The Condux Jamb
Skid is a device for supporting sheaves or quadrant blocks inside
a manhole to pull cable into underground conduit.
By positioning the top of the jamb skid against the underside of
the manhole opening, and using the camlock foot pedal, setup can
be done in a fraction of the time it takes to install a hanging sheave
assembly. Pulling tension actually increases the stability of the
jamb skid during the pull. No dangerous breakage of chains or straps.
The Jamb Skid is especially useful when there are no pulling-in irons
available, or when the existing irons do not align correctly with
the duct opening. The Jamb Skid can be placed anywhere within a 360° radius
inside the manhole.
Constructed of solid aluminum, the Jamb
Skid is both strong and lightweight. In most instances it can
be installed by one person.
The complete unit is created by combining a base unit with one
of several extension units, depending upon the height required.
Locking 1 1/4" (32 mm) pins, allow the height adjustment of
the Jamb Skid. Also, the width adjusts to accept all Condux sheave
assemblies up through 8" (203 mm). 10,000 lbs. (44,480 N)
cable tension load rated.
