RAI - Radiused Angle with Inside Length

Here's another problem solver from Fast Arch:  A simple way to create a Light Cove for a Dome.

We make a lot of domes here at Fast Arch of America.  A lot of domes have a chandelier or other light fixture hung in the oculus (top center).  Another way to show off the drama of a dome is with a light ring.  You just create a tray around the outside edge of the dome and put a rope light of some other indirect light source that shines up into the dome.

Before we came up with the RAI, that tray was a hassle.  It took a lot of playing around with to put up.  So we made an easy way to get the job done fast.  If you're looking at creating a dome, you definitely want to think aobut adding a Radiused Angle with an Inside Leg to our order.

How to Measure and Order a Radiused Wall Track: RAI

RADIUS:

The Fast Arch Radiused Angle with Inside Leg can be built to any radius you need.  Literally.  The RAI is based on the radius to the inside leg.

WEB WIDTH:

This will affect your lighting options.  How big will your tray need to be?  We normally build the RAI to a width between 2-1/2" all the way to 12".

LEG HEIGHT:

The measurement of the height of the side flange.  For the RAI, we normally make the leg 1-1/4".

LENGTH:

How long will your curve be?  That is the length.  Our RAI products are available in segment lengths of up to 144".  If you're doing a whole dome, we'll send it in several segments to make it cheaper to ship and easier to install.

GAUGE:

We'll use the gauge you desire, from 25 to 14 gauge sheet metal.
