Box Cover Considerations

The size of the box cover depends on two things.

1. The height of the rails - A taller shutter will require a larger box cover to contain the greater number of slat required.
2. The type and size of the slat - The different sizes and types of slat available require varying amounts of room to roll up. A smaller slat will require a smaller box cover.

   EXAMPLE: A shutter With 84" Rails

   Slat & Size	Side Rail Width
   32mm PVC Slat requires a 7" box for this height	2 1/8"
   40mm Roll-Formed Aluminum Slat requires a 8" box for this height	2 1/8"
   52mm PVC slat requires a 10" square or 10.25" taper box cover	1 3/4" V-System or 2 5/16" or 3" maxi
   55mm Roll-Formed Aluminum Slat requires a 10" square box cover	1 3/4" V-System or 2 5/16" or 3" maxi

   (see Technical Information for complete chart)

There are two styles of end caps and how they relate to the rail.

Cast-aluminum end caps fit flush with the rail on VM and Maxi System.
V-System with 1.75" rails have a 1.125" overhand to the side of the rail.

More details are located in the architectural brochures.
