Product Description

This is Laclede's take on a security chain, which they call "Lockdown Chain". It sells extremely well, and since Laclede changed their heat treating process to make this chain even harder--62-65 HRC--we are confident it's going to sell better than ever! People simply trust the Laclede brand. They are a domestic manufacturer of many types of chain, including high-quality overhead lifting chain, tie down chains and tire traction chains. You can literally find their chains in use all over this great country--construction sites, passenger cars, marine applications, you name it, Laclede is there. They are adaptive too, willing to make changes with their engineering to keep up with modern demands. For example, their Lockdown Chain used to be thru-hardened but with a lower HRC rating. Laclede's design team determined their chain would be even tougher to cut being case-hardened yet with a much higher HRC rating. They brought this change to market quickly, and now have a security chain that stacks up against ANY competitor.

What Size is This Chain?
Many customers believe this chain is the "perfect" size. At 3/8" (10mm) in diameter, it feels and looks beefy without being too big and cumbersome. This chain is made from quenched and tempered alloy steel with an electro-galvanized finish. It is worth noting that Laclede is the primary chain manufacturer we use for building Grade 100 chain slings because we trust their quality so much. This chain is available by the foot with quantity discounts available, or in kits paired with Laclede's super tough padlock.

  • Square, case-hardened links
  • Made from quenched and tempered alloy steel
  • Electro-galvanized finish for corrosion protection
  • Designed for securing valuables such as construction equipment, trailers, ATVs and water crafts

What is the Breaking Strength of this chain in lbs?
1 Answer
Because this chain was not designed and tested like rigging chain--such as Grade 70 or Grade 100--the manufacturer does not have this information readily available. The emphasis in design and testing was on the HRC rating. Still, we have asked for a number and if one is provided to us we will post it live on the site.

Can this be cut with bolt cutters?
1 Answer
We will give that a qualified "no". Assuming you're talking about "most" bolt cutters being used by one or two people in a standard environment, without a special setup (such as a chain comealong, etc.), then the answer is no. If rigged under the right conditions and using certain tools and mechanical advantage, it's possible. If you want to be sure your chain cannot be cut with bolt cutters, we recommend either the Pewag 12mm Security Chain or the Laclede 13mm Security Chain. Both are extremely hard, and the extra size makes them too much for bolt cutters to handle. We know, we've done our own testing!

Inspires Confidence
I purchased this chain to secure my tools and equipment at our commercial space after a bad burglary. Although I haven't attempted to cut this chain with a grinder or torch, I suspect it will pose enough of a deterrent that a criminal will likely look to easier pickings. A completely different class than the galvanized chain you find at the hardware store.
ConsMaybe too heavy for some people to handle long lengths on a daily basis.

Super Tough to Cut
If you are looking for a chain that thieves will hate, this is a good one. Its hardness all but eliminates bolt cutters as a cutting tool.
ConsTough to cut for the owner too!

Good security
I needed a short length of chain, 3 feet, to secure a portable safe. I wanted it to be safe from bolt cutter attacks. I don't think any chain is impervious to attack from a cut off wheel attack, but I was not worried about that attack in this location. I feel very good about this chain. It is attached to the safe, and the wall with very thick heavy duty hasps and a good secure padlock. Nobody is going to walk off with this safe, and it's contents by cutting this chain. I asked them to send me the link of chain that they had to cut to supply the short length that I needed. I don't have a lot of facility to test it, but this chain is hard. I couldn't hardly mark it. Let alone cut it. This chain looks good too. Part of the time it is viewable, and I don't mind it being out in the open at all. I'm glad that I got it. The small extra expense of this chain is well worth the piece of mind.
ProsBolt cutters won't cut it
ConsCosts more than regular hardware store chain, but well worth it
