You're on your own with these - figuring out where to place them on your doors. They break easily so I recommend ordering an extra pair (very cheap). But the lack of a precise way to locate the hinges adds complexity for the DIYer.

Using these on the canopy of a 310-gallon fish tank and they work perfectly. Soft close and lift assist work wonderfully.

Ordering was easy and help when needed was outstanding. They use USPS which isn’t good. They are in Florida and I am in Georgia. The hinges went from pompano Beach to Rhode Island then to Massachusetts then back to Georgia. A long route.

The support desk was super fast in responding to my detailed led lighting question. They got me the right info and looped in the manufacturer to assist, as well. Great job!

Had a 2ft x 14ft Honduras mahogoney custom desktop and needed middle support. These legs were strong solid adjustable and gave a great accent.

My swing cabinet hinge broke and this item fit perfect. Great experience
