The L023 Flange Kit may be used as an "optional" installation kit for the Truckfridge(TF)/Cruise(CR) TF/CR49 model fridges. The kit consists of a left, right and top mounting flange. The left and right flanges have pre-drilled mounting holes for fastening the TF/CR49 into the cabinet. Note. The CR49 comes standard with the easy fix system thereby not requiring the use of the L023 for many applications.
