Old GRASS Hinges, anybody have the drilling offset"

[Lisa Starr]

I have some old GRASS 850-01 Hinges that I'd like to use on some shop cabinets. They also have 99-12 stamped in the hinge cup. I normally don't use this brand, so I have no tech specs for the drilling offset and overlay. Can anyone enlighten me on this?

I think those are 1/2 overlay (3/8 inch). Should be a 35mm bore 20 - 22 mm from the door edge. I will check dads old stock and old supply catalogues. You could make a mock up with scraps. I think it is a face frame hinge.

I have an old KV that matches the web images of the 850-01. It is closer to a full overlay (9/16 inch) when bored at 20mm

[Lisa Starr]

Yep. It is definitely a face frame hinge. I figured I would end up making a mock up, but thought I'd see what others had to offer first.

I never used face frame hinges, but the frameless always said 3-5mm of material left from the edge of the hole to the edge of the stile.
