two identical handles are configured for insertion into the core of a stretch - wrap roll . a substantially rigid hand grip is forward on each handle so that the hand grips can be grasped in the two hands for position guidance of the stretch - wrap roll . the handle grips can be carried in the gloved hand and can be run free or squeezed for braking control during stretch - wrap film winding . each handle is molded of synthetic polymer composition material to be sufficiently rigid to provide the necessary support , but the plug inserted into the core is configured and sized to be somewhat resilient to facilitate insertion into and removal from the core .
