The 18P3321 is a 33 x 21 in white-finished steel inner panel for 36 x 24 in enclosures, part of Hammond's 18P Series of inner panels for 1418, 1447, PJW and PHW wallmount enclosures. It gives panel builders, electrical contractors and OEM engineers a dedicated surface for mounting components inside the enclosure.
