The dual magazine pouches allows one of the two magazines to be partially ejected from the pouch automatically when the pouch is opened so that a shooter has quick and easy access to the magazine yet the remaining magazine is retained securely within the pouch. The pouches include a main body formed by a cargo pocket sewn to a back/flap, which extends above the cargo pocket and folds over to enclose the open mouth of the pouch, and an “elevator” mechanism, which automatically raises one of the magazine when the pouch is opened. The “elevator” mechanism is provided by two elastic members: an elastic retention band and an elastic “elevator” band or cord. The retention band snugly holds a first ammunition magazine against the back/flap when fully inserted into the pouch. The elevator band forms a “saddle” within which a second ammunition magazine sits. Fully inserting the second magazine stretches the elevator band. When both ammunition magazines are fully inserted into the pouch, the back/flap is folded over the tops of the magazines and secured by hook and loop patches. When the back/flap is lifted, the tension from the elevator band automatically lifts the second magazine partially ejecting it from the pouch above the exposed top of the first magazine.

A threaded rod hanger has quick lock plunger mechanism that includes plunger pieces within a tapered bore in a housing. The plunger pieces have tapered outer surfaces.
