More About Ascender Handles

 

Handle templateThe U.I.A.A. once set a standard defining a minimum acceptable size for an ascender's handle. The standard included a minimum hand opening size defined by the area obtained by drawing a 20 mm. radius top circle and a 15 mm. radius bottom circle whose centers are 60 mm. apart, and then connecting the circles with the common tangents as shown in the figure. I prefer to think in terms of the overall length of the opening and the diameters of the circles, so I'll refer to this as the 95-40-30 shape.

I can't take this standard very seriously, for some of the following rather obvious reasons:

Nevertheless, I thought it might be amusing to define a few other shapes and compare the various ascenders. I made six different "handle size gages" out of wood, and used them to test the opening for each handled ascender in my collection. All of these were designed by connecting the tangents of two circles in the same manner as the U.I.A.A. defined their handle standard. In addition to the U.I.A.A. gage, I made the following gages:

 Code  Size What fits
 60-20-20 Tiny Two or three of my fingertips
 80-30-30 Small Three of my fingers, fully inserted
 100-30-30 Ample Four of my fingers, fully inserted to palm
 110-35-30 Large Four of my fingers, wearing leather gloves, fully inserted
 120-50-40 Huge! Four of my fingers, wearing expedition mittens, not badly compressed.

Needless to say, these sizes are completely arbitrary, and I don't believe that I can justify this as being a very good set. "near misses." Second, since none of the ascenders accommodated the 120-50-40 gage, it was clearly too large to be meaningful. In 2015 I made four more gages with intermediate sizes, but one of these, the 115-40-35, was still too large for any of my ascenders to accommodate it. Some of the gages are tapered (the circle at one end is larger than the other), and these columns in the table are shaded.

Now for the results. A green dot Fits indicates a fit with no problems, while half a dot One Side indicates a fit on only one side of a dual-handled ascender. A yellow dot Odd fit indicates that the gage only fit in an unusual way, such as in a particular ascender configuration not normally used for ascending (e.g., if the cam safety was not in the locked position). A green dot with an orange bar Barely fits indicates that the gage barely fit, while gray dot Barely misses indicates that the gage barely missed fitting. I used the No fit symbol to emphasize a no-fit situation that some people might find surprising, just to show that I didn't omit a green dot by accident.

In the ID column and chart, I used a red background for cast-frame ascenders, green for milled-frame ascenders, and blue for stamped-frame ascenders. Magenta indicates a two-rope ascender.
