USA - The US Patent Office has issued patent 7,461,500 to J. R. Clancy for a "System for Determining Wear to Rigging System Lines," more commonly known as SureGrip rope. This is the only theatrical rope with a wear indicator, to tell users when the rope should be replaced.

SureGrip was developed by J.R. Clancy specifically to address the safety concerns of worn hand lines. Excessive wear is indicated by a "telltale" red thread woven into the rope - when red threads are visible, it's time to replace the line.

"Theatre safety is important to us," said Bob Theis, president of J. R. Clancy "and the development of SureGrip is part of our ongoing work to reduce risk backstage."
