The CR Series combination padlocks, which are made of brass, are sold in 3 sizes: 20, 30 and 45 mm. The smaller two sizes have 3 rollers with 10 digits each, so the combination can be programmed with 1000 possible variations. The 45 mm model, on the other hand, has an additional roller, so it has 10,000 possible combinations.
We'll explain how to programme these padlocks very easily in this tutorial.
