Product Description


Labor-saving tie rod
construction hardware

Stud-lock is the result of combining our
field tested condu-lock and a threaded stud.
This component will allow one person to
reinforce duct without assistance. The
threaded stud extending out of each end of
conduit will allow the installer to easily find
pre-drilled holes in both insulated and
non-insulated duct.

Stud-lock keeps the conduit in place for
fastening the sealed washer and locknut
outside the duct wall.
