Senior moment - what are these called?

[sychnant]

The picket fence type gates that attach to the back corners (inside) of a lorry or trailer, and open up to edge the sides of the ramp when loading/unloading?

Does anyone have a clue what I'm on about??

Trying to explain to someone what these are, and need to find a picture to illustrate - but need to know what to call them to Google it

Thanks to anyone who can help a prematurely senile 37 year old. lol
