EABL and CACH will use the same size box with the same size entry hole. I offer them boxes with the same specs and then use a reducer if necessary.
Renee is right about the EABL entering and destroying eggs. Seen that. If the hole is already smaller (is it 1.25″?) the blue shoulders won’t fit.
CACH don’t need sawdust in the bottom of a box. They are going to carry in tons of green moss as a base and then line the cup with even softer materials.
Ospreys! Lucky you!
