Hammond Manufacturing 1455F Extruded Aluminum Enclosures feature integrated slotted flanges for easy wall mounting. These enclosures are designed to house P.C. boards or for equipment interfacing. These P.C. boards mount into extrusions by sliding into internal slots extruded into the enclosure body. The Hammond Manufacturing 1455F enclosures feature a rugged body construction from extruded aluminum with a minimum thickness of 1.5mm. The slotted flanges provide a completely flat bottom surface and transition seamlessly into the extrusion body for a finished look.
