Check the corners and flats of the mating guide profile. Its seating shape differs from the curved-seat Type A clamp.
Locate the Guide on Flat Seating Faces
The Type B head presents a square-profile seat that locates the rail on its flats. The retaining fastener holds the rail within that seat. Behind the head, the pin provides the connection for positioning the guide from its support.
Corner clearance matters as well as the profile's width. A rail with a different corner radius or section shape can sit unevenly in the head. Match the section before using the rod adjustment to set the lane.

Dimensions & Fit
Compare the guide's flats and corner shape with the seat drawing. Check the position of the retaining fastener against the rail's seating surface.
Maintain Rail Orientation Along the Lane
A square-profile seat helps locate the orientation of a matching guide section. Consistent seating at successive supports keeps the rail face presented to the product in the intended direction.
This matters where the guide has a distinct front and back or a shaped contact strip. Rotating the section changes where it meets the product, even if the lane width appears unchanged.
