Our take on the Master Lock Group Lock Box s600

The Master Lock S600 is a wall-mountable lockout/tagout group lock box made of 430-grade stainless steel with an impact-resistant viewing window. It holds up to 19 padlocks so a crew can each attach their own lock to a shared isolation point during maintenance. It measures 12 in deep by 5.67 in tall and weighs about 2.43 kg. At $30.00 at eBay as of November 5, 2026, it sits at the low end for a stainless lock box, though five stores carry it new.
