Plug-In Chain for Frame Lock shop the largest and most affordable!

Frame lock plug-in chains

Many frame locks have a side opening to accommodate the insertion of a plug-in chain, for additional anti-theft protection.
The special plug-in chain is attached to the frame, by threading the pin on one end of the chain through the bicycle frame and a ring on the other end of the chain, after which you can easily click the chain's pin into the frame lock's opening.
You unlock the chain using the frame lock's key.
In other words, you need only one key to unlock both the chain and the frame lock itself, with even better protection.
Frame locks usually have an average anti-theft prevention level (rated in the Netherlands as ART-2), the minimum level most Dutch insurers demand when you're taking out bicycle insurance.
This is a decent safety level, but when you regularly park your bicycle in high-risk places, a second lock or the addition of a plug-in chain is always a good idea.
If you're looking for a proper plug-in chain cover for the plug-in chain, Hollandbikeshop.com also has those for you, in many colors, often printed with a logo.
Anyone who prefers a plug-in cable to a plug-in chain can also find everything they need at Hollandbikeshop.com.
