Who can best use this size of time capsule? In the past, it has been successfully used for high school dedications, company celebrations, and small city time capsule placements. The additional height is useful for certain larger items such as posters, banners, and flags. Or you can use the additional height for more books, papers, and photo albums.
Your archives box order includes the following items at no additional charge.
The time capsule is air tight after sealing. It is made of low corrosion stainless steel. It has a satin finish with welds polished smooth. It is water resistant, but should not be sitting in water over a period of 2 weeks (provide a way for the water to drain away). While its expected life is 75 years, the longevity of the time capsule protection can be more or less, depending upon the customer's conditions of placement. Use common sense and read all instructions that come with your purchase.All of our box time capsules come with sufficient packing to protect them from damage in transit. The packing may include foam insulation panels. You may place these panels around the outside of the time capsule while in placement. The R value is not high, however, so especially if you place the capsule near any outside wall, you need to think about how much insulation you need for your conditions, and add more if necessary for that placement.
