Arch Wall Niche

The Flat Arch from Fast Arch of AmericaAn Arch Wall Niche is essentially the same as an arch, except the back side comes down as a flange, instead of going up. The flange goes flush with the flat back of the wall niche.

Your Arch Wall Niche can have any arch curve profile you like.  They come in Flat ArchEllipse Arch and Half-Round Arch profiles.  Our Arch Wall Niche has a flat back.  If you would prefer a rounded back, please check our Dome Wall Niches.

Fast Arch of America makes creating a wall niche a simple process.  It starts with just 3 simple measurements.  There's no computation involved - we handle all of that for you.

When you get your niche kit, you'll find two halves to the niche.  Just 12 nails later and you're done.  After you've put in one or two, it'll be easy to put them up in under 2 minutes each.

Of course, at Fast Arch of America we're always ready to do something a little unusual.  Need a really big niche?  Our motto is "Any, Size, Any Shape, Any Time."  Give us a a chance to prove it.



How to Measure and Order a Fast Arch Niche

How to Measure for a Fast Arch

Measure the actual width of the opening from side to side (as you look through it) of the rough frame opening.

"Flat" and "Ellipse" are usually patterned in 2" increments to allow for adjustment during installation.  This won't affect the appearance of the final product and makes installation much simpler.  In other words, 36-3/4" opening would take a 36" Flat or Ellipse Arch.

Half-Round Arches require a closer tolerance and should be measured to within 1".


This is the measurement between the top or peak of the arch and the lowest portion of the arch.  Other terms you may have heard are the rise, leg, spring, or slope of the arch.

A good rule of thumb for an unspecified drop is to use a 6:1 ratio to the Width.  In this case, a 48" wide arch would have a drop of 8".

The drop of a half-round or half-circle arch should be 1/2 of diameter of the circle,  In other words, the drop of a half-round arch with a width of 72" would be 36"


The measurement of the thickness of the opening or niche (as you look through it).  Usually it's the depth of the framing member. The measurement should be accurate to 1/4".


Will this be an Arch or a Niche.  Arches are passage type openings and Niches have a closed back.  The difference is in the direction of the back flange and the cost is the same.

Installing a Arch Wall Niche

How to Install an Eclipse Arch









The Niche Code is written on the throat of each niche and it will tell you the size of the niche.  For example, an Niche Code of 42/8 is meant to fit a 42 inch wide opening and create an niche with an 8" drop.

Installing a Fast Arch Arch Wall Niche is quick and easy:

  1. Get the Drop measurement from the Niche Code.  It's the second number in the code.  Measure down from the bottom of the upper framing member the distance of the Drop plus 1/2 inch.  Draw a squared line across the inside face of the vertical framing member.
  2. Repeat on the opposite side framing member.
  3. Slip the half-niche over the framing members and align the 1/2" tail with the squared line.  Make sure the arch is snugged firmly to the framing members at both the peak and tail.
  4. Insert a screw or drive a nail through the nailing flange near the bottom (indicated as Nail #1 in the illustration).
  5. Again making sure that the half-niche is snug to the horizontal framing member, place a screw or nail through the top nailing flange near the peak (indicated as Nail #2).
  6. Place a third nail or screw at the outermost corner (indicated as Nail #3).
  7. Move to the backside of the opening and repeat the procedure with 3 more fasteners.
  8. Slip the second half-arch over the framing members, aligning the tail with the squared line.
  9. Drive nails or screws at points 4, 5 & 6 (as indicated by the illustration above)

Important Notes:

  • There may be an overlap or gap of up to 1" between the two half-arches. The final appearance of the arch will not be affected.
  • For even easier installation on wood framing, Fast Arch has designed a double-faced magnetic hammer.  A 3/4" roofing nail can be driven through the nailing flange and into the wood with a single stroke.  This tool allows even very large niches to be installed by a single person and speeds installation time.  For more information on this tool and its availability, please call us.
