Group Lock Boxes

Master Lock Safety Solutions has introduced a new series of group lock boxes. All three models of the S600 series – S600, S601 and S602 – offer many significant benefits, including a clear, impact-resistant window that allows users to see keys are secured inside the box during a group lockout.


Manufactured from 430-grade stainless steel, these boxes are coated with a heavy-duty powder to provide maximum corrosion resistance and protection for all types of weather. Drain holes on the bottom offer an added safeguard by preventing rainwater and other liquids from accumulating inside.
