If you buy a very good closed shackle padlock then the shackle itself will come fully out of the body when unlocked. This if because the guards or shrouds around the shackle (U Bar) must extend high enough, and all the way around, to prevent bolt cutters from accessing the shackle. As a result there is not enough room to allow the shackle to extend, and be retaining inside the body also. But this can be a blessing and a curse!


How can I retain the shackle?

1319710734_chain_attachementHaving a removable shackle can be a good thing since it allows more room to maneuver the lock into a tight space, for example on a container lock box. However, it can be a curse if you have many people using the lock and worry about it being misplaced.

We sell this product on the right which is basically just a loop clamp which is the riveted to a thin chain and then secured near to the place you are fixing the lock. You can only use this method on open shackle locks as a clamp would get in the way of the shackle access to lock. As a result you’ll have to resort to professional welding:


1. Take some chain where the width won’t extended over the top of the shackle and inhibit attaching it to a chain or hasp. Remember the chain is just for retention and not security so it doesn’t need to be heavy duty or hardened steel.

2. Cut the end loop in half

3. Weld directly to the shackle on the curved section (see below).
