The container is formed by three interlocking lengths of corrugated sheet steel, closed at each end by hexagonal sheet steel plates. The three interlocking lengths are held in position by four encircling sheet steel bands and buckles. The buckles are prevented from opening by two arming wires. To a hub on the exterior of the after end plate are attached three bungee cords 7 1/2 inches long, to each of which is attached a steel hook. Each hook fits into a hole in the side of each section of the container.
One of the three interlocking corrugated lengths serves as the upper portion of the horizontally suspended container. To this upper portion is spot welded a smooth semicircular sheet steel piece 31 1/2 inches long, in the center of which is located the suspension lug. On each side of the lug, between it and the inboard steel bands, there is welded an eyebolt to take the arming wires.
Fitted around the container there may be a safety device consisting of a canvas strap, a black powder burster charge in a small container, and a friction igniter with a 2-second delay. The igniter cord is attached to the arming wire and as the container leaves the plane the delay train is ignited. After 2 seconds, the strap is blown apart and the sections of the container fall free.
