Compromise Joints

Compromise Joint Bars are designed to join rail sections of different sizes while keeping gage and running surfaces in alignment. Compromise joints consist of two bars - an "outside joint bar" and a "gage side joint bar". Generally speaking, unless the difference between the rail head width is less than 3/16", right and left-hand joints are required. Unless otherwise specified:

bolt holes are alternately round and oval
bolts are not provided
rail joint opening is 1/8"

To Determine Right-Hand or Left-Hand Joint	To Determine Bolt Hole Locations

Stand between "HEAVY" rails, facing direction of the "LIGHT" rails. Indicate the joint to the right as "right HAND" joint, and the joint to the left as the "left HAND" joint.
