ABSTRACT:
A blind hole finder tool is provided which consists of a C-shaped spring member, with a pair of elongated arms, each extending from one side of the C-shaped spring member. A mechanism is on a distal end of the first arm for engaging with an original rivet hole in a top rail of a trailer. Another mechanism is on a distal end of the second arm, being in alignment with the engaging mechanism, for marking the hole location in new roof material after the new roof material is placed upon the top rail, so that the new roof material can be secured to the top rail at the original rivet hole.
