Bell's Visor Edge Rubber Profile Kit is the gasket material used to seal the visor on Bell's Advanced, Carbon, Pro, and Sport Series helmets that use the rubber gasket (not eyeport foam) to seal the visor. Bell makes aftermarket rubber molding kits primarily for helmets that have been custom painted, often requiring the rubber edge around the bottom trim edge and eyeport to be replaced. Rubber Profile Kits are made to factory specifications and are fire-retardant.
