Reprinted from a Pelican press release:
To meet the demand for long, deep and versatile shipping cases, Pelican Products, Inc., has introduced the 1740 and 1770 Long Cases.
For easy one-person transport, the 1740 comes standard with several mobile-friendly features including two rugged double-wide handles for easy steering and team lifting. Wide-track, polyurethane wheels (for stable mobility) with ball bearings and nylon hubs ensure extended towing durability. Designed to either be moved manually or stacked on pallets, the 1740 features four extra-deep base-to-lid locking cleats that ensure maximum stacking stability.
Built for longer equipment and weapons such as .50 caliber guns and survey drill kits, the 1770 Long Case is Pelicans longest case to date with a length of 54.58. It features the same transit friendly attributes as the 1740.
With more than 6,600 (1740) and 7,300 (1770) cubic inches of usable storage space and an infinite number of internal storage possibilities, both cases feature an open cell core, polymer wall construction engineered to protect sensitive equipment from some of the harshest conditions on Earth.
Additional standard features include a lid equipped with a polymer o-ring for a dust and water tight seal and six dual action latches that have been tested to withstand nearly 400 pounds of pulling force (but open with a light pull). Genuine Pelican Protector Cases can always be spotted by their distinctive, trademarked Dual Band design.
Due to their large internal volumes both cases feature dual integrated automatic pressure equalization valves that keep moisture out and prevent vacuum lock so theyre easy to open at any altitude.
