The MF0055 is a set of four open "U" slot mounting feet molded in light gray ABS plastic for the larger RP Series water-tight enclosures: RP1450, 1455, 1460, 1465, 1610, 1615, 1630 and 1635 only.

The kit comes with hardware for wall installation: 4x M4 x 8mm self-tapping screws, 4x M4 x 25mm self-tapping wall screws and 4x wall anchors. The ABS material carries a UL94 HB flame rating. Each foot measures 51 mm x 25 mm x 6 mm (1.99 in x 1 in x 0.24 in), shown on the drawing as 50.42 mm [1.99 in] x 25.42 mm [1.00 in] with a 4.13 mm [.16 in] through hole.

It is intended for RP1450, 1455, 1460, 1465, 1610, 1615, 1630 and 1635 only; smaller RP sizes use the MF0040, MF0045, MF0060, MF0061 or MF0300 kits. The RP Series enclosures these feet serve are gasketed ABS and polycarbonate boxes designed to meet IP 65 and ideally suited for mounting printed circuit boards or components.

The MF0055 ships in a bag at a listed shipping weight of 0.08 lbs (0.04 kg), and it is REACH and RoHS compliant. The series specification lists the mounting feet kits in sets of 4. For a version of the enclosure with a bottom flange instead of separate feet, the manufacturer points to the RPBF Series.
