A newly repaired screen about to leave the shop and inserted into a raceway. Each screen is 3'x8' with 2" angle framing, slotted aluminum screen, 1 aluminum strap, and a combination of rivet and screw fasteners. Optionally some screens may have rubber, foam or oakum used to seal gaps between the metal and cement that might allow passage of small fish.
