Flat Idler Pulley, 4"X3/8"

The 280-438 Flat Idler Pulley is a 4" metal flat idler designed to keep belt-driven equipment running smoothly with proper tension and tracking. Built by an OEM supplier (because sometimes the best compliment a pulley can get is “it fits like the original”), it’s a dependable replacement for a wide range of OEM part numbers across common mower and equipment brands.
