Stuart91 Posted May 17, 2011 Share Posted May 17, 2011 I was tidying up a random box of hardware, and found this: http://i54.tinypic.com/2yvl4z4.jpg It's a double length coupler, which seems to be very handy for getting coupled lengths of scaff a bit more rigid. I've already put it into service at an installation and it's working well, so what I want to do now is pick up some more of them. I've googled my way round various suppliers of Kee Klamps etc. but every vendor I've found only does the standard couplers which are half the length. Flints don't appear to have any either. Wondering if anybody else knows of a source? Link to comment Share on other sites More sharing options...
themadhippy Posted May 17, 2011 Share Posted May 17, 2011 http://www.doughty-engineering.co.uk/cgi-bin/trolleyed_public.cgi?action=showprod_T25108 any good? Link to comment Share on other sites More sharing options...
madorangepanda Posted May 17, 2011 Share Posted May 17, 2011 As above, I've only ever seen them from Doughty/a Doughty distributor. If you want something more substantial use one of these. Available from plenty of suppliers. http://www.doughty-engineering.co.uk/cgi-bin/trolleyed_public.cgi?action=showprod_T25000 Link to comment Share on other sites More sharing options...
AndyJones Posted May 17, 2011 Share Posted May 17, 2011 If it's for a permanent install then I would probably be using an internal bar to do the joining, It's stronger,and means that you won't loose any space on the bar. Andy Jones Link to comment Share on other sites More sharing options...

Stuart91 Posted May 17, 2011 Author Share Posted May 17, 2011 http://www.doughty-engineering.co.uk/cgi-bin/trolleyed_public.cgi?action=showprod_T25108 any good? That's the one - well done. I hadn't thought of Doughty offhand. The internal joiners that I've used in the past seem to be OK but have a bit more "give" than I'd like, especially when there are longer spans in use. (i.e. the style pictured below - if there are others available that I'm not aware of, I'm all ears...) http://www.10outof10.co.uk/acatalog/t25100.jpg Flints SCF114? Thanks Brian - I had a Flints order going in this afternoon so have added a few of them onto it. Strangely, it wasn't listed under their "allen key clamps" catalogue heading which is probably why I was able to overlook it. Link to comment Share on other sites More sharing options...
the kid Posted May 17, 2011 Share Posted May 17, 2011 www.alvinkeyclamps.co.uk May well have them but not on the site. Link to comment Share on other sites More sharing options...
rgye Posted May 18, 2011 Share Posted May 18, 2011 The internal fitting as illustrated in Stuart's last post is really not intended for horizontal bars: they are designed for vertical tubes where the two pieces are in compression. For horizontal bars you should always use a fitting with a more positive grip like the one shown in his original post. Link to comment Share on other sites More sharing options...
AndyJones Posted May 18, 2011 Share Posted May 18, 2011 Or a solid bar drilled through and held with bolts and nyloc nuts. Link to comment Share on other sites More sharing options...
