Mesh A is a polyester mesh with opening sizes of 1/16 inch with 80 psi burst. This mesh can be used with birds, primates, mammals, small marsupials and aquatic creatures. The advantages of this mesh are that it is light and will not cause damage to delicate animals. It is used to prevent feather and digit injuries. It has narrow holes that do not allow small delicate digits to become entangled. However this is a delicate mesh and can be torn with sharp beaks or claws.
Mesh B is a polyester mesh with opening sizes of 1/4 inch with 120 psi burst. This mesh can be used with aquatic birds, felines, canines, small marsupials and fish. The advantages of this mesh are wider holes to allow sediment and small debris to pass and delicate enough to use on medium size birds without injury. However the hole size can allow small digits to become entangled.
