Updated Questions and Verified 100% Solutions (2026/2027)
Grade: A+|Status: Guaranteed Pass
Anti-Rack Device - Answers -Hardware normally attached to doors to provide additional strength
and stiffness to the door and end frame assembly. Such a device allows containers to withstand
greater transverse twisting (racking) forces
Bend - Answers -A deflection in a structural component which causes the component to change
direction from that of its original design
Blade - Answers -Hinge component permanently attached by welding or bolting to the door
Bottom Frame - Answers -The lower structural support for the floor, panels and posts
Bottom Side Rail - Answers -A structural component running longitudinally along the bottom
sides of a container between the end frames
Bow - Answers -A gradual (not abrupt) deformation of the entire length of the component in a
direction perpendicular to the length
Broken - Answers -Fractured or shattered into two or more separate pieces

,Bushing - Answers -A tubular enclosure surrounding a rotating shaft which reduces friction
against rotation, and may reduce electrolytic corrosion
Caulking (Sealant) - Answers -Material used to seal all joints and riveted seams to ensure
watertightness. Caulking is used between wood flooring and board edges, sides and end frame
assembly
Center Rail - Answers -A steel section, found in many containers with plywood panel flooring,
running along the center of the container from the rear sill to the front sill (or to the tunnel
bolster) and separating the plywood panels along the longitudinal center line. This component
often has a "hat-shaped" section, but a flat bar may also be used in some cases for the same
center rail function
Chassis - Answers -A vehicle built specifically for the purpose of transporting a container, so that
when the chassis and container are assembled, the unit produced serves the same function as a
road trailer
Consolidated Date Plate - Answers -A single rectangular marking pate affixed to the door which
containers certification information applicable to more than one convention, regulation or other
certification
Container - Answers -A rectangular structure of standardized dimensions, designed to carry unit
loads, packages or bulk cargo, and which is quickly transferable as a complete module between

,a number of modes of transportation. (Unless otherwise stated, this manual refers to "dry-van"
or closed containers, whose cargo space is enclosed and weathertight when the container is
carrying cargo.)
Corner fitting (Corner casting) - Answers -A steel component located at each of the container's
eight corners (top and bottom) and welded to corner post and rail. The corner fitting (or corner
casting) has apertures allowing the container to be handled, stacked and secured.
Corner protection plate (corner gusset) - Answers -An additional plate attached to the container
roof, adjacent to the top corner fittings, providing protection from misuse of spreader
equipment.
Cracked - Answers -Having a break which penetrates the entire thickness of material and causes
it to split slightly. In addition, if a weld between two panels or two different metal components
has any break in it, even if the entire thickness of the weld material is not penetrated, that weld
is considered "cracked".
Crossmember - Answers -A transverse component, other than a sill, tunnel bolster or forklift
pocket, attached to the bottom side rails and supporting the floor
CSC (International Convention for Safe Containers, 1972) - Answers -An international treaty
which entered into force on September 6, 1977, requiring safety approval of all containers, the
affixing of a safety approval plate ("CSC plate"), inspection at intervals thereafter, and
maintenance in safe condition. The CSC is administered by individual governments with the
advice of the International Maritime Organization (IMP), a branch of the United Nations.

, Cubic Capacity (Cube) - Answers -Useable internal load-carrying space within a container,
expressed in cubic feet, cubic meters (m3), gallons or liters. Also called "available cube" or
simply "cube".
Customs Plate - Answers -A marking plate permanently affixed to the container which indicates
compliance with the Customs Convention on Containers
Customs Seal` - Answers -A temporary device fitted to the container that prevents the container
from being opened without detection
Decal - Answers -A self-adhesive, non-metallic marking permanently attached to the container
Dent - Answers -A localized depression in a panel or structural member made by pressure or an
impact or blow that causes an abrupt change in the shape of a component over a limited area
of the component
Door Gasket (door seal) - Answers -A piece of rubber or other flexible material attached to the
door edges in order to provide a waterproof seal between the door and the end frame of the
container.
