Abstract

A grid with calibrated openings is used to control the size of objects without damage. It may be used in a liquid. The grid is made up of transverse tubes (1) and vertical bars (2). The transverse tubes (1) are made of iron or any other material. The tubes (1) have holes (3) into which are fitted the vertical bars (2). The bars (2) are made of similar material to the tubes. The tubes (1) and bars (2) may be attached by rivetting, threaded joint, welding, clamping, adhesion or pinning. The cross-section of the tubes (1) and bars (2) may be circular or oval. The grid may be plane or curved, and is used esp. to separate different sized fish.
