Superstructure Parts: Expanding Roll Bar Kit
The PF161 expanding roll bar performs the same function as the PF16 roll bar . It is used with expanding frames. It consists of two 3/4" tube sections fitted into a 7/8" tube section . Holes are drilled to accommodate the spring buttons in the 3/4" sections which set the length of the roll bar.
The aluminum tube is 6063 3/4" and 7/8" outside diameter with a .058" wall thickness. The predetermined lengths are 21 1/4", 29 1/4", and 37 1/4".
This is a single unit. Often multiple bars are needed to make upper racks for the trailer.
