What's the exact meaning of wide body channel?

I’m before the start of the business. I first practiced with Ninja Squeegee and bought Moerman Squeegee in case I needed rotation. In other words, I have never used it except for two products. There were many differences between these two squeegees. NXT-R rubber was surprised to hear a sound similar to BLACKPINK’s “Whistle.” lol

It’s a question.
Does the wide body channel simply mean that the channel is thick?

Wide body is best suited for 18” and up… the
standard slim channels are best for below 18”

And yes, to your question… they are called wide body simply because they are wider than the standard brass/stainless channels

Thank you.
It helped me a lot.
