11. The replacement cleaning blade of claim 1 , wherein the replacement cleaning blade is capable of tightened installation onto a first mounting frame projection having a thickness of about 0.5 inch and a second mounting frame projection having a thickness of about 0.75 inch.
12. The replacement cleaning blade of claim 1 , wherein the replacement cleaning blade is capable of tightened installation onto a mounting frame projection with a gap between the insert channel and the mounting frame projection that is from about 0.1 inch to about 0.5 inch wide.
13. The replacement cleaning blade of claim 1 , further comprising a fastener comprising a screw including a drive head and a shank comprising a threaded region within about 0.25 inch of the drive head.
14. The replacement cleaning blade of claim 1 , wherein the second insert wall comprises a solid wall portion opposite the hole in the first insert wall.
15. A belt cleaning system, comprising:
a mounting frame comprising a projection;
a replacement cleaning blade according to claim 1 installed onto the projection.
16. The belt cleaning system of claim 15 , wherein the mounting frame projection is devoid of through-holes.
17. The belt cleaning system of claim 15 , wherein the mounting frame projection comprises a plurality of through-holes.
18. The belt cleaning system of claim 17 , wherein the replacement cleaning blade fastener is offset from the plurality of through-holes.
19. The replacement cleaning blade of claim 1 , wherein the replacement cleaning blade is capable of secure installation onto a belt cleaning mounting frame projection with a fastener that extends through only one of the first insert wall and the second insert wall.
20. A replacement cleaning blade for installation onto a belt cleaning mounting frame comprising a projection, the replacement cleaning blade comprising:
a blade body comprising a base region and a distal cleaning edge, the base region comprising a channel for engaging a mounting frame projection;
positioned on at least one side of the channel there is a layer of urethane material and an adjacent layer of metal; and
a hole configured for receiving a fastener and extending through the layer of urethane material and the layer of metal;
wherein a portion of the hole extending through the layer of metal comprises an internal thread; and
wherein the replacement cleaning blade is capable of installation onto at least two different configured mounting frames, the configuration difference comprising at least one of:
number of through-holes disposed in the mounting frame projection;
position of through-holes disposed in the mounting frame projection; and
thickness of the mounting frame projection that engages the channel.
21. The replacement cleaning blade of claim 20 , wherein the layer of urethane material is proximate to the channel.
22. The replacement cleaning blade of claim 20 , wherein the layer of material is proximate to the channel.
23. The replacement cleaning blade of claim 20 , further comprising a fastener disposed in the hole, and wherein the fastener comprises a set screw.
24. A replacement cleaning blade for installation onto a belt cleaning mounting frame comprising a projection, the replacement cleaning blade comprising:
a blade body comprising a base region and a distal cleaning edge;
an insert disposed within the base region, the insert comprising a first insert wall and a spaced apart second insert wall defining a channel therebetween for engaging a mounting frame projection; and
a fastener extending through the first insert wall and configured to press against a first side of a mounting frame projection to affix the replacement cleaning blade to the mounting frame projection;
wherein the second insert wall presses against a second side of the mounting frame projection so that there is no need for a fastener to extend through the second insert wall to affix the replacement cleaning blade to the mounting frame projection.
