Easy to use holder to help drive screws into wood at specific angles. We have a 90, 75, and a 45 degree holder. Get your screw started at the right angle and then the holder pops right off. Enjoy!
Update... The 1x4 files are exactly 0.75" wide and have two rectangular guides for screwing into 1x4" or 1x6" boards (we used them when we built bird houses). Line them up to help drive the screw straight in the middle of a adjoining board on the other side. I also altered the height of the drive straight so that if you are using a 2" screw, you know where to stop before the screw pokes through the other side of the 3/4" thick board (1 1/4" tall).
