Padlock GERDA KZT50 cast-iron shackleless 50 mm, model KZT50

GERDA KZT50 is a cast-iron shackleless padlock with a 50 mm body designed to secure gates, doors and outdoor equipment. The KZT50 model combines a solid cast-iron housing and a shackleless design to reduce the exposed metal surface that is vulnerable to cutting or leverage attacks. Its compact form factor makes it suitable for general-purpose security applications where a robust, weather-resistant lock is required.

Advantages

The cast-iron body delivers mechanical strength and impact resistance while the shackleless configuration minimizes access to the locking mechanism, improving protection against bolt cutters and prying tools. The 50 mm size balances compactness with a substantial locking mechanism, offering a practical solution for medium-security needs. The design is straightforward to install and maintain, and it is appropriate for outdoor use when paired with compatible mounting hardware.

Suitable for

• Securing pedestrian and vehicle gates
• Locking garden sheds, storage boxes and outdoor cabinets
• Protecting doors on workshops and small industrial units
• Securing temporary fencing and outdoor equipment

Key specifications

• Body material: cast iron for increased mechanical durability
• Lock type: shackleless design to reduce exposed cutting points
• Body width: 50 mm compact housing size
• Intended use: general-purpose external and internal security
• Operation: key-operated cylinder

How to use

Install the GERDA KZT50 by aligning the padlock body with a compatible hasp or locking keeper that fully engages the internal latch. Insert the key and rotate to retract or extend the locking bolt according to the installation orientation, then remove the key to secure the lock. Ensure the mating hardware is correctly anchored to avoid transferring excessive load to the padlock body. For outdoor installations, position the lock so that drainage is possible and the keyhole faces downward if feasible to reduce water ingress.

Usage recommendations

Regularly inspect the lock for signs of corrosion or wear, lubricate the cylinder occasionally with a graphite or silicone-based lubricant, and replace mounting fasteners if they show deformation. Use the GERDA KZT50 with sturdy hasps and properly anchored fittings to achieve the intended level of mechanical protection.
