Just bought two of these and I "think" I like them but it would be good if instructions were enclosed. There are two buckles on each strap, but there are no instructions on how to put these together to make it work. How are the two buckles used? Even the picture does not show how these are to be used
You feed the strap through the d ring, then pull the loop tight around the tank and stick the Velcro together.
The strap goes trough the buckle, Velcro away from tank, and then back on itself to "Velcro" together. Mine has a non-slip material sown on the tank side of the strap. I too wondered why there was no instructional material included with the strap. We got them so my wife could use both hands to carry the tank if my back went out.
