Conveyor Parts - Glass & Hard Plastic Audit update

I appear from the aether to ask another silly question.

There are several conveyors that lead to a hopper.  The product is scraped off the conveyor with a scraper.  On the sides of the scrapers are two plastic blocks that are angled to knock the edge product further into the hopper and away from the edge.  What would an officially sounding name be for these plastic chunks?  They're not scrapers, they don't touch the belt directly.  They're not guards.  Chute Scraper Edge Redirectors (2) might be my best guess.

If anyone out these has knowledge in the official part names for conveyor/chute cleaning systems that has a better name for these plastic paperweights, I'm all ears.  I've already spent too much time trying to find their official names online.

Directors?  Deflectors?  Probably something like that.

If they're held on with screws, I'd want them identified on whatever post-op sanitation and inspection logs you have.  Semi-fixed pieces on a conveyor system tend to eventually vibrate and fall off, and sending one to your customer would be really embarrassing.  Not as embarrassing as sending a customer a 14" metal scoop in a case of onion powder...  Not that I have experienced...  Never mind.

Guides

Ask what the operators and engineers call them.  Then call them that.  Presumably you're going to be asking people to do the audit so it's best to use a name already in use.  Photograph the items as well if you can so there's no confusion.  It is something I've found on some previous internal audits that when you dig into the glass and hard plastic inspections, what people think they should be checking vs. what was the intent of the person setting up the standard are not always the same thing.
