Material seems to be the same as others use. I can't see the drawings too well but assume they are OK. Architectural loads are presumably similar to standing rigging ones.
"These are an excellent alternative to swaging. They are fully self assembled (Using a Spanner) for fast, secured, highly corrosive and professional finish"
????
I like the idea and simplicity but somehow 'feel' that the traditional fitting where you part and separate the strands over the cone would grip the wire better ??
This is intuition and I would like to shown to be wrong ( so I can use these!!)
All that a swage does is compress a piece of steel tube over the wire, these achieve exactly the same thing by compressing a split collet over the wire and there is no reason for it to be any less secure than the fiddly type where a cone is inserted between the core wires and the outer ones. That type relies on the ends of the outer wires being bent over the end of the cone. The only way to be sure that they are assembled correctly is to undo them and look. The simpler assembly method of these should be foolproof.
yes I appreciate the similarities to how a swaged fitting works but have nothing to tell me if compression with a spanner will equal that achieved in a swaging press.
I doubt that a swaging machine will achieve much more than a spanner used to force a slightly conical collet into a matching hole, as the mechanical advantage is huge, and provided the collet and the nut are accurately made (probably CNC machined) the pull out force will probably exceed the safe working load limit of the wire. Blue Wave swageless terminals also use a collet which fits over the wire. http://bluewave.dk/technical-info-2/swage-and-swageless-fittings/
Well, ones like Norseman and Stayloc do OK with spanners? So why not these? The legal responabilites for the arquitechtural lot are just as tough as for marine, likely more so.
