Master Lock® Blind Flange Lockout Device, Large, S3924

The Master Lock Blind Flange Lockout device is a physical, best practice solution for pipeline maintenance. The adjustable cup allows for a secure fit that conceals and locks out access to nuts holding a blind in place. Workers can perform maintenance with confidence that the blind they placed on a pipeline will not be removed until all workers have removed their padlocks. 4 locking holes allow for multiple workers to lockout device at one time. Device fully conceals flange bolts preventing access to the blind until all work has been completed. Adjustable device provides a tight fit, adapting to multiple flanged pipe applications. Recommended for use with nut diameter from 3/4in to 1-1/8in (19mm – 28.7mm). Durable aluminum and hardened steel construction withstands conditions indoors and out.
