directly provided by the manufacturer. The item is free from defects in materials and workmanship 1 year since purchase. Our support team is on standby for YOU.

  • Easy to use and sturdy
Well packaged so they survived careless shipping. Easy to use and operate smoothly. Bottom is slightly rough, so they work best on a pad or board. Top is perfectly wide enough for a standard 2x6 board, making it easy to add height or padding.

  • well built and simple to use
Size: 39 inch
like the ease of use and the large pad size on the top of the jack.

  • Works well on 6 year old slide out.
Other than being old very easy to set up and adjust. Hard part was getting under and back out.

  • good solid construction, top needs to be flat
Size: 39 inch
It is well constructed and and works smoothly. It would be perfect if the top plate had just one ear so it would cup the side of the slide and fit the bottom without a buffer board.

  • A Quality Product
These supports came very well packaged and arrived in a timely manner. They are high quality and adjust easily. The top plate fits a finished 6" beam perfectly. I was so satisfied, I ordered another pair for future projects.

  • Fantastic deck supports.
We had an issue with a main horizontal support beam under our porch. The original builder did not place a vertical support beam where the horizontal beam meets the house. I noticed the porch was sagging and when I checked it out, the main horizontal beam was separating from the under porch rafters. I was going to use wooden beams to support, but then I found these supports. They worked great, easily sizable , easy to install and I was able to crank these tight to support the beam. They are top notch. I ordered a second batch in case I need more. ... show more
