GERDA KMT90 90mm Solid Brass Pin Padlock with Hardened Steel Shackle, Keyed, 3 Keys, Security Class 6

Securing a warehouse roller door or a site container demands a lock that shrugs off cutting, drilling, and weather. The GERDA KMT90 pin padlock steps up with a 90 mm solid brass body and a hardened steel shackle, built for high-risk outdoor and indoor applications. Its pin tumbler cylinder resists picking, while the anti-drill plate and anti-saw pin blunt common attack methods. Three standard profile keys are included, so you can equip multiple authorised personnel from day one.

• Locking site boxes, tool chests, and storage units
• Protecting outdoor equipment, trailers, and machinery
• High-security applications in industrial and commercial settings

Good to know

While the KMT90 is built for toughness, regular maintenance will extend its life. Periodically lubricate the cylinder with a graphite-based lubricant and ensure the drainage holes remain clear. The three included keys are standard profile, but for larger keyed-alike or master keyed systems, consult with GERDA or a qualified locksmith. This padlock is not designed for use in marine environments with constant saltwater immersion; for such conditions, consider a model with additional protective coating.
