ABSTRACT:
A device for protecting the fingers while applying stretch film under tension from a roll of film wound on a core by braking the core manually from within. The device is a unitary flexible plastic body including a generally cylindrical hollow body sized to fit within the core, and a flexible brim at one end of the body. The brim has substantial width, so that it can be folded over the end of the core, and braking force can then be delivered to both the inside and to the outside of the core by inserting at least one finger into the device and then squeezing the core between the thumb and finger.
