About this file
This is a technical drawing document showing specifications for fish screen mesh panel components and associated link bars. The document contains detailed engineering drawings for three main parts: Part 146-1 (Link Bar, M-145 Item No. 4), Part 146-2 (Lap Link Bar, M-145 Item No. 3), and Part 146-3 (Mesh Panel, M-145). The drawings specify precise dimensional requirements, including tube specifications (TS 1 X 3 X .120), hole placements on various centers, and straightness tolerances within 1/8 inch across the entire length. The mesh panel drawing shows dimensional specifications with tolerances of ±1/8 inch for certain measurements and ±0.125 inch for others, along with marked zones [A], [B], and [I] with specific tolerance bands of +0.125/-0.125 inches.
The document explicitly states that these drawings are not part of the solicitation itself and directs users to reference separate detailed drawings of the fish screen mesh panel. The drawings are provided at various scales (12"=1'-0" for certain components) and include symmetrical design specifications except where noted. Material specifications are referenced but deferred to separate specification documents. These technical drawings would serve as reference documentation for manufacturers or contractors tasked with fabricating or assembling the fish screen mesh panel components to precise engineering standards.
