KEY-BAK has been producing the most popular and widely used ID yo-yo for US government agencies for over 50 years. The patented Super48 Key Holder with spring steel belt clip features a shatterproof and extremely durable polycarbonate case.
The retractable Kevlar® cord is highly heat resistant, withstands high stress and offers extremely low elongation values. This Kevlar® fibre PLUS has been proven to withstand over one million pull-outs at 27 kg. The Super48 model also has a specially developed ball-and-socket lock on both sides, which only allows pull-out to the front and thus prevents unauthorised pull-out to the rear.
A practical alternative in the attachment options for card holders or keys and are widely used where a key, a company ID card, a visitor's badge or a normal admission ticket should always be within reach.
