Measuring Egg Crate Grilles

Measure to determine your Opening Size: A = Top to Bottom (Width) and B = Left to Right (Length). Our fabrication specialists can assist you in determining the perfect fit for your project.

Measurements should match the width and length of your opening’s “INSIDE space”. It is recommended to allow for clearance.  NOTE: Grilles are manufactured to the size given, and WILL NOT be automatically undersized.

  1. Measure the INSIDE of your opening: (A) = Width and (B) = Length
  2. Determine clearance needed and subtract from Width and Length
  3. Determine Frame Height/Depth required - standard Egg Crate Grille Frames are .75" height/depth, custom sizing is available
  4. Choose Bar and Frame Style (eg. EC300 B Frame)
  5. Choose Material and Finish - determine need for Screw Holes*, Tabs, etc
  6. Choose Method of Fastening - mountings for Egg Crate Grilles are similar to Bar Grilles, please refer to Methods of Fastening for Bar Grilles for recommendations

NOTE: Screw Holes are only provided if requesting Bar Grille mountings #514 or #515. Holes are placed .375” off edge to hole center UNLESS specified. Notify your estimator of specific screw hole layout requirements.
