Pick an pluck foam and Padded Dividers
Pelican Case Pick and Pluck -This is a very simple type of protection. All you have to do is pull out the half inch cubes wherever you don't need them an you've got instant protection. Depending on how deep the case, pick and pluck comes in one two or even three layers. A set of pick and pluck also includes 2 more layers of foam. A layer in the base of the case and the conguluted layer in the lid liner. Pick and pluck foam is a stock accessory to all Pelican Cases,
Padded Dividers- Padded dividers are really simple. Foam panels are wrapped in nylon and fitted with velcro ends so they can be positioned wherever you like
Double throw latches
For 25 years Pelican used classic c-clamp latch design, its simplicity made them famous for their strength and durability, that is why you will never see a pelican with springs that can corrode, or buttons that can get jammed with dirt or mud.
Pelican recently introduced a new design called the double throw latch. It features the same amazing strength, but opens with just a light pull. It is called the double throw latch because the secondary movement leverages against the case wall to release the latch. You will find this new design across the entire line of pelican protector cases.
Structural Foam Wall and Defelctor Ribs
Pelican cases are made with a unique structural cell molding process. Agents are mixed in with the polymer pellets, causing them to expand inside the mold.
This process takes about twice as long as conventional injection molding, but the result is a laminate structure that is lighter and more rigid than a solid core wall. The big advantage of closed cell wall structure is reduced fractures, if an impact does break a panel, the closed cell acts like a road block to limit the fracture. This is expecially true in low temperatures, where materials can become brittle. In fact, pellican cases have passed stringent military test to operate in temperaturs from sub-zero to 131 degrees farenheit!
Another strength about are the gradual defelector ribs. An impact force that hits these ribs is driven away from the case. These ribs protect the attachment points for the latches and hinges. Automatic Pressure Release Valve
You cannot change alittude with an airtight case and still open the lid. That's because air pressure is higher at low altitudes which creates a vacuum inside the case. To solve this, pelican originally created a purge valve that released pressure by turning. There are millions of pelican cases in use today with this origonal manual valve.
Today, pelican cases use an automatic purge valve. Pelican worked with gore-tex to develop a special membrane that allows air to move freely but is still waterproof. This works because water molocules are blocked, but allows air molocules, which are smaller, to move freely in and out of the case
