[ Top | 5-bar | Return to Racks ]
I acquired my 4-bar from Petrenko World in 2007.
The frame is 7.9 mm. steel with 26 mm. internal spacing between the two legs. The first and third bars are 50 mm. long and made from 18 mm. o.d., 4.1 mm. steel tubing. They do not open. The second bar is 50 mm long with an 18 mm. diameter. It has the end cut away so that it opens freely (i.e., no "click" closure). The bottom bar is an inverted 70 by 18 mm. hyperbar; like the third bar, it opens freely. Each leg of the frame has a hex nut backed by a nylon lock nut. The threads protruding above the lock nut are covered by plastic tubing. A steel sleeve pressed onto the frame near the U-bend keeps the bars from moving two far downward.
All steel parts except the nuts have a black okide finish.
There are no markings on this rack.
The steel bars make this a rather heavy rack for its size.
[ Top | 4-bar | Return to Racks ]
I acquired my 4-bar from Petrenko World in 2007.
The 5-bar uses the same frame and bars as the 4-bar, but adds a fifth bar at the top, so that the first and third bars are solid, pivoting bars, while the second and fourth are solid. All steel parts except the nuts are zinc plated.
Having the odd-numbered bars pivot on a U-frame rack is an unusual choice, but it works.
The 4- and -5 bar racks are each available in either oxide finish or zinc plating.
