Safe

Safe

This large kit assembles into a completely transparent safe with a fully functional three-tumbler combination lock on the door. When the combination has been entered correctly, an additional turn of the dial past zero engages the bolt and withdraws it, allowing the door to open. 

Because all parts of the lock are made of transparent acrylic, you can see the operation of the code tumblers perfectly clearly. The pins that engage between neighboring tumblers are colored acrylic, so they stand out and demonstrate their function in encoding the combination. By watching from the front, you can figure out the combination. (You can even learn that every combination lock actually has two different combinations: one that works when you start by turning clockwise, and another when you start by turning counter-clockwise.)

If you like locks, check out our Pin-Tumbler Lock and Gift Card Lock Box kits. There are also sets that get you two or four lock kits together at a discount.

You can see how the combination locks works in this video of the stand-along Combination Lock kit, which is identical to the lock installed on the door of the safe model

Your model will arrive attractively packaged with all the necessary parts (including a screwdriver and wrench). The kit screws together in about 45-60 minutes, and does not require any special model-building skills. A detailed, step-by-step assembly video is available on our instructions page.
