Beal Hot Protector Rope Protector – Made of glass fibre and aluminium, the Beal Hot Protector is a patented rope protector resistant to heat, welding spatter, angle grinder, or a blowlamp flame – for a short time. Magnets at each end seal the protector around the rope but can also be used to stick the protector directly to a metal surface. The magnets are polarised to allow multiple protectors to be linked together.
