comPosite Panels for Junction Boxes and ul/nema Wall-mount enclosures
Manufactured from light-brown, reinforced phenolic laminate
sheet stock. This material has exceptional strength and chemical
resistance, which makes it ideally suited for the most corrosive
environments. Composite panels are intended for use in corrosion-
resistant enclosures. Panel sizes are available for junction boxes
and UL/NEMA size enclosures. Composite panels may be drilled
and tapped but work equally as well with self-threading or thread-
cutting screws. Refer to the table for recommended mounting
specications.
