Crank-Operated Benders
Models 412/424
These portable benders are vise or bench mountable for
easy action and fast accurate bending to 180°. Two models
are available to bend tube sizes 4 (1/4”) through 24 (1 1/2”).
Exactol benders are designed with a worm-gear drive with
a 60 to 1 gear ratio to allow accurate bending with minimum
effort. They bend aluminum, copper, annealed steel and an-
nealed stainless steel without kinks or wrinkles. Easy crank
operation permits continuous production without excessive
operator fatigue; for use in tube fabrication shops, in the field,
or in factory maintenance departments.
A video (on DVD) is included to provide proper instructions
for use.
