Abstract
Abstract A protective sleeve that can be slipped over the knurled barrel of a flashlight or similar article to protect surrounding objects from the abrasive action of the knurling is composed of a resilient slip-resistant vinyl. When applied over the barrel of the flashlight, the vinyl sleeve provides a non-abrasive but slip-resistant surface for gripping. The inside diameter of the sleeve is less than the outside diameter of the barrel of the flashlight, and a household detergent is used as a lubricant to facilitate slipping the sleeve onto the barrel of the flashlight.
