Tuffpak tripod case comes with 2" of foam in lid and base to protect your valuable equipment. Model number of each case will indicate its size. The first 2 numbers represent diameter of case at its smallest point (where handles are). Since case is polygon, there may be areas that are larger. The second 2 numbers in model number represent the minimum length (in inches) of tripod you'll want to put in case. Since lid is held in place with an adjustable strap, you can secure lid with tripod roughly 5 inches longer than length indicated by model number.
The foam in lid is glued in place. The foam in the base (which is protected from feet of your tripod by circular plastic disk) is held in place by detents which have been molded into base of each case.
Key locks can be added as an accessory.
The rotational molding process used to form every Tuffpak™ enables us to produce an extremely durable lightweight case that can withstand even roughest baggage handlers for lifetime. Well, some products you've probably seen include, gas cans, big yellow crash barrels found on most of our nations freeways, water tanks, toys, dumpster lids and many other items where durability is mandatory.
As a direct result of this unique molding process, every corner in Tuffpak™ has 20% more material than sidewalls. All of this yields case so "tuff" that Nalpak stands behind every one of them with their "Guaranteed For Life" guarantee.
Tuffpak™ is resistant to jet fuel, solvents, moisture, dents, abrasions, shock, cold to -40° F and heat to +140° F.
Some Tuffpak™ models come equipped with wheels which are permanently attached and protected by "fenders" that are molded into bottom of case. No need to remove them (and possibly lose them) or find place for them in your other bags. The wheels along with pull handle on lid make it snap to move even heavy load.
