I have my collection stored in 3200 count boxes, and when I add new cards to my collection I actually use a thick hardcover book to prop up the end of the box so that nothing falls over while I am filling the rows.  I have done this as well working with single row boxes.  Was just wondering if anyone else does this as well, or if there is a different technique that others know that might work better.  I don’t think I have ever seen this mentioned before so curious to see what some of the responses are. 

Yes, I always slant the box to fill it. How else would you keep the cards from sliding down?

I saw someone mention putting a strip of duct tape along the bottom of the row so the cards don't slip. I imagine it slightly increases the risk of damage but if you're careful it sounded like it had potential 

That might prevent sliding, but won't prevent them from falling over.

FWIW, I slant too. Whether it's putting something into my 5K boxes or my sets into their 800ct boxes, I always slant until done. If I know that padding will be needed I put that in first, put the cards in, then the other buffer padding.

Very true. I suppose that works best for toploaders and the like when boxes won't be full, not so much filling. 
 

To the OP, yeah I also prop the box up at an angle lol

Slices of "pool noodles" work well.  You can cut them to the height of the box's rows - or lay them down for longer spacing - to fill incomplete rows.  Also, shorter ones cut to the width (i.e., just slightly wider) can give you a convenient, sliding spacer that will hold enough to stop card tipping as you fill the box.

How about a piece of a pool noodle a bit longer than the width of the row?

Maybe I'm low tech, but I just use plastic bags, either from the grocery store, although those have limited availability now, or larger ones I can get at work to put in the unused section of a box row to hold the cards up.

I use the cardboard rolls from paper towel or toilet paper rolls.
