Just received 120 panel and it appears the strap would come through the plastic guide but it is very tight so what is the proper method of opening the closure? It seems there must be an easier method.
Never mind I figured it out you squeeze the plastic tab and it releases the end like a seat belt only instead of pulling up you squeeze down.
Glad you figured it out, it is a bit tricky the first time!
Now to figure out how to fold them back up after you use them!!
I find if I slide my forefinger underneath with my thumb on top and sort of snap my fingers, it flicks open.
