Locking Systems International has released a new padlock in its line of solid steel padlocks. The new FLEX(TM) Padlock gives the user the ability to change the lock cylinder themselves. This padlock was designed to use standard 7/8 inch cam lock cylinders such as Abloy, Medeco or Cobra cam lock cylinders. The body is made of solid steel and is hardened for maximum strength and security. The TF8500 comes with a 1 inch hardened steel shackle and the TF8520 comes with a 2 inch hardened steel shackle. The shackles are interchangeable and can be changed by the end user. For more information call 1-800-LOCK(5625)or visit www.lockingsystems.com.
