Shutter Clearance Charts
|
Depth Clearance is the minimum window opening depth required for shutters to operate without interference.
Measure the depth of your window opening and then examine the drawings below to determine if an inside mount is
possible or an outside mount is required. Click on the link below to learn more about mounting frame
types.

Mounting Frames
Note: Add 1/2" to clearances below if using the Clearview Option for tilt control. |
Inside Mount With Z Frame OR Trim and Deluxe Trim Frames
Depth Clearance: 1-1/4” for 2-1/2” Louver, 1-3/4” for
3-1/2” Louver, 2-1/4 for 4-1/2" Louver.
These are the most common frames used with drywall openings
(windows with no wall trim) and openings can be somewhat out of square as the overlaping trim
piece will cover any gaps.

 |
Inside Mount Without Frame
Depth Clearance: 2” for 2-1/2” Louver, 2-1/2” for 3-1/2” Louver, 3" for 4-1/2" Louver.
Requires very straight and square window openings. Usually used with windows that
have existing wall trim. |
 |
Note: With optional 1-1/4” extended leaf hinge, the
clearance can be reduced to 1-3/8” for 2-1/2” louvers, 1-7/8” for 3-1/2” louvers, 2-3/8" for 4-1/2" louvers.
Inside Mount With Mounting Strip and Bent-Leaf Hinge
Maximum depth clearance: 2” for 2-1/2” louver, 2-1/2” for 3-1/2” louver, 3" for 4-1/2" louver.
Depth clearance can be reduced by 1” if mounting strip is installed closer to inside
of opening. However, hinges will project into room up to 1”. Requires very
straight and square window openings. Usually used with windows that have
existing wall trim. Extended leaf hinges also available. |
 |
Recessed, Flush, or Extended Inside Mount with L-Frame
Depth clearance: 2” for 2-1/2” louver, 2-1/2” for 3-1/2” louver, 3" for 4-1/2" louver.
For recessed mount the depth clearance is measured from the front of the L-Frame.
The L-Frame is the only frame which can be used when a recessed mount is desired.
The recessed distance can vary as needed. It is also possible to allow the frame to
extend from the window opening up to 1-1/4" to install as an inside mount when clearance
is not adequate. |
|
Outside Mount- L-Frame –
Depth Clearance: 0” for 2-1/2” Louver, 1/2” for 3-1/2” Louver, 1" for 4-1/2" louver.
For mounting on face of wall or on top of existing trim. |

For more projection, add one or more 1/2" L-Frame extensions
(see below).
