Hole-In-One® "F" Plunger Pin + Shaft
for locks needing a larger diameter pin
If your patient has a hard time getting their pin engaged in the lock, the Hole-In-One® may be the perfect solution. The Hole-In-One® comes with a specific pin made with a hole in the end of it and a long flexible rod. You simply cut the rod to the length you want (the longer it is, the better it works and less chance of failure), clamp it in a vise so about a 1/4 of an inch sticks out the top, then tap the pin down on top of it to create a pressed fit.
