The Faultless 100 line is excellent for general warehouse and factory applications.  The 108-2-1/2 wheel is a unique combination of durability, weight capacity, and low profile.  It is only  3-3/16 inches high and supports up to 200 lbs per wheel, making this metal wheel caster one of the most impressive and durable in Faultless’ 100 line.
