The 1457JEP is a replacement kit of two EMI/RFI end panels without mounting flanges with gaskets, listed by the manufacturer as the "1457J EMI/RFI end panels and gasket kit - 2/pack". It is intended for 1457-EMI series shielded enclosures whose part numbers begin with 1457J, and suits maintenance teams replacing damaged panels, engineers building spares for machined prototypes, or anyone converting between flat and flanged ends.

The panels are aluminum (die-cast alloy) in black, matching the series end panels that are painted in a durable black satin powder paint and are easy to machine for connectors and switches. In the 1457-EMI design, each end panel seals against the extruded body with a full-perimeter conductive foam/fabric gasket of Ni/Cu (nickel/copper) with CPSA (conductive pressure sensitive adhesive), and the kit carries an IP54 rating.

These are plain end panels without mounting flanges, matching enclosures ordered in the flat-panel version. If you need wall-mounting flanges instead, the flanged kits are 1457JEPF (2-pack) and 1457JEPF-10 (10-pack).

This 2-pack replaces both ends of one enclosure; the kit ships in a bag with a shipping weight of 0.08 lbs (0.04 kg). The 1457JEP is RoHS and REACH compliant. Enclosure assembly screws are sold separately in packs of 100 as 1457MS100, with a recommended screw torque of 5 lbf/in, and water-tight or EMI replacement gaskets are also available as 1457JPG-10 and 1457JEG-10.
