I recently had an opportunity to try
out the Hitachi NC65AC Concrete
Nailer (Hitachi Power Tools, 3950 Steve
Reynolds Blvd., Norcross, GA 30093;
800/546-1666; www.hitachi.com). The
tool arrived at an opportune time,
because we had just gotten underway
with a condominium project in
Keystone, Colo., that was designed to
be a two-story wood building set atop
an underground concrete parking
structure. The job presented a myriad
of wood-to-concrete connections.
I used the NC65AC for rough structural
connections, such as fastening
13/4-inch LVL balcony ledgers to precast
concrete retaining walls, and 2-by
mud sills to concrete slabs. I also used
the tool for exposed connections where
I had to secure cedar stair stringers to
concrete walls.
