Heat-shrinkable cable finger cots, commonly known as heat-shrinkable finger cots or heat-shrinkable gloves, are named for their shape similar to human palms and fingers. They are made of cross-linked polyolefin material and hot melt adhesive. At the branch, it shrinks when heated. The hot-melt adhesive on the inner wall will stick the cable tightly and play a role in waterproof and moisture-proof sealing protection.
