so we wonder the solution to a common problem here we've got complex set of solid joints and we want to reach solder one of these fittings which if there's a leak a standard traditional heat map wouldn't have the hole in the center so that would be fine for an application like this down here where you can rest it against the floor you can get them through work wait on a solder joint but when you are doing here this whip off the floor what would normally happen is you'd have to hold your traditional marketplace because if you let it go it falls away there's nowhere to prop it you look at the pipe clips here and you prop it but it's too small you're not a big enough area that's why the Oh Matt was designed this hole in the center and the split allows you to place that over the pipe pull it back through again and then move back into place there and freeze your hands off then to do the sole grip so again the solder joint could be here when you solder in flux but you've got both hands-free using the opah so as we've shown you the OMAP unfortunately this size no Matt is actually no good for this restricted area pipe clips here what you don't want to do is mess about removing all of that but you need to resolder all you've moved this joint here so specifically for this job we have the small 16 Joe Matt that was a simple slide that between the two pipes move the flat behind the back engage and you've then got access to all three joints on that team ever since the way you go it's a lot behind the back so you won't mark the clients wall and then you do the small a map mini coma you
