ADJUSTABLE GIBS TYPE BFS

CAD models are available in the tables below.

Note: The Spieth Gibs can be bolted to the side by screws through the clearance holes d1 or to the slide using the threaded holes d3.

ORDERING EXAMPLE:

To order BFS Gib with plastic lining with .015 fitting stock:

H = 1", B - 2", L = 12.0"

Order: SPIETH Gib BFS 1.0
