Retrofitting with 20 yr. old Blum Inserta3/5
I have a kitchen I built about 20 years ago with painted MDF doors with Inserta hinges. Mostly due to wheelchair collisions, I am replacing all the doors and drawer fronts. The hinges still work fine, but a few need replacing due to corrosion from cleaning supplies. Would anybody know if the current Inserta Clip tops are interchangeable with matching existing hole patterns and 0 mm mounting plates? Same set back, same throw, same reveals?
I wish Dennis Bean was a Blum guy. He'd know. (Thank you Dennis for all your non biased technical help and information the last few years.)
Also, I tested one of the old hinges on a new bored sample and found that It could pull out because my current drill press has a very slight wobble making the cup bore at 35.5 mm. Is the tolerance really that tight on the Insertas? Half a millimeter causes failure to hold?
The old hinges are marked 74 559 01-02, but is the same on straight arm and cranked, so some info is missing.
Hopefully some old fart can help out this old fart.
There are basically 2 types of inserta hinges. The old style like you used, and the new ones with the integrated soft close. Both will work with your hole pattern.
The ones with the integrated soft close will probably work better for your application because the cam mechanism works in the two 8mm dowel holes, not the 35mm hinge cup hole like the old style. The 8mm holes do need to be as deep as the 35mm holes or they won't bottom out.
Also, the new soft close inserta hinges have to be pressed or hammered in. Not sure why Blum did that, it kind of negates the convenience of an easily removable hinge.
As far as I know the inserta hinges just push in by hand and then you flip the lever.
As far as the hole pattern....... IDK.
