Neighbouring component compatibility

Neighbouring component compatibility is something we have spoken about a lot over the years, meaning that one does not only consider whether the components are well configured and compatible, but also giving thought to whether the neighbouring components work well together.

Thinking of this and flicking through my photo library, a number of examples occurred to me where this was obviously not the case.

Without further ado, I give you…

Steel cables, winches and Hitch Climber pulleys? Never a good combination. Or any pulley you intend to use with synthetic lines again… quarantined this one during gear inspection during a climbig course.

Wrong shape carabiner connected into a pulley: This is what happens when you snatch the whole top of a tree onto a Pinto pulley attached with a modified d-shape connector, causing an inequal load on the two sides of the Pinto… not to mention the overload.

This is not really neighbouring components, but also not a good idea: long-term exposure of aluminium to salt water causing corrosion. This connector was left in sea water for a long time, admittedly, but the delamitation caused by the corrosion is very interesting, so I thought it was worth sharing. This is a phenomenon you will sometimes see on buckles and other metal components used in hot and humid environments…

And one final example, going out on a bang, so to say: do not set-up your pool on your balcony. A large, inflatable, water-filled structure combined with a large, rather flimsy wooden structure = baaaaad compatibility of neighbouring components… QED.
