In simple terms, a padlock has three major components; the Body, the Shackle and the Locking Mechanism, …it may also incorporate features such as a weatherproof casing, anti drill or anti cropping protection, etc.

Discus style padlocks - have no angular corners, so are often used with cycle security chains and cables, as well as being a popular choice for securing doors on sheds and beach huts, etc. When used as a door lock, they will typically be used in conjunction with the special shrouded discus hasp and staple set, which offers extra protection to the padlock shackle.

Shutter Locks / Anvil Locks - are typically used to secure the external (or internal) security roller shutters fitted to shop fronts. They are also popular for use with parking posts, motorcycle security chains, etc.

Conventional Style padlocks have a wide range of applications from low security applications like locking your toolbox, to high security uses such as securing factory gates or protecting motorcycles. They are typically available as; Open, Close, or Semi Enclosed Shackle types

Shackleless type padlock (shown with special hasp)

Shackleless Padlocks - this is a bit of a misnomer as the padlock does of course have a shackle, it’s just that it’s on the underside of the lock body and therefore unseen. This type of padlock can be round (like the one pictured) or rectangular, but typically, they are designed to be used with a special matching security hasp. Because of their design, these units are difficult to attack and over recent years, as well as being used on warehouse doors, etc, they have also become very popular for use on vans and other vehicles where they are used to secure opening double doors.

A "Close Shackle" padlock is one with built in shoulders, which are designed to minimise the amount of the shackle exposed, to a saw or bolt cropper attack. This type of padlock will normally have a higher security rating than an equivalent unit with a semi enclosed or open shackle, however subject to size and clearances, may not be practical for instance, to use where you need to secure 2 chain links together or require a padlock for use with a shrouded hasp, etc. To make them easier to use, many Close Shackle padlocks feature "removable shackles" which are fully released from the body of the padlock when it's unlocked.

An "Open Shackle" padlock will typically be easier to use where the shackle needs to pass through 2 chain-links (i.e, a chain securing two opening gates together), etc. As more of the shackle is exposed however, this makes it potentially easier to attack with a saw or bolt croppers.

A "Semi Enclosed Shackle" padlock is something of a compromise, but will often offer more flexibility in use than a Close Shackle padlock and improved security over an Open Shackle model.
