Review: Working out great - My back yard is very uneven. I used these to level the platform under my shed (holds bikes, mower, tools, bags of soil and mulch). I added bike grease before installing which made them super easy to adjust for settling. No warping or corrosion after a year. ## Features - Compact yet Powerful:The Mini Screw Jack may be small in size, but its strength and durability are anything but small. - User-Friendly Adjustments:Easily adjust the height of the Mini Screw Jack with a simple pipe wrench.

I will order more shortly. ### ⭐⭐⭐⭐ Working out great *by T***7 on 26 January 2025* My back yard is very uneven. I used these to level the platform under my shed (holds bikes, mower, tools, bags of soil and mulch). I added bike grease before installing which made them super easy to adjust for settling. No warping or corrosion after a year. ### ⭐⭐⭐⭐⭐ Lots of uses for these *by J***H on 23 April 2024* My front porch is older and I have a couple younger dogs that run and jump off/on it. I've taken two of these and a 4x4 to add support. I also used a concrete block under the jacks. Works well. It's adjustable. Can be a temporary fix or long-term. ## Frequently Bought Together - RULLINE Adjustable Floor Support Jacks - Set of 4, Ideal for Floor Joists, RV Steps Stabilizer,Mini Screw Jack (3.5" to 6" Extension) - YEUQWJ 2 Pack Adjustable Support Jack for The Floor,Post Floor Joist Jacks,Deck Foundation,RV Step Stabilizer,Mini Screw Jack- Post 4" to 7" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/666183519-rulline-adjustable-floor-support-jacks-set-of-4-ideal-floor](https://www.desertcart.kg/products/666183519-rulline-adjustable-floor-support-jacks-set-of-4-ideal-floor) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-14*
