Purpose made for larger screwdrivers. Other options available were undersized and made for different kinds of screwdrivers. This was made from the ground up to accommodate larger handles, deeper bays and longer shafts. Also holds a custom 7 screwdrivers instead of the usual 4, also keeps to the gridfinity standard sizing so will pair nicely with other holders. Not made to hold ratcheting screwdrivers or flairs shafts. I use with Milwaukee screw drivers, Pittsburg screwdrivers, and old craftsman screwdrivers.
