Lift up Top Modern Coffee Table Desk Mechanism Hardware Fitting Convertible Furniture Hinge Spring Stand Rack Bracket 240mm/9.45 Inch (Air-Operated)

I bought this homemade chest for a song and felt it was perfect for a lift-top. As others mentioned, no screws or instructions, but brainstormed with a few friends and installed fairly easily without any help.Do not cut tie straps until you’re ready to install the lid. Do not remove current trunk hinges so you can open and close lid for accurate measurements.I installed sides first with just 3 screws (on each side), making sure top bracket was level with trunk top. Then using a t-square (with lid open), drew a line from the center hole of the top mount to the outside of trunk. I measured repeatedly for center hole for lid mount. And even measured the distance between the two center holes on each side. Be sure to account for overhang, mine is 1/4 inch. Then I marked inside of lid top for center hole and measured again.I removed old hinges and laid the lid bottom-up on the floor and drilled pilot just for the center hole, To easily find hole later, I marked with pink duct tape.Thenn I cut the tie straps, raised the lift-top hinges and placed lid on top of the hinges. I had to lie under lid to attach lid to just the center hole on each side. This was the only hard thing about this process.Carefully Lowered lid to make sure it was seated correctly. Then raised the lid and marked all lid holes with a white sharpie.I totally removed the lid (took screws out of center holes), flipped it over and drilled pilot holes for everything. Then I put it back on the hinges and screwed in everything.It lined up perfectly. I secured each side and all holes on top. I bought a multipack of carpentry screws for the various sizes for about $6.You have to use both hands to raise and lower racking is minimal, but very stable once it’s up.For less than $200, I have a beautiful and functional lift-top coffee table (toy box) for the grandbabies.Hope this helps. If I can do it, you can too.

Purchased these to make a small ottoman into a short side table desk for an RV. These arms worked very well for what we needed. These don't lift the table too high so make sure to measure before you purchase to know what you are getting. We went with the springs over hydrologic lifts so they'd be less likely to have mechanical or twisting issues. Good price for what you get. When installing you need to have basic tool/handy skills and tools. It took some measuring to build the base exact and drill holes into the side supports. The springs do snap into place when opened so if your base isn't too heavy you have to hold the base when opening. I haven't weighed how much the tabletop holds but it's very sturdy.

This is exactly what I need to build a lift top coffee table. The gas hydraulic mechanism is sturdy but smooth. I also wanted two separate devices so I didn't have to alter my build plans to accommodate the style where the hinges are connected by a cross bar. It stays open when it's open and stays closed when it's closed. The price is right for a quality product.It does not come with installation instructions, but it is easy enough to figure out. I used 1.5 inch #8 size screws (for those who don't know, #8 refers to the diameter of the screw, that's what size the holes in the hinge are. The only issue is that the mechanism is in the way and blocks the screw holes. I ended up not using each hole (seemed pretty sturdy even minus a couple screws) since I wasn't able to get in there with the drill. My husband suggested loosening the nut that holds the hydraulic mechanism in place to unblock the holes. I did not want to mess with it but it's an option.

It’s still new but seems like it should work well and last a little longer than most.

After searching for an inexpensive lift top coffee table for months, I decided to convert our existing Ikea Hemnes table with these brackets. I didn't read carefully that there are no instructions or hardware, but it wasn't a big deal. I used #10 screws, 3/4" in 7/8" thick wood. There's probably a sweet spot for how wide the table can be for one-handed opening and closing - mine is too wide for that. So it's a little awkward and you have to carefully move it, but it's not a big deal especially for the price.

As described. Lifts up 5.5 inches, comes forward 10 inches. There is racking, which can easily be avoided by using 2 hands on either side of the top and lifting evenly and carefully. Used on a white oak coffee table with a 38in x 24in top, and there are no issues with the top holding the springs down. Mechanism fit into 4.25in tall base and were installed before the bottom was placed into the base. It would have been extremely difficult to install without access through the bottom of the table. Seemed like a lot of screw holes so skipped some and still seems to work fine.

This holds well but doesn't open or close smoothly, more like a strong pull. Don't expect this to be as nice as on pre assembled furnitures of higher value. They are also a bit short but they serve their purpose.

Love these on my coffee table! To install, I flipped the whole thing over, marked the holes, pre-drilled, and screwed each side in. Simple as can be and has stood up to my 9 year old pushing it up and down multiple times a day. One thing is that it needs to be pulled with both hands so it doesn't twist but that's not the part's fault at all. That's what happens when they aren't hooked together and are mounted so far apart. If I wanted one hand operation, I would have sucked it up and bought the much more expensive set that is hooked together as one piece instead of two.

Exellent

Made a coffee table from butternut for my son for Christmas. He likes to eat dinner in front of the tv so I wanted something that would life the top to a tv tray height. This worked great. Since I designed the table around the lift it was not hard to install. Thanks Russ

Used on a lift top coffee table. Top is a 1.5 inch thick Maple top 42 inches X 18 inches.Lift top mechanism works perfectly.

Easy to install, not loud and easy to use after. Enough strength.

The hardware works extremely well. It would be nice to have some way to adjust the strength of the gas assist but that really isn't necessary, it would just be a bonus. Some people complained about the hardware racking to the side due to a lack of support crossbar, but I haven't experienced this at all. I would recommend these to anyone.
