. . . . . . . . . . . . .((All Models)                 

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.
