Review: Great Product - Well constructed and very Strong and very well made
Review: Combo lock - A good heavy duty lock. To change the code with the special key is easy, however after changing the code the lock was stiff to open, I thought it was jammed, a bit of persuasion, checking the lines are correctly lined up it came apart, (much to my relief). I've since applied some oil to the internals and moved the spindle in and out to free it up.
