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, set-up 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.
