🛠️ Step-by-Step Breakdown:
Step 1: Measure the Outside Curb Dimensions
📐 Use a tape measure to record the long (X1) and short (Y1) dimensions from the top of the curb flange. Don’t add to the numbers—MicroMetl engineers do that.

Step 2: Document Site Obstructions
📸 Note walls, gas lines, or electrical conduits surrounding the curb. Include distance and orientation clearly on the worksheet.

Step 3: Access and Measure Return & Supply Openings
🔧 Remove the economizer panel, OA hood, and filters. Use a level to create a plane, and subtract flange depth for an accurate measurement of return and supply air openings.

Accurate curb adapter measurement is critical when replacing an RTU without a model number. With the MicroMetl worksheet and this method, you’ll reduce errors and ensure precise custom fabrication.
