• Patented (US patents 6,052,053 and 6,205,408) Dual Wire Wrist Strap provides redundancy
  Even if one dual wire wrist strap conductor is severed, operator has reliable path-to-ground with other wire
• Use with resistive loop technology continuous monitor
  Continuously verifies the proper resistance to ground of the operator
• Solid stainless steel wrist band stud machined to exacting tolerances and precise profile
  Ensures reliable path-to-ground connection to spring loaded 4mm stainless steel constant contact coil cord snap
• Durable, lightweight fabric
  Some users prefer the softness, comfort and flexibility of this material
• Has silver impregnated nylon knitted on inside for superior conductivity
  Reliably removes generated static charges
• Made with pure silver irreversibly bound to fibers providing both antimicrobial and anti-odor performance
• Adjustable
  Only one item to stock; may be fitted to almost all people
• Locking clasp
  Band locked so it will not slip
• Unique patented (US patent 4,662,695) adjustment design eliminates exposed conductive “tail” of band
  Provides added safety eliminating chance of providing inappropriate ground path

• Made in the United States of America
  Superior quality

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.”

Jewel™ Wrist Bands meet and exceed the Wrist Band and Wrist Cord requirements of ANSI/ESD S20.20.

ANSI/ESD S20.20 Paragraph 6.2.2.1 Personnel Grounding Requirement "All personnel shall be bonded or electrically connected to ground or contrived ground when handling ESD sensitive items. When personnel are seated at ESD protective workstations, they shall be connected to the common point via a wrist strap system."
