Congratulations on your new SHrEDder!
Stainless hardware is provided – Two #1 Phillips screws per SHrEDder are simply to be screwed into the side of your enclosure. SHrEDders are designed to be placed anywhere within the enclosure you feel is best. Since snakes will often start the shedding process using perch mount corners, a popular spot is in between perch mounts with the “teeth” facing down and top/bottom flat spots parallel with the roof and floor.
