Dive Rite Transpac Manual - Simply Scuba

Transpac II Owner’s Manual Page 26Figure 21: Compact double cylinders.Here the manifold and tank boot hold the cylinders together as a single unit. Youcan treat such cylinders as though they were a large single tank, and attach themto your Transpac II with cam straps. If the standard Transpac II cam straps are notlong enough, you can replace them with Model 2032D straps, which accommodatea wide variety of double cylinders.To attach higher capacity double cylinders to your Transpac II, the doublesmust be bolted together with Dive Rite 1033 or 1033W tank bands, or theirequivalent. The bands should be spaced so that the bolt centers are exactly 11.0inches/28cm apart. Doubles used with Dive Rite “Wings” BCDs and traditionalback plates are already set up this way.Figure 22: Bolt clearance.As shown in Figure 22, the bolts should protrude quite a distance from the center ofthe bands—but not so far, however, that they will gouge the wearer in the back.Figure 23 shows how to attach double cylinders, air cells and harnesses to oneanother using 2084 stabilizing plates. (To access the harness bolt holes, you willneed to temporarily pull the back pad/lumbar support away from the inside of theharness.) As with single cylinders, the air cell is sandwiched between the cylindersand harness.
