Jack Back Installation Video
The Jack Back Platform has
three industry-standard, front-facing
mounting holes, and another identical
set facing to the side. Rotating the entire
JB rotates both sets, so the jack can face
front, back, left, right! Your choice!
#1 • Starting Point •

#2 • The Fastest Option.•
Many installations are so simple and straight forward they can be done by just looking closely at the Illustrations. Find one close to yours, assemble the parts in a similar way, and bolt it on.
R&M uses Erector Set® and Lego®
logic - standardized parts assembled in different ways for different purposes.
