Specifications include, but are not limited to: General Specifications The plow edge blade shall consist of individual steel segments encased in rubber with steel bushings positioned on 12" centers for mounting to the plow. Each segment shall be milled to a special shape and profile and inserted with tungsten carbide bits, brazed in place along the wear edge.Finished SpecificationsThe finished blade shall be approximately 7/8" thick by 6" wide weighing 9.75 lbs. per foot. 11/16"ID steel bushings shall be located 1.5" from the top of the blade on 12" centers to facilitate mounting to the plow. Each blade shall have blade orientation embossed in the rubber casing.A 1/2" x 3" heat-treated 15B30 clamp bar shall be mounted on top of the plow blade to hold the blade on the plow. This clamp bar weighs approximately 5 lbs. per foot and has 11/16" square holes located on 12" centers to align with the bushings in the blade and shall be a part of the plow edge.Complete nut and bolt sets shall be provided with each plow edge.Steel Segment1.Cast steel 0.75” thick by 5” wide and 11.22” long.2.The top 3.125” of the segment shall be milled down to 0.625” thick.3.The lower, inserted section shall remain 0.75” thick.
