Inquiry (采购产品): postal locks I have several hundred postal boxes without keys I would like to rent out. I need to replace the lock mechanism. The boxes themselves have little identifying markings. They say, 'Security' on the inside of the box door and look like standard commercial postal units of various sizes. How can I go about this? **** Hidden Message ***** Payton Cannon 159 Kaiulani Ave #201 Honolulu, HI 96815 USA Company: Recycled Books of Hawaii Phone: (808) 371-6961 E-mail: payton.cannon@gmail.com **** Hidden Message ***** payton.cannon@gmail.com
