Ladder Holder (for Roof Rack Cross Bars)

I bought a ladder mount in this online store. Very convenient thing. I don't quite understand why it's called 'for a ladder'? I use it for other long items too. Well, whatever. The main thing is, I'm satisfied.

Everything is very convenient. Thank you

I bought crossbars and mounts for the ladder in this online store. Installed them. For now, I use them only for transporting the ladder. Satisfied.
