Technical Details

I acquired this rack from Howell-N-Mann in 1993.

My Howell-N-Mann Twin rack is 416 mm. tall, 166 mm. wide, 20 mm. thick, and weighs 830 g. The frame is made from 9.5 mm. ASTM grade 6 6Al/4V titanium alloy bent into shape. The bar channel internal widths are 20 mm., and the central channel's is 39 mm. There is one large (167 mm. long) common hyperbar at the top, and five smaller ( 52 mm. long) standard bars on each side. All eleven bars are 19 mm. in diameter. The bars are titanium tubing (same type as the frame) with hollow aluminum inserts to absorb and dissipate heat. Note the dimples in the bars - these help hold the aluminum inserts in place. Allowing 45 mm. for the rope leaves 116 mm. for spreading the bars.

There are no markings on this rack.


The twin is an experimental rack that Larry Howell designed for controlling two ropes simultaneously in a rescue situation. As far as I know, Larry only made two of these - this one (the second) at my request.

Larry jokes that this rack is designed to fry hamburgers, but I wouldn't recommend doing that if you intend to rappel on it afterward.
