The 20mm Polished Brass Padlock by Tri-Circle is a solid and robust padlock, the perfect choice of padlock for light security applications, including securing gates, chains, suitcases, and other outdoor applications. The build of the 20mm Polished Brass Padlock by Tri-Circle is of high-quality, solid brass. Using solid brass creates a corrosion and rust-resistant padlock, excellent at handling all weather conditions when used outdoors. As well as our application of solid brass, we also use hardened steel to bolster the padlock's shackle. Hardened steel gives superior cutting resistance, thus reinforcing the security of your padlock. Please note, we include three keys with your padlock.  Key MeasurementsLength: 20mmSuitabilityInterior useExterior useShedsGatesChainsWhat is IncludedOne padlockThree keysKey FeaturesBrass and Hardened Steel construction Product MaintenanceClean and oil regularly to maintain functionality
