Hinge FAQs

Q: I have to install some 35mm concealed hinges tonight(!), but I don't have a 32mm bit. What should I do?

A: In all likelihood you are using hinges that were designed for the 32mm system, but the hinge cup is typically 35mm. For 35mm you can use a 1 3/8" Forstner style bit in a pinch, but it will be a little snug. By the way, when you do buy a 35mm bit, make sure you get one that is also the right length. Many of these bits are stubby, for use in special hinge boring machines. If you are using a drill press you will likely want one with a longer shaft. The other option for a small shop is a special 35mm hinge-boring jig that is powered by your hand drill. This tool will help you to position your holes precisely, and really shines when you have to bore large doors that would otherwise be tough to handle on the drillpress. back to index

A: Our hinges are made to fit several common hole patterns and we will gladly do whatever research that is necessary to help you use our product. Ask your Häfele sales representative to explain our hinge program on their next visit. back to index

Q: How do I choose the right hinge, plate, screws and degree of opening for my project?

A: If the cabinet is in a corner, with its door opening into another cabinet, the swing should prevent the door from slamming into the door next to it. In that case, you'd choose a hinge with a 90-95 deg. swing. The larger the swing angle, the further the door will swing open.

Use the charts in "The Complete Häfele" catalog to help you decide which swing and style of hinge would be best suited for your project. Style, function and price are all factors in any hinge purchase, so look carefully at all three. If you decide that you want to use concealed hinges, use the catalog to help you choose the proper mounting plate and to calculate the "Tab" (the distance from the edge of the door to the edge of the 35-40mm hole for the hinge).
