BIG RED Screw Jack, 5 Ton (10,000 LBs) Expert-Level Car Support Screw Jack Applicable to House Construction and Bridge Stabilization, Black

I use it to unstick double hung windows. My 20+ year old windows are sometimes hard to latch because the upper window has dropped down slightly. And because that part of the window seldom moves they are sometimes break free. Lifting by hand requires a lot of strength, using a hammer is awkward and and even using a wood block between the window frame and the hammer you risk damaging the window. I found the small hydraulic jack a great way to lift the upper window frame tight against the top, so the window could be latched closed.

Great item, lifted my boat with no issues

Use this on my 2021 Rav4. I trust this more than the OEM jack.

I don’t know if it would take everyday use, but for a home mechanic, it works really well.

A brute great

I bought this to raise ceiling joists 1/4" to reinforce them. Nothing fancy. I simply cannot get this to extend under load. ANY LOAD. Before you say to yourself, "This guy just doesn't understand jacks", I will say that I do know what I am doing.I have a bottle of Johnson jack oil (USA) ready to go. I bled the unit first off, checked the level and found it well below the normal mark (according to the insert). I busts out my oil and topped it off. I bled the unit 2x and it extend up just fine. Buttoned it all up and started to work.The jack simply wouldn't extend with the 4x4 on it. So I put it back on the workbench and proceeded to bleed it again and again and again...10x at least. No help. It wouldn't extend with me simply applying downward force with my hand.The reason I bought this was a quick delivery for a simple job. Now I restore vintage jacks (auto and bottle) along with toolboxes, adjustable wrenches, vices etc. For fun and a little profit. Made in the USA.I had sold all my finished bottle jacks and didn't have the time to get into another rebuild before I needed the jack, so I bought the Big Red. Big mistake.Sitting on my shelf were 2 bottle jacks. A Walker from the 40's and Hein-Werner from the 30's. After I found out this Big Red jack was bad I just bought seals for the Hein-Werner and did a simple rebuild without the cosmetics (polish the guts etc). Took me 2 hours to complete and it was working just fine.This is what I should have done in the first place. There a few things I just don't trust made in China. Hydraulics and electrics. I should have known better, but I only needed it for one simple job...I highly recommend you buy a used, rebuilt USA made bottle jack. Walker, Hein-Werner, Blackhawk, Lincoln or even English Dunlap jack. Or even better, learn how to rebuild one. Lots of good videos out there.

Arrived missing oil so max height was only 15" instead of 17 5/8".Buy replacement oil at the same time if you need to use this tool right away.

Bought to use for a trailer to remove wheels. Works as designed and seems safe
