My Dad and me modified a standard Flathead Screwdriver Bit and made it fit perfectly in my Edwards 270-SPO and my Edwards 278B-1110! I’ve already pulled and reseted my 270-SPO at least 15 Times since we made that custom but and the screw still isn’t stripped!
As long as I carefully Open the Pull Station with 2 Hands and the Screwdriver perfectly aligned with the bit, then this Screw won’t strip!
Tell me what you think of my custom Bit?
