24V 4 Inch Linear Actuator with Instantaneous Switch,1000N Heavy Duty Linear Actuator Waterproof Speed 10mm /s with Mounting Bracket for Robot Snowplow Door Opener (100mm)

For my door closer it was great. I think it could have torn the house from the door. Certainly a fair price.

Wires were slightly short for my installation but easily added length. Used this product for the grass flap on my mower deck.

My only real complaint about this unit is the noise it makes when put under a load. Typical loud screeching sound you hear from these devices but this one was quite a bit louder than I'm used to.

Not nearly as strong as advertised

worked great, being able to stop and hold in any position at the push of a button. used it to raise a truck bed, a little weak to get the operation started though probably my angles...all in all I really liked it

This is a pretty good deal on this 12v actuator. It is exactly the size stated in the listing and seems to be the strength claimed as well. I like that it comes with a button you can use and mounting hardware. Installation for my project was easy, I didn't need the button as I am controlling it with an arduino. It works well for my purpose.

This is a really powerful actuator. I ordered this to lift the mattress platform in my RV to make accessing the storage area beneath easier. This really works well. It comes with all of the hardware needed including a up & down toggle switch so the installation was very easy. It requires a 24 VDC power supply. I am currently using two 12 V batteries in series until I can find a different power supply. I wish every RV came equipped with this! It really saves my back!

It's glossy black with a nice finish. It seems faster and quieter than the last one I owned. The included directional button works great too. In my testing, it only pulled 300 mA from my 24-volt power supply. Granted, I didn't have it connected to a door so the current draw may increase when pushing or pulling a load, but still, it's pretty good.
