(Now if only I could get my apprentice to leave the T-Locs latched when they're in the stack [wink])
Also, in case anyone wants an attic T-Loc with more capacity, I recently found it's easy to switch the lids between boxes. I bought a Sys3 and a Sys2 with Attic and switched the lids, which leaves plenty of room for the three 12V drills and one 18v drill I carry around + chargers and accessories.
