Arkansas City ? Interest in a product that helps move victims trapped in buildings down flights of stairs has been growing since the Sept. 11 terrorist attacks.

The 21-pound rescue device assembled in Arkansas City operates without batteries, electricity or motors.

The product, called Lifeslider, is a simple plastic sled that has recessed rollers and is equipped with nylon seat belts, quick-release fasteners, a rear steering handle and molded handholds for lifting.

So far this year, the company has sold 350 units. It recently sent 125 of the rescue sleds to the U.S. Department of Labor.

“The federal government really likes this (product),” said Trish Meier, director of operations for LifeSlider Inc. “We are getting more ready to go in to the Justice Department.”

Thermally formed plastic molds for the product are manufactured by another company, then sent to Arkansas City where all assembly is done.

A patent is pending on the product, as improvements are made, Meier said.
