What is this?

I am a novice Shopsmith user. Today I purchased a Shopsmith Model 500 with a 520 table upgrade. I did look at the Shopsmith.com website. It looks like the lower saw guard is used for all(505.510.520) of the Model 500 Shopsmiths. I noticed the lower guard is missing a screw but I will replace it. What are the two plastic smaller pieces at the bottom of the photos and how are they use and assembled? I think the lower guard to the left is for the Mark V and the guard to the right for a 505, 510,520. Am I correct?

Welcome aboard.
Yes, the guard on the left is for the Mark V-500 and the guard on the right is for the Mark V 505 etc

The plastic parts at the bottom mount on the tie bar under the table.

Link to the manual for the left guard,

Thank you for responding to my inquiry. I guess I want to know which one of the components in the picture should I use for dust collection? Will either one work?

For use with the 520 table use the one on the right.

ok, I will use the one on the right as you indicated but which piece of plastic goes with the saw guard on the right? Thanks

If the piece of plastic is under the respecive saw guard it's totally coincidental. Does one piece of plastic goes with one saw guard and the other piece of plastic with another?

Also the one on the right.

Does the upper table configuration determine which lower saw guard is used?

Yes, they are not interchange able.

The upper guard on the 500 has a splitter and attaches to a block at the back of the table.

The 510 & 520 tables are larger, they are used with longer arbors as the blade is further in from the left edge, the upper guard is attached to the lower guard by a riving knife that goes through table insert.
