The R588-080-080 is a set of variable cover plates and gaskets for the R250 Series mobilCASE extruded aluminum enclosures. Instead of closing a single body, variable style end plates are sold in a set to connect two extrusions side by side, letting designers build a larger, multi-section portable case from standard mobilCASE bodies. This set joins two 80 mm profile extrusions.

According to the series table, the R588-080-080 is used to join aluminum extrusion series R250-080 or R251-080 TO R250-080 or R251-080. Either the one-piece closed body (R250) or the two-piece "clam shell" body (R251) can be used on each side, so the same set suits any pairing of 80 mm profile bodies.

The plates are heavy duty diecast aluminum painted with textured black powder paint (RAL 9005). Each set includes the cover plates, thermoplastic black gaskets and mounting hardware. The part data lists the material as aluminum and the colour as black, and the manufacturer's short description for this number is "ROLEC PG CONNECTOR".

The shipping weight is 0.5 lbs (0.23 kg) and the set ships in a box. The R588-080-080 is RoHS and REACH compliant. The extrusion bodies themselves are ordered separately.
