A failure of the cord locking could lead to a mountain climber's fall, posing a risk of death or injury, the Consumer Product Safety Commission said Thursday.
The recall involves RescYou crevasse rescue aid that were made in batch number 12-12 and 03-13, the regulatory agency said.
The devices are blue and silver with mechanical ascendents, each using a cam that grabs the lifting rope. The rope is then allowed to slide, but only in one direction.
They were imported from Taiwan and sold at outdoor stores from June 2013 through January 2014 for about $125.
Mammut Sports of Williston, Vt., will replace the device free of charge, the commission said.
Consumers were advised to stop using the devices.
Consumers can call 800-451-5127 for information.
