### Why It Might Seem Pointless — But Isn’t

Because the comb plate is subtle and blends into the escalator’s design, many riders barely notice it. Plus, it doesn’t look like a flashy or complex feature — just a simple strip. That’s why it can feel unnecessary or pointless at first glance.

However, imagine what would happen if it weren’t there: loose shoes, bags, or even small items could get stuck, leading to injuries or costly repairs. The escalator’s smooth operation depends heavily on this small but mighty component.
