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.).
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 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.
Most Miscellaneous: Dynamic cows tails, decrocheurs, 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.
