Clamps

Recommended Posts

Bit of an unusual one, does anyone know of a source for a double in-line clamp, or back to back clamp depending on your terminology.

 

I want to be able to clamp a lightweight pole vertically to either a horizontal bar, or a solid surface such as a table top.Like this.

Most of the double clamps I have found, are orientated incorrectly for this, as they are attached side to side, or 90 degrees out of alignment.

 

I have found this, it is orientated correctly, but looks a bit light weight.

Ideally something like 2 of these fixed back to back with a lockable swivel would be ideal, but I havent found anything like that yet.

Any ideas appreciated. Thanks.

Superclamps wont work, as the clamp bolts are on the rear face, therefore preventing them from being mounted back to back. The clamping mechanism has to be on the side of the clamp to allow back to back mounting.

Here are some ideas - Its hard to be sure as I don't know what scale of edifice you are constructing - as ever if you want a signed off structural for life critical go and pay someone fancy, I am just a UniLife bodger bloke you met on the net

 

If the small pole can be scaff (48mm) then try girder clamps

If the small pole can be M12 studding then

Various sizes half clamps

If you must go smaller your "ideal " second picture is a CLIMPEX laboratory clamp

there are swivel and ball joint types and I suspect a flat to pole swivel or ball - it fits Lab size about 22mm

Have lots of fun but don't come crying if you break the rainbow!

do PM if I can complicate your project any more

This is called a "transom coupler" in polite society and will crunch into a 2x2 nicely.

 

Real scaffolders call the minge clips and they seem to be less than commonplace these days. Not sure if it suits but there are umpteen Kee clamps and scaff clips that can be adapted with judicious use of a hacksaw. Swivel clamps were my favourite bodges.

Maybe a pair of either of these with a short hex-bar to join them?

I think Cirro are UK dealers (I'm sure there are others) but I hope your pockets are deep :-)
