ABSTRACT:
A pipe guide adapter adds marking slots and marking edges to a pipe guide. The pipe guide adapter includes two body sections joined by a hinge enabling the pipe guide adapter to be in open and closed positions. The body sections each include a gripping end and a marking section. The gripping end has a diameter greater than the diameter of the pipe guide to circumferentially grip a portion of the pipe guide in the closed position and to attach to the pipe guide. A pipe is circumferentially gripped jointly by the pipe guide and the pipe guide adapter. A hinge pin is partially disposed in the hinge and extends beyond the hinge. The hinge pin allows tie pipe guide adapter to be aligned to the pipe guide. The extended portion of the hinge pin acts as a stop and a spacer between the pipe guide adapter and the pipe guide.
