Product Description

What Kind Of Chain Is This?
This is Pewag's original design for security chain, yet in a smaller, lighter size. It is surface hardened the same as the bigger 3/8" size (62 HRC Min.), yet because it is smaller, it does not offer quite the same level of security. But make no mistake, this chain is still very hard to cut and works well for securing bicycles, scooters and other similar items. On jobsites and in remote locations, a bigger chain might be a better choice.

How Is This Chain Different From The 3012 Chain?
For starters, the 3012 chain is no longer available. It is actually a traction chain that was not originally designed for security with a plain finish that was vulnerable to surface rust. The 3012 chain is also bigger at 12mm in diameter. While this chain is hardened 10% deep, the 3012 chain is hardened 6% deep. From a cosmetic perspective, this chain is silver while the 3012 chain is black.

  • Square, case-hardened links
  • While smaller and much lighter than the bigger 3/8" version, this chain still proves difficult to cut and is a great theft deterrent
  • Electro-galvanized finish for corrosion protection
  • Chain Hardness: 62 HRC Min.

Will the Pewag 9/32" security chain take a 3/8" lock shackle ?
1 Answer
If the dimensions hold true, then no.  The inside width on this chain is spec'd @ 0.37", just slightly too small.  I mean it's possible because there are minor manufacturing variations, but the answer based on the specs is no.

What is the actual link diameter? What size hole or opening is required to actually pass the chain thru? How does it compare to the 3/8" Pewag chain?
1 Answer
This chain is 7mm or 9/32" in diameter, while the larger chain you're asking about is 10mm or 3/8" in diameter. The 7mm chain is 0.95" at its widest point, while the 10mm chain is 1.43" at its widest point. Please keep in mind that industrial chains like these are subject to dimensional variation, so in examining each link, these measurements could change slightly. While both chains are hardened, the larger the chain, the harder it is to cut.

How does this chain compare to 1/4" stainless steel chain? Is it harder to cut?
1 Answer
Stainless steel chain is much easier to cut because it is not hardened--we have tested this ourselves. BUT keep in mind that the 9/32" security chain is also easier to cut than larger sizes of comparable security chain. For truly high security, we recommend security chain sized 3/8" and up. But for portability and ease of use, the 9/32" security chain is still viable.

Great Chain for Moderate Security
August 12, 2020
I have plenty of giant Kryptonite chains and u-locks but I wanted something lightweight that still offered moderate security. I'm glad to find that Pewag makes a 9/32" chain because I feel that it's the perfect balance between weight and security. I don't lock my bikes out in a dark alley overnight or a busy train station so I'm not too concerned about professional bike thieves. But I also would never trust a cable lock. I bought a 2 foot length and it's just enough to lock 2 bikes to a pole. I use a 3/8" Abus Titalium padlock because it's lightweight and still has an adequate 3/8" shackle. I wrap the chain around the seatpost and with the sleeve, it's tight and secure and doesn't rattle around. Great little chain.
  • Lightweight
  • Flexible compared to a u-lock
  • Moderate security

Outstanding Security
April 10, 2020
This is my second Pewag chain from Westech Rigging. I carry a six-foot length in my bicycle saddlebag, paired with a 3/8" shackle padlock. The chain secures the frame and both wheels to a bike rack or light pole. It deters bad boys with bolt cutters and is more versatile than a U-lock. In a row of bikes secured with absurd, 1/8" cable or marshmallow-y home store chain, Pewag is INTIMIDATING!

I also own the heavier, 10-mm chain paired with an Abus Granit lock. It weighs more, but is the only way to go when you absolutely, positively, want your bike to be there when you return.
  • Super-tough and super bright so it doesn't look like ordinary chain.
  • One link cannot slide through another, so you can't use a shackle-guard lock.

Pewag chains are the strongest and best for lockdown.

Solid Chain!

The chain and chafe sleeve work well. It is pretty easy to get up to 10 feet of sleeve over the this chain in a couple of minutes. Hoping this will be bolt cutter resistant.
  • lighter weight than the thicker options
  • not as bolt cutter resistant as the thicker versions

Great chain for bikes

This 7mm size is just right. Not too heavy but just difficult enough to cut that the thief will move on.
