Reviews

My fault for not looking at the picture more carefully before buying. The description even says INVERTED TYPE. The tool is quite well made but not what I expected or wanted. I have not come across a use for this type of strap duplicator yet but for the price of the tool relative to the shipping I will just keep them and see if a need ever comes up.

Q: What size should I order for instrument panel screw holes?

Instrument screws are usually a 6-32 so you would want a #35 bit. I would go with the number 30 duplicator to make the initial hole and then follow up with a #35 drill.

Q: What does the 6-1/4" and the 13-1/4" mean in the size?

Those are the lengths of the tool itself.
