• Dual Wire Coil Cord
  Provides redundancy so that even if one conductor is severed, operator has reliable path-to-ground with other wire
• Mono plug
  Designed to be used with a dual-wire wrist strap monitor. Not compatible with banana plug grounds.
• Use with resistive loop technology
  Continuous monitor which continuously verifies the proper resistance to ground of the operator
• Coil cord with molded 1 Megohm
  Current limiting resistor on both ground paths protects user from shock due to inadvertent contact with line voltage
• 4mm snaps are machined to precision profile from 300 seris stainless steel for a coonsistent and reliable  connection 
• Single (Snap-One™) snap head
  Allows operators to quickly and easily attach and detach the cord from the wristband
• Park-It feature on Snap-One™ snap head
  Provides convenient park staion for cord when not in use
• Custom manufactured right angle mono-plug
  Reduces chance of accidental disconnects, providing more secure ground connection
• Use patented (6,052,053 and 6,205,408) Dual Wire Wrist Strap with Semtronics Dual Wire Continuous Monitor
• UL listed
  Coil cord includes 1 megohm resistor, for your safety
• Date coded
  Providing lot tractability to ensure quality control
• Superior resistor connection
  Strain relief for superior reliability. Greatly exceeds ESD S1.1 Bending Life Test. Tested at over 11,000,000 cycles vs. the 16,000 requirement
• Superior warranty
• Made in America

What the ESD Association says about testing wrist straps:

Per ESD Handbook TR20.20 section 5.3.9.1 Wrist Strap Checkers - “Wrist strap checkers have historically been the primary tool for testing the operation of the wrist strap system including, the wristband, grounding cord and most importantly, the electrical integrity of the contact between the wristband and the wearer. Wrist strap checkers measure the resistance of the entire system.”Made in America, Superior quality
