Review: Got the lighter, 350 lb capacity hinges, secret storage - sturdy parts - Drawing up plans for a secret storage area for power tools, computer equipment. Had a break in at the farm where thieves stole a lot of stuff. Thinking to put a recessed bookcase/hidden door (paper backs and cookbooks!) with storage area behind. Found these. After looking the parts over: seem very sturdy. Fit and finish look good, no obvious issues. All the parts were there, as well as the instruction sheet. It's a complete set. I was concerned enough with the weight of the books on the shelves - I weighed the books. If I don't overload the shelves, it will be well under 300 lbs. Now husband has to build the custom sized recessed bookcase/door. We'll make the shelf depth slightly smaller than normal bookcases. Will update once the project is done. Review: Sturdy and effective but challenging to install - This hidden hinge is very sturdy and will support a heavy weight like a door or bookcase but it was a little challenging to install. Part of the top hinge needs to raise and lower into the header beam which meant drilling a spot for it to move. It wasn't a problem it just a bit to figure out. ## Features - The pivot hinge for DIY, secret door, hidden door, bookshelf door, cabinet door, panel door, wine cabinet door, closet door, you can design and create the unexpected door opening in the movie by yourself with this set of hinges. - This set of pivot hinges is mounted on the top and bottom hinges of the door and frame to open the door by rotating it on its axis, The weight of the door is carried by the heavy-duty pivot bearing at the bottom and the floor, with a maximum load of 330 lbs. - Made of stainless steel and cast steel, the bottom bearing rotates smoothly and is durable and load-bearing, so it can easily and stably support heavy and wide doors and put all kinds of book on the "door". - Installation note, need to be installed by professionals, and design the door and door frame in advance, pay attention to the gap between the door and the door frame for rotation will not be stuck.
