what can i say but that with Soss, you get what is paid for! if you're not a professional crafter, these aren't for those DYI people, experience in precision router works and knowing how to make a template guide for each custom made piece you might use these in, as well as proper size for weight and door thickness, they are everything else but easy to install! know what your doing, or waste a "lot" of money learning!!! they're a professional crafter precision hinge for concealed doors!happy crafting!signed as a; 49 years experienced custom furniture producer..

went to Soss's webpage to use their calculator to determine the correct and appropriate hidden hinge. after installing, i noticed that both hinges are starting to deform/bend! went back to their website to check If I accidentally ordered the wrong but the part number was correct. This product is just complete junk.,...maybe for jewelry boxes! also disapointed that these are cheaply made in asia! not the Soss made in USA that I previously thought!

Hands down the best hidden hinge on the market.I've installed hundreds of them. That's not an exaggeration. Buy the router template. Makes life much easier.

These hinges are great. I ended up buying the Woodhaven 8661 for Soss 101 Hinge jig. It is pricey but makes installation pretty easy (It could really use a center mark or some other kind of indexing but otherwise its great).These hinges don't really need any more reviews. They have a great history and their quality is very high. I'll use them again whenever they are appropriate.

Used this for a hinged desk lid, the previous hinges were made in china and lasted for years, installed these and one broke within the first month
