CONCEALED
Concealed hinges are not visible when the cabinet door is closed.
They can be European style cup hinges (Amerock, Blum) or knife hinges
(Amerock, Youngdale); although knife hinges do leave a visible slot
on the edge of the door.
DEMOUNTABLE
Demountable hinges come in single and double varieties. The single
demountables, demount from the cabinet door only (this
requires a special slot be cut into the door for new installations) and
screw directly to the edge of the face frame. The double
demountables demount from both the door and the frame (and both require
machining for new installations).
FREE-SWINGING
Free-swinging hinges do not employ any closing mechanism, meaning the
door doesn't shut by itself. This feature has nothing to do
with whether the hinges are concealed or non-concealed, overlay
or inset.
INSET
Inset means that the cabinet door is actually recessed into the
cabinet opening. If it is partially inset, the recess distance must
be measured accurately to determine size needed (3/8" inset is a common
partial inset hinge). To determine this dimension, measure the inside
step of the recess cut (the part of the door that would extend into the
cabinet opening when the door is closed). If the front of your cabinet
door is flush
with the outside of the cabinet face frame when the door is closed
(meaning you can see a crack all the way around the cabinet door between
the door and the frame), you have a full inset hinge.
KNIFE
Knife hinges are a variety of concealed hinges that require a slot or
saw cut into the door to house the "knife" (some types that mount on the
top or bottom of the door don't require these cuts). The hinge mounts
to the back of the door and to the edge of the face frame.
MOUNTING PLATE
This is the piece that mounts to the cabinet, either the face frame or
the inside of the cabinet for frameless cabinets. These are generally
used with concealed hinges.
OVERLAY
Overlay is the distance that your cabinet door extends past the actual
cabinet opening on the hinge side. To measure this, with the door
closed, make a mark on the cabinet frame along the edge of the door (on
the hinge side). Open the door and measure from the mark you made
to the edge of the face frame (the cabinet opening) and that is your
overlay.
SELF-CLOSING
Unlike the free-swinging hinges, self-closing hinges do just what the
name implies, they close by themselves if the door is within a certain
distance from the closed position. This feature has nothing to do
with whether the hinges are concealed or non-concealed, overlay
or inset.
SEMI-CONCEALED
Semi-concealed hinges are partially visible when the cabinet door is
closed. The hinge pin is what is visible and on some styles, the
screws that mount the hinge to the cabinet frame are visible as well.
If they are not visible, then the style is wrap, meaning it wraps
around the frame and screws to the edge of the frame.
WRAP
A wrap hinge simply wraps around the cabinet frame from the front to the
edge and sometimes partially around the back of the frame. Like the
closing styles, this feature has nothing to do
with whether the hinges are concealed or non-concealed, overlay
or inset.
