Slotted Screens

The best way to specify slotted screens is to specify “long slots parallel to 49” dimension” as in diagram #1. In instances where length and outside hook flange (OHF) are the same, it is necessary to specify the direction of long slots in relation to length.

Example

• Diagram #1: “long slots at right angles to length”
• Diagram #2: “long slots parallel to length”
