Measuring Instructions

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 5 easy steps for getting the right grille:

  1. Measure the opening A x B.

  2. Determine clearance allowance needed (ex. 1/16” on each side).

  3. Calculate grille size: opening size minus clearance.

  4. Chose Grille Type and Frame Style. - e.g. - LG10 B frame.

  5. 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.

FLANGE-LESS GRILLES

Flange-less linear bar grilles, listed below, sit flush in the opening. In this case the opening can be 1/16” larger than the grille to allow a proper fit. The opening cut needs to be clean for an aesthetic look.

FLANGE-LESS GRILLES: Core Only, A and G frame.

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.

FLANGE GRILLES: B, C, D, E, F, J frames.
