Paddle & Spectacle Blind Dimensions Chart

Isolation thickness for all line sizes is 5/16".

The Paddle Blind & Spectacle Blind Thickness Dimensions Chart is a critical reference for the required thickness of isolation blinds by pipe size and pressure rating. Adhering to standards like ASME B16.48, it ensures a blind can safely withstand full differential pressure during maintenance and line isolation without bending or failing.

Engineers and safety managers rely on these measurements to select the correct, code-compliant blind for secure, leak-free positive isolation.
