The 120 series is a consumer-range set of brass [[pin-tumbler]] [[padlock]]s made by Lockwood. They range from 30mm to 60mm in width, with varying thickness shackles to suit, and come with three keys from the manufacturer.

__TOC__

== Features ==
Padlocks in the 120 series are assembled by Lockwood and cannot be dissassembled non-destructively. They are non-key retaining and feature relatively paracentric smaller keyways. The shackle is secured with two spring-loaded locking lugs, which leave the padlocks vulnerable to [[Bypass|shimming]] via the shackle.

=== Pinning ===
The 120 series contain 4-5 pins, which are a mix of spools and standard pins. The spools used in this series are different to the spools used in Lockwood's commercial range, which are commonly called Lockwood shallow spools.
