How to measure:
For flat grills:
- Measure the aperture EXACTLY.
- Hold the tape measure flat and straight.
- DO NOT allow a fitting allowance, let us do that.
For folded grills:
- Measure the depth of the channel with a steel rule.
- Measure the width of the channel with a steel rule or caliper.
- Measure both inside & outside channel apertures EXACTLY.
- Hold the tape measure flat and straight.
- DO NOT allow a fitting allowance, let us do that.
Note:
We WILL NOT refund improper fitting grilles if the clients supplied measurements are incorrect. 'Class 1' accuracy tape measures should be used, and used correctly.
