Measuring Egg Crate Grilles

Measure to determine your Opening Size: A = Top to Bottom (Opening Width) and B = Left to Right (Opening Length). Watch our "How To Measure a Bar Grille" video above to get more specific instructions. 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. Determine OPENING SIZE = Measure the INSIDE of your opening (A) = Width and (B) = Length
2. Determine CLEARANCE ALLOWANCE needed (0.125" recommended per side)
3. Determine GRILLE SIZE = Opening Size minus Clearance Allowance
4. Determine FRAME HEIGHT/DEPTH needed ("industry standard" Egg Crate Grille Frames are 0.75" height/depth, however custom sizing is available)
5. Choose Bar and Frame Style (eg. EC300 B Frame)
6. Choose Material and Finish - determine need for Screw Holes*, Tabs, etc
7. 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.
