Curved Headrail Bend Radius Chart
Headrail cannot be bent to a radius tighter than 80" (203.2 cm).
To check your application for bend radius:
1. Determine preferred application—A, B, or C (below).
2. Measure (B) and (X) for your application (diagrams below).
3.
On the Bend Radius Chart, draw a line up from your (B) dimension
and over from your (X) dimension.
4.
If your two lines intersect below the 80" (203.2 cm) radius line,
application is okay.
If lines intersect above the 80" (203.2 cm) radius line, application
is not feasible.
5.
Factory will make allowance for vane clearance.
NOTE:
Depending on bend, separate tracks may be recommended
by factory.
Factory will make allowance for vane clearance.
Measurements should be taken from wall to wall or window to window.
Standard Application (A)
Measure exact window baseline (B) and depth (X). Factory will make
deduction for vane clearance. Diagram shows back corner of track sitting
on the baseline.
This minimizes light gaps at ends of tracks.
Optional Application (B)
Measure exact window baseline (B) and depth (X). Indicate that front
corners of headrail should be flush with baseline. Factory will make
appropriate deductions. Diagram shows front corners of track sitting on
the baseline.
This application could leave light gaps at end of track
giving visibility to outside.
Optional Application (C)
Measure exact window baseline (B) and depth (X). Also indicate recessed
wall measurement. Factory will take deductions for vane clearance.
Diagram shows track extending beyond the baseline.
This will help cover
the side walls to minimize any light gap.
See appropriate window drawing. To ensure a proper fit, fax a diagram to customer service.
