Rok Hardware Ratchet Headrest Fitting for Beds, Desk Lids, Drafting Tables, and Drawing Boards, Steel

We bought these to install a painting easel in our son's project desk and they work great! It was a little tricky getting them set just right since the surface had to fit flush in the desk, but they were perfect.

Good price and seems to hold up well. Used it for an art table. Doesn't always catch on the last notch or the first, but other than that it works fine. All the notches in between seem to catch fine.

I have a small table 2 feet by 1and ½ feet This devise works great to raise the flat top desktop any angle from zero flat to an angle around 75 degrees. I usually us it at around 45 degrees. All I have to do is lift it to 45 degrees an it locks there. To lower it to the flat position, I just raise it to around 85 degrees and then I can lower it back to 0 degrees (flat). Great product.

I’m strong (and awesome) like these hinges

Overall, a good product. There is a plastic keeper that holds the sliding metal parts together and allows them to engage to hold the desk top up, and to disengage when you want to lower it. To disengage, you simply raise the top past a certain limit and the plastic keeper then is supposed to allow the metal parts to slide past one another and allow it to come down. This disengagement action did not work on the unit that I received. After fiddling with it for a while, I saw that the plastic keeper fit rather loosely and that if I could make it fit tighter then it worked. I cut a thin shim and glued it in place along the bottom of the keeper, up tight against the metal part. Works great now. The keeper and the shim are actually nylon, a special kind of plastic that won't accept just any kind of glue. I used Loctite Plastic Bonder, a two-part system. Because of this, I can't give it five stars. On the other hand, there's nothing else quite like this thing for simplicity and strength. Hard to beat that. The geometry of your installation will determine how far the top will open and your desk top will incline. My table is about 22" deep, and the table top can incline about 30 degrees.

I installed this piece of hardware for a drafting table. I recommend it. I use one for a table 38"x30" and it works well. Sometimes the locking mechanism doesn't catch and requires some jossling but nothing unexpected. It's so much easier to draw while standing up with this piece. Awesome hack.

All the parts came except for the screws which wasn't a big deal . Works well but at times gets stuck. Will probably buy from this seller again if I need too

I used these hinges to make a desk for my 14 year old who loves to draw.I cut out a section to raise up and be used as an inclined drawing surface. It turned out perfect! I included pictures.These would make nice hinges for a coffee table with a storage compartment or a box with a prop-up lid.Note: these hinges alone won’t accomplish what I’m describing. You’ll need a set of traditional cabinet hinges as well. These just provide the height adjustment.
