Hey TS'ers is anyone still making these. A friend of mine lost his. Thanks
Ted's GAKbrella's use a 3/8" - 16 thread with option to add a US standard mic thread adapter for use with a windtech clamp but I think he's run out of stock for this year.
Don't know of any 1/4" thread umbrellas but it seems that 1/4" mount wouldn't be able to handle wind loads very well.
