Measuring Instructions In Stock Grilles (B frame)
LINEAR BAR GRILLES
Measure your opening, start with A - top to bottom and continue with B - left to right. It is recommended that you leave 1/16” clearance on all 4 sides for a proper fit. Our grilles are manufactured exact size, we will not deduct anything from the size you provide us. For example if your opening is 5-1/8”x 36-1/8” you should buy a 5”x 36” grille. If you require an access door, please make note of the door location in the opening. Our fabrication specialists can assist you with more complex projects and we offer on-site measurement for projects in the Tri-State area.
Here are 4 easy steps for getting the right grille:
Measure the opening A x B.
Determine clearance allowance needed (ex. 1/16” on each side).
Calculate grille size: opening size minus clearance.
Chose material and finish and determine any special requests: mounting holes, doors, mounting tabs, etc.
Note: Screw Holes are only provided if requesting mountings #116 or #117.
Holes are placed .375” off edge to hole center UNLESS specified.
GRILLES WITH FLANGE
Linear Bar Grilles with flange will cover small gaps around the opening. A 1/16” clearance is recommended to ensure a proper fit. The flange will overlap the opening and can work as support for the grille.
