Can’t quite fit your drill into that narrow space? No need to get a whole
new set of long bits. Just pop any of your existing 1/4" hex-shank drill bits
or driver bits into one of these extensions. The 12" extension allows most
people to reach an 8' ceiling without a ladder, and you can even line them
all up for 21" of reach! Not for use with impact tools. Each extension
includes a 1" #1 Plain Hex Phillips Bit and a 2" #2 Power Groove Phillips Bit.
