Miscellaneous Devices

There are a number of interesting devices that I've collected over the years. There is no real pattern to what I've collected: all of this is peripheral to my main interest in ascenders and descenders. Briefly, the categories are as follows:

Anchor Brakes (a.k.a. Dissipators)
Shock absorbers for climbing anchors that have metal parts (i.e., you won't find the Yates Screamer here).
Brake Tubes
Lowering spools for rescue use.
Chest Boxes
Single roller chest boxes for rope walker systems (etc.), and double-channel boxed for Mitchell Systems (etc.).
Dynamic Cow's Tails
Dynamic cow's tails incorporate a shock absorber of some form so that the forces generated in anchored falls (such as on via ferrata) are reduced to within human tolerance.
Flipline Adjusters
Flipline adjusters are arborist tools, some of which function much like ascenders and could probably be used as such.
Grappling Hooks
Don't trust your life to a grappling hook!
Hauling Pulleys
I don't collect basic pulleys, but I have a few hauling pulleys that have integral cams. Some of these are for rescue use, others are for "more productive" uses like big wall climbing.
Rappel Safeties
Safety devices for people that don't trust their own abilities.
Rope Grabs
Industrial safety devices that often look like ascenders, but are usually far too heavy for that. Some ascenders are used as industrial rope grabs; these are listed in the ascender section. I decided to place the rope grabs into the following three types:
Most Miscellaneous
Dynamic cows tails, décrocheurs, grappling hooks, and other things that don't even fit in as normal miscellanea.

A word on the tables…

The tables include some numerical data:

 ID  This is just my catalog number so that I can keep these straight
 Weight  Weights are in grams. Webbing, slings, etc. are not included.
 Height, Width, Thickness  I've given the dimensions in millimeters. The measurements are in perpendicular directions. I've chosen to measure the maximum dimensions instead of the most obvious dimensions. Sometimes this leads to numbers that are more than what you would expect - for example, the thickness of a bent plate would be more than the thickness of the unbent plate.
Standard Volume   The standard volume is just the product of the height, width, and thickness divided by 1000. This gives a volume in milliliters of a box that the device will fit into. Odd shaped devices are penalized by this formula, but since they are generally harder to pack, this number might be useful.
