Pursuant to the lease, SprintCom maintained an elevated platform on the roof that had a metal
grate surface that people could walk on to check equipment.
According to a company catalog, the Yellow Fellow featured 52 total inches of concave and
grate surface, adjustable front and rear concaves, an adjustable grate behind the cylinder and a moving grate under the beater.
Grate wear that causes excessive gaps between the hammer and
grate surface will harm shredder efficiency, affecting both product density and production rates.
