Product Description

What Kind Of Chain Is This?
This is a true security chain, made from square, case-hardened links to resist cutting. Laclede recently changed their heat treating process to make this chain 62-65 HRC. Made from quenched and tempered alloy steel with an electro-galvanized finish for corrosion protection. Laclede calls it "Lockdown Chain" for a good reason, and at 3/8" (10mm) in diameter, this chain is considered by many to be the ideal size.

What About The Lock?
A true, high-security padlock made to work with square security chain. Its heavy-duty design will certainly be a deterrent to any potential thief. This beefy padlock weighs almost 2.5 lbs. You may not want to put it in your pocket, but you'll be happy to secure your precious equipment with it. The brass lock body is 3 mm thick and hardened to 50 HRC. The shackle / pin is 0.43" and is nickel-plated. The lock also ships with three single sided keys designed to activate the 5-tumbler design, and the keyhole is protected with anti-drill steel. This lock works with 3/8", 7/16" and 1/2" security chain.

Questions & Answers

I have seen your company make a video showing the 3/8" Pewag chain not being able to be cut by bolt cutters, but does the 3/8" Laclede hold up the same way as the Pewag?
1 Answer
We have not done a separate video on the Laclede chain, but we plan to at some point.  We can say that so far, it appears to be just as tough to cut.  And that makes sense, because both chains have the same general HRC specs and size (10mm).

Great Chain and Lock for Commercial Use
February 10, 2019
First of all this set is not for someone to carry around for Bicycle lock down. Lock is heavy and also chain. Before buying we cannot physically see these sets and we can't exchange or return. We could have a hard time trying to resale. I bought 2 sets of different sizes and am stuck with them. The customer service may not give you the best advice. On the other hand for commercial use or to secure a large item that will not be used daily like a trailer boat machinery they are great.

Merchant Response:Thank you Gerardo. Yes, it is hard to convey to someone exactly how big and heavy a given chain or lock is, until they can see it in person. We do have customers that use the bigger chains for bicycles and motorcycles, but we understand that not everyone wants to pack around the extra weight.
ProsCommercial use
ConsNot for bicycle use
