## Description

Product Description Our security chains are made of hardened steel with a special anti-corrosion coating which makes them ideal for outdoor use. The links are not round like on common chains, but are square-shaped which is a lot more effective against attacks with tools. The chains also feature a nylon sleeve to prevent paint work and chrome from scratches and damage. From the Manufacturer ABUS 12KS 6' Maximum Security Chain and Sleeve.

Review: Works great! Just not very long - Very thick chain. Not super long, so you put it around your wheel and maybe the frame or swing arm with a U-bolt lock. The price is good, quality is awesome, no one is cutting through it quickly. Easy to use, looks sturdy and deters anyone looking for a quick steal. Get a good sturdy lock though, it’s only as good as the lock you put on it.
Review: If you don't want your bike stolen, get this with a high-end padlock. - I had my first ever road bike stolen and vowed it will never happen again. Previously, I had used one of the OnGuard U-locks (don't remember the model name/number because I purchased it 11 years ago), and it was nowhere to be found when I realized my bike was stolen. After I bought a new road bike, I did an extensive search of the major heavy-duty locks out there. What did I find? Numerous videos of these so-called super high-security Kryptonite U-locks costing $100+ getting picked in seconds or cut in minutes, not to mention videos of all kinds of cables getting cut like butter. Combination locks are laughable. There are all kinds of marketing gimmicks out there, including thin cables surrounded by a thick layer of rubber/plastic material and anti-theft protection (there is ONE account of a successful claim through the first 4 pages of google search but who knows if that is real; FYI, you need to submit the broken/compromised lock but most thieves take the lock with the bike). After spending days researching different combinations, here is the most secure combination I have found: A heavy duty chain + padlock that cannot be easily picked. Also, a digital U-lock as an added security measure. - Heavy duty chain: There is a video on YouTube that compares different chains. 12KS is the model that was tested in the video. It takes 4-5 minutes in ideal conditions (flat on the ground, allowing a thief to use his/her entire body weight) to cut using a giant bolt cutter. I can't imagine anyone being able to cut this with a bolt cutter if it is several inches off the ground. - Padlock: Again, a quick YouTube search will reveal how easily some of these can be picked. I won't endorse any particular company, but get one that has multiple discs and is not susceptible to hacking with a bump key. The best ones appear to cost $100+. - Digital U-Lock: The concept of keyless, digital locks with thick shackles is promising. There are several different startup companies competing for the next big market. Most of them are shipping their products around September, so we will see how easy/difficult it will be to hack these. PROS: - Very, very tough - Short (makes it more difficult for thieves to maneuver) - The two squares at the ends interlock so that you can use a padlock with a very thick shackle CONS: - Heavy. 4 lbs. - Limited versatility because it is only 2'. Wish they sold a 3' one. OVERALL: Highly recommended, especially for those in SF and NYC.

## Features

- Premium Quality: Our security chains are made of hardened steel with a special anti-corrosion coating which makes them ideal for outdoor use. Each link has a thickness of 1/4", inside height of 1 1/8" and inside width of 3/8".This chain requires 4 tons of cutting force to break through the hardened steel.
- Theft Deterrence: Our chain cannot be compromised by typical aggressive burglary attacks. Each individual link is unique in that the shape is squared rather than round. The squared link construction makes it almost impossible for theft tools to get a secure grip on the chain to cut. The thick hardened steel is extra resistant to sawing and the welded finish makes prying insurmountable.
- Secure Anything: ABUS square link security chains are utilized by both industrial and consumer users. Our customers trust this chain to secure their commercial/residential properties, containers, bikes, gates, fences, trailers, ATV’s, motorcycles and much more.
- Scratch Resistant: Traditional security chains expose your items/property to potential damages and scratches when in use. ABUS security chains feature a nylon sleeve to protect your property from scratches and damages while in use.
- Synonymous with Security: ABUS has been manufacturing and innovating security technology since 1924. When it comes to protecting lives and valuables, ABUS provides security solutions to help you feel safe and secure.

### ⭐⭐⭐⭐⭐ Large strong chain
*by I***E on November 16, 2025*

The chain has large links and may not be suitable for certain task such as a gate. It is suitable for locking up equipment and hopefully intimidating to thieves so they don't attempt to steal your stuff.
