    Product Description


    Mammoth Thatcham Approved Chain 12mm with Shackle Lock

    If you are looking for the ultimate in security then this Thatcham approved chain lock does the job. 12mm square link Cro-Mo steel is formed into narrow links that provide exceptional strength while greatly reducing any leverage a potential thief may apply.

    The lock body is made from hardened steel and uses a double bearing mechanism and reinforced cylinder plates to make it incredibly resistant to drilling and picking. The lock closure shackle uses hardened Cro-Mo steel to continue the highly secure features.

    Insurance companies will often specify certain criteria for locks and immovable objects before granting cover for the actual value of the bike and not some nominal figure. Thatcham approval is equivalent to Sold Secure Gold standards ensuring you have the best coverage.

    This Mammoth security product has been evaluated against The British Insurance Industry's Criteria for Vehicle Security using specific tests to indicate the effectiveness of the product. It is recognised as a Thatcham Approved Device Category 3 Mechanical Immobiliser.

    Key Features:
    • Super Heavy Duty Lock
    • Thatcham Approved Chain
    • Sold Secure 'Gold' Equivalent
    • 12mm Cro-Mo Square Steel Chain
    • 1.2m Chain Length

    Top end Shakle lockReview by socaplid
    Looks to be a high spec security chain and lock as publicised .Had some locks in past this one for the money seems as good as if not surpasses those.Excellent value for money.Would advise purchase in conjunction with Some form of Ground anchor for use at home. (Posted on 12/10/2017)
    Good quality at a reasonable priceReview by wbossons76
    I looked at the Fahgeddaboutit which is the highest standard, and I looked at the Oxford line for an economy priced lock. My opinion is that the Thatcham is very close to the Fahgeddaboutit and is priced so that it won't break the bank. I think there is like 1 mm difference in the thickness of the chain -- not enough for me to worry. If you can cut this chain, chances are you can cut the gold standard as well. I am very impressed and feel my bike is safe when parked and locked with this chain. (Posted on 12/07/2017)

    Best value thatcham I could findReview by tomw2004
    I use it with a ground anchor in my driveway on front wheel. Too heavy to carry around in my opinion. Long enough for my purpose.
    Padlock a bit awkward with removable shackle but lock mechanism smooth. Chain crosses over with a long link.
    Highly visible which is good and nylon chain cover seems reasonably robust.
    All in all a good lock. (But) nobody has tried to defeat it yet.
