The Master Lock Latch Tight™ 498A Portable Group Lock Box allows you to secure each lockout point on a piece of equipment with just one designated lock.  Capture the keys from those lockout points by placing them in the lock box.  Each authorized employee locks one personal safety lock onto the Master Lock Latch Tight™ 498A Portable Group Lock Box, removing them only when their work is complete.  Exclusive Latch Tight feature ensures that keys cannot be accessed until the last lock is removed.
