KLS 70mm Disc padlock, available keyed differ and keyed alike.
A simple solution for locking of container arms. Supplied with 2 x keys per lock
No specific security rating to this lock as it is really designed as a deterrent, to be used in conjunction with a lock installed in the locking shroud.
For a higher security solution for the arms of a container, try an ABUS or Squire alternative.
For other security for the container locking arms, also see the Bulldog CT range of locks.
