The Lockwood 334B 45mm Brass Body Padlock is part of the high-security 334 Series, engineered for commercial, industrial, and high-corrosion environments. Built with a heavy-duty solid brass case and equipped with an 8.7mm boron, moly, or stainless steel Rapid Change shackle (variant-dependent), this padlock delivers exceptional strength, durability, and long-term performance. The 334B range supports multiple keying systems and includes options suitable for standard, high-security, and restricted keying applications.

Key Features

Solid Brass Construction: Heavy-duty brass case extrusion designed for reliability in demanding environments.

High-Strength Shackles: Available in Boron Steel, Moly Steel, or Stainless Steel for enhanced cut, pull, and corrosion resistance.

Rapid Change Shackle (RCS):
Allows quick removal of the shackle by turning the key and depressing the release pin—ideal for service environments and rekeying efficiency.

Double Ball Locking: Provides strong resistance against prying and torsional attacks.

Extended Shackle Options: Multiple shackle lengths available across the series (19mm, 25mm, 38mm).

Corrosion-Resistant Variants: Stainless steel models suitable for marine or outdoor environments.

Configurable Locking Function:
Standard as latching (non–key retained).
Can be converted to deadlocking (key-retained) by repositioning the cam plate pin in the cylinder assembly.

Commercial Suitability:
Ideal for gates, storage units, industrial sites, construction environments, marine hardware, and high-security installations.
