haven't been manufactured since the Environmental Protection Agency banned asbestos in 1989. You can get nonasbestos chutes, but even if you found some that fit your particular circuit-breakers, they would cost be tween $12,000 to $20,000 each-- probably much more expensive than preventive maintenance. Regardless, they scar much more easily than as bestos chutes.
