D-rings, D-ring mountings, padlocks, connecting chains and the position of the thigh bands on the thighs, are all a part of the equation that limits the separation of the thighs. It is how far you can separate your thighs that governs how effective thigh bands are. And it is thigh separation that affects accessibility.
There have been countless discussions on this forum about these details, made worse by many posters choosing to use short sentences or even clauses to ask, and answer questions about this subject. This results in a continuous stream of these details - "boring!" π€£
Just a suggestion, but for those interested in this subject, just ask, and answer:
"What is the maximum allowable separation possible of the two thigh bands and where are they positioned on the thighs?"
It keeps it simple, and answers can be really short.
I'll start the ball rolling:
My daily maximum thigh band separation is 6cm, and at night for bed, it is reduced to 2 cm. My thigh bands are at mid-thigh.
What else do you need to know ... that I am willing to answer? π€£
