A blow-molded plastic female interconnection system has a receiving section and a locking section. The receiving section receives a male interconnect. The receiving section has a floor aperture shaped to allow the corresponding male interconnect be pushed into the locking section. The floor aperture can have various shapes depending on the shape of the male interconnect. Within the receiving section is a locking projection on the receiving section's back wall and the locking projection has a bottom section that defines a portion of the ceiling of the locking section which has no back wall. When the male interconnect is being pushed into the locking section, the locking projection deforms due to the locking sections no back wall. When the male interconnect is below the locking projection, the locking projection bottom section is positioned on the male interconnect to securely interconnect the male and female units.

An A-frame ladder has a first ladder and a second ladder. The first ladder has two rails interconnected by a plurality of steps and a first set of grooves that receive a gate/barrier device to inhibit a person from using the first ladder's steps. The second ladder also has two rails interconnected by a plurality of steps and a second set of grooves, interconnected to the first set of grooves, that receive the gate/barrier device so the first ladder and the second ladder can be used and inhibits a person from entering the area between the first ladder and the second ladder through the second ladder's steps.

An A-frame ladder has a first ladder and a second ladder. The first ladder has two rails interconnected by a plurality of steps and a first set of grooves that receive a tambour device that inhibits a person from using the first ladder's steps. The second ladder has two rails interconnected by a plurality of steps and a second set of grooves, interconnected to the first set of grooves, that receive the tambour device so the first ladder and the second ladder can be used and inhibits a person from entering the area between the first ladder and the second ladder through the second ladder's steps.
