A comparable lock is required to match the impressive high-security Pewag chains, and the Italian Viro company makes some of the best in the business. Nothing is theft-proof, but the excellent pewag 12mm security chain with the Viro EuroMonolith pick resistant shrouded padlock requires an angle grinder to cut. Any of the pewag security chains with a shrouded lock is an ideal candidate as a theft deterrent to protect your bike, with highlights to their 10mm and 12mm sizes.
I dunno, that Ottolock looks like it could be cut pretty easily with a sharp pair of mini bolt cutters that fit in a front pocket. In the video it shows the lock is actually made up of several steel bands – when you try to cut them with bolt cutters, the bands slide against themselves, making it very difficult to cut. Yes, and angle grinder would go through it, but most people aren’t taking an angle grinder to a bike lock outside of a coffee shop in broad daylight.
Brindley sells the Pewag VKK 14×52 security chain in lengths from 1 to 5 meters in 0.5m increments. We’ve tested a 1.5m section, which comes with a Mul-T-Lock NE14L Grade 6 padlock. The Pewag VKK 14×52’s angle grinder attack time is at the upper end of average, and combined with its good results for a noisy sledge hammer and silent bolt cropper attack, its relatively low weight and hence portability make it an impressive security option.
Our biggest “Chain security” requirement has usually been keeping the ladder secured to the yard fence over the winter, so a heavy “Motorcycle” chain from the big box store has been good enough. Real “Security” chain for expensive motorcycles and other things is made by a company called Pewag, here in the US. Their main product is commercial “Traction chains” i.e. tire chains, which get ground down by pavement. No one is cutting this chain without making a scene.
You can use the Pewag security chain as a bike chain lock or a motorcycle chain lock. The 3/8″ Security Chain and 1/2″ Security Chain are used to protect more industrial items and facilities. Along with the hardened steel chains are chain locks that work with Pewag Security Chain for maximum security.
Having said all this, you will just have to accept that a chain lock is always going to be heavier than a u-lock that provides equivalent protection…. Kryptonite Kryptolok Chain Lock. Be careful…. You need to understand the different security levels of the different parts of this chain lock to get the best out of it, so check out my full tex-lock review here! And read how it even made my best lightweight bike lock list! If you want to know more, you can read my reviews of the Hiplok Gold chain lock and Kryptonite Evolution chain lock.
pewag chain vs angle grinder Related Question:
Can Pewag chain be cut?
By being the toughest chain, we mean the Pewag chain is the hardest chain to cut with bolt cutters or standard tools. This is because the 9/32” and 3/8” hardened security chains are hardened to 63 HRC 10% deep, while the 1/2” hardened security chain is hardened to 63 HRC 6% deep.
Are Square chains harder to cut?
The biggest reason is the hardened steel chain is squared, so it will not allow bolt cutters to cut through it. With the chain link’s squared shape and impressive chain hardness of 63 HRC, this is a bolt cutter resistant chain that requires tremendous effort to cut, unlike standard round chains.
Is there anything an angle grinder can’t cut?
The inspiration behind this creation is the natural defense mechanisms used by shells, grapefruit skins, and fish scales that makes them resistant from the attacks of various sea creatures. The material, named Proteus, cannot be cut using either angle grinders, drills, or high-pressure water jets.
What security chain is strongest?
Pewag VKK14x52 MAXIMUM Security Chain Certified to Sold Secure Motorcycle Gold standard, the Pewag VKK14x52 is the largest and toughest of the Pewag VKK range of security chains and provides maximum levels of resistance against bolt cropping, hacksawing and freezing.
What kind of chain Cannot be cut?
Hexagonal links (or square or trapezoidal) make it impossible for bolt cutters to get a grip. Chain sold by the foot at the local hardware store performs lifting and towing well, but not theft resistance.
What is a grade 70 chain?
Grade 70 chain is about 20 percent stronger than Grade 43. It is made from a heat-treated carbon steel that is incredibly sturdy and durable. Grade 70 industrial chains typically come in a gold chromate finish for easy identification – as well as protection from abrasion and scratches.
Which gold chain type is strongest?
Solid gold chains are the most expensive option, but they are also the strongest and most durable. Hollow chains are less expensive, but there is a potential problem with them: These chains are easy to break or dent, and if that happens, they are difficult to repair.
What grade of chain is hardest to cut?
Industrial chain is rated by grades; the higher the grade number, the more steel alloying elements it contains and the more resistant it is to the variety of loads a chain encounters, especially in tension. Grades 70, 80, and 100 are among the hardest and toughest available.
What material stops an angle grinder?
Instead, this Ferosafe stuff is a graphene composite material specifically designed to resist angle grinders and drills, and it’s made by a British materials manufacturer called Tenmat who have partnered up with Hiplok. Essentially this stuff disintegrates angle grinder blades!
Who or what is the weakest link in the security chain?
Security is about trust, and trust is generally considered the weakest link in the security chain. Social engineering is the science of getting people to comply with your wishes and concentrates on the weakest link of the computer security chain.
What is the strongest steel chain?
Grade 120 chain exhibits the strongest tensile strength of all steel alloy chains and is used for exceptionally heavy overhead lifting.
Is chain or cable stronger?
Strength, Load Capacities, and Work Environments Overall, wire rope is stronger than chain. The multi-strands of continuous wires give wire rope its strength, whereas a chain is joined together with links. These joins are the weakest part of a chain and can break under heavy loads.
Can grade 80 chain be used for transport?
Grade 80, a heat-treated steel chain, differs from Grade 70 in that it’s known for its excellent strength to weight ratio; therefore, it can be safely used for overhead lifting. Additionally, it can be used as a towing, safety, and recovery chain.
Will Grade 70 chain rust?
G70 chains are made from a higher strength, heat-treated carbon steel and have a load rating approximately 20 percent higher than Grade 43. The gold chromate coating offers them more resistance to rust and corrosion. These chains have become the most common grade of chain used on flatbeds.
What is grade 43 chain used for?
Typically used for container securement, logging, farming, towing, marine applications, and as general purpose utility chain.
