JUST STEP ON IT FOR INSTANT RELEASE: Sturdy spring mechanism for easy release- No bending down, No manual lifting, No dirty shoes! INNOVATIVE DESIGN: In the state that door stopper is fixed on the floor, You just step it. Then it ascends. MULTIPLE FLOORS APPLICABLE: door stopper will prevent your door from moving, reduce the noise while closing door. Whether it is tile, vinyl, carpet, glass, concrete or wooden floor. RUGGEDNESS: Doorstop made of flexible, soft, anti-slip rubber tip and high-quality zinc alloy material.Kickdown door stop is designed for heavier doors, with 0.23 inch knob and high-quality mental material. Tips: The kick door stopper is not hold in a hollow door You Can Get: 3 X Door Stoppers 12 X Screws Review: The design works well to engage and disengage the kickdown lever. Construction is generally good but there are potential point of corrosion in that there are parts make of ferrous metal, especially the spring that is the heart of the mechanism. I disassemble the doorstops and put grease on the spring and whatever parts I could reach. Since I'll be using these on outdoor gates, it will help keep them from rusting out but I expect they will have a finite life. Otherwise, for the price they are good. Review: Now, getting installed was a little tricky for me but I was able to do it! They are able to hold the doors just fine! We have a garage door I wanted held open for when we bring in groceries. But if any windows are open or doors anywhere else on main floor the door slams shut with a lot of force, having this installed has prevented that from happening. It was totally needed to pre drill through the metal door but I went on the small side so the screw would catch and stay and I used lock tight. Then I put one on my bedroom door, I have french doors and when the one is open it will always half close, I pre drilled the wood and this was easy to put on and it works totally well! I used these only for holding doors open, and not for keep a door from opening in case someone tried pushing in my door. So there is that. What I love about these after they were installed is that I use my foot to kick it down into place and then I just step on the lever that went with it and it pops back up! I don't have to get under it and try to prop it up, just push down and it goes! really easy to use when installed! My rating 5 star - I really like this item, really made me go wow you should get this 4 star- I like this item and it is fine, but didn't go wow you need this 3 star- this item is alright but has a few flaws 2 star- quiet a few flaws I would totally go somewhere else 1 star- junk no good don't waste your time. ## Features - MOST CONVENIENT: 3 Pack door stopper is more convenient and flexible than the traditional door stop.In the state that door stopper is fixed on the floor, You just step it.

Otherwise, in public or commercial setting they will fail, break, etc., so I no longer recommend this product. If you choose to buy and install, please follow the directions provided. In our case we had other door stops previously and put these at the same height. Open it and see how far off the ground the surface is where you put the screws. **Q: Rubber worn down, can't find a replacement. Can anyone help? This item will be worthless if tip Can't be replace** A: You are fortunate that you got to use yours long enough for the rubber to wear down. The metal parts of ours broke, spring popped out, etc., making ours useless within the first 60 days in a church setting and a senior center setting. I don't know where to get new rubber tips, but would not buy this product again for our needs. People just don't understand how to work them without stepping too hard on the lever and breaking it off. The key is to push door back a bit to relieve pressure on these and THEN step gently on lever to make door stop come back up. We couldn't reach all who used these doors in a public place, to give them "Orientation and instruction" so ours are useless. **Q: Is this gate strong in magnetic force? Can we close the door for children and pets?** A: The magnetic force is very strong. I have to work hard to close the door. My child can't close the door, so I don't worry about the child crushing his fingers when he accidentally closes the door **Q: Does this door stopper work? Can it keep the door open?** A: Purchased a few just to confirm they would Work on our commercial office doors, well these stoppers work great and easy to install, I need to purchase a dozen more. Good Product would recommend ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***K on 10 January 2022* The design works well to engage and disengage the kickdown lever.
