Icemaster 50 Manual Gritter is ideal for spreading dry granular material onto frozen surfaces and roads.The spread speed and width of spread are controlled by the speed at which the Icemaster Manual 50 Gritter is pushed. An adjustable flow control mechanism determines the amount of gritting material released. We recommend that Icemaster Manual 50 Gritter should be used with Glasdon Icemelt. If grit or salt is used it is essential that the material is dry. Icemaster 50 Manual Gritter has a strong tubular steel frame and corrosion-proof plastic hopper. It is supplied flat packed for self-assembly and ease of storage.
