Product Description

What It Is
A true, high-security padlock made to work with square security chain. Its beefy design will certainly be a deterrent to any potential thief. It works with all of the security chains we offer in 3/8", 7/16" and 1/2" sizes.

Why You Need It
Because a good security chain is only as good as the lock you secure it with. This lock's pin is completely shrouded and even protected by the security chain. Thieves look for the quick and easy target, but with this lock, there are no shortcuts! No bolt cutter access!

How Beefy Is It?
Well, it 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 lock body is electro-galvanized too, so this lock will hold up to the elements. It ships with (3) single-sided keys. We know you will be impressed!

  • 3 mm thick, chrome plated, heat treated case (50 HRC)
  • Brass lock body
  • Brass keys with nickel plating
  • Heat treated, brass lock cylinder
  • Five brass tumblers
  • Stainless steel spring
  • Drill protection plate

from Idaho asked:
January 28, 2020
What are the spec measurements for the chain sleeves?  How much of a gap will a 3/8" chain link leave if used with this lock (gap that bolt cutters could access)?
1 Answer
3/8" security chain fits best with our 2-1/2" sleeve, which can be found here (there are specs on this page as well).  As for the lock, when used with 3/8" or 1/2" security chain, there really is not a gap that would allow access to bolt cutters.  That is due to the design of this padlock with the recessed chain pockets.  The bolt/pin is actually very well protected.

How hard is copying/replacing keys?  Is it a special order?
1 Answer
We do not offer key copying or duplication services, so you would need to check with a local locksmith.

Will it attach to TWO INNER links (neither being end links) of Laclede 3/8" security chain?

1 Answer
No, the links are just a little too short.  It will do this with the Pewag 1/2" Security Chain however.

from Clearwater, FL asked:
June 5, 2019

What is the model number for the already keyed one?  I want one ready to use.

1 Answer
All of these locks come keyed and ready to use.  The only real difference is that if you want multiple locks, you can choose to order them "Keyed Different" (meaning each lock uses a unique key) or "Keyed Alike" (meaning all locks take the same key).  Some of our business customers plan to use multiple locks, and they want all locks to take the same key so they can hand out keys to their crew and not worry about who has which key.

March 13, 2019
Will it attach to TWO INNER links (neither being end links) of Pewag 1/2" galvanized security chain?
1 Answer
Yes, but it is quite tight, and you have to position the links just right.  See attached photo.

from Brisbane, Queensland asked:
February 28, 2019

Will the Laclede 9/32" (7mm) Square "Lockdown" Security Chain work with this lock?  I can see that the gap in the Laclede 9/32" (7mm) chain is big enough, but I am wondering if there is some other issue I am unaware of.

1 Answer
Unfortunately no, it will not fit.  The chain pockets on the padlock are too deep for the chain to seat properly.  It is close, but it does not quite fit.

How does this lock compare to more expensive locks like the Viro locks?
1 Answer
We get this question a lot. This lock, in our opinion, is very good for the price. It's actually the lock we use at our own facilities, in the keyed alike version. Lock experts tend to agree the Viro locks are more pick-proof, and we would not argue that. But the primary concern, for us and most of our customers, is a lock and chain combination that cannot be cut with bolt cutters and acts as a good theft deterrent. We believe the Laclede locks satisfy this.

Way better than I expected
September 5, 2019
The pictures and specs are a bit misleading. In reality this padlock is way better. It has two solid side armor plates and anti-drill protection. I do not believe you can find better padlock in this price range.
ProsMassive Drill resistant Side armor plates just as thick as the rest of the steel armor

Worked so well that I bought another. Lock was damaged in a break in but thieves couldn't break it.

Merchant Response:Awesome! So glad it protected your bike!

Very Good

Had it for 20 days out in the weather still looks and works as new. It is so robust I think someone would have to have something like a torch to get it off, or make a lot of noise with some good sized machinery.
