The PRO TECTIC™ 4960 Frame Lock in black is a fast and simple way to secure your bike without extra accessories. Just get off your bike, quickly position the 8.5mm shackle, and you're all set. It's super easy to use and provides great protection in areas with low to medium theft risk. If you want even more security, you can easily add an ABUS CHAIN Frame Lock Chain as a second lock, which fits neatly into the additional lock housing. Features include an 8.5 mm thick locking shackle, a shackle, case, and locking mechanism support elements made of specially hardened steel. You can easily attach accessories to the locking mechanism on the lock housing. It comes in an R (key retaining) version that holds the key when the lock is open and an NR (non key retaining) version that lets you remove the key from the cylinder.

Using the ABUS Pro Tectic 4960 Frame Lock is a breeze. When you need to lock your bike, simply dismount and position the 8.5mm shackle in place. It's that quick! For added security, you can insert an ABUS CHAIN Frame Lock Chain into the additional lock housing. When using the lock, make sure the shackle is properly engaged. After use, keep the lock dry to prevent rust. If the lock gets dirty, you can clean it with a soft, dry cloth. Remember, the R version holds the key when open, while the NR version allows you to take the key out. That's all you need to know to keep your bike safe with this lock.
