3/8" sliding t-handle...longer than 8"?

[Steiger9]

Im on a quest to find something to drive my tap holders. I've been through all the past posts on ratcheting t-handles and have gotten some good ideas, but the few options I like would have to come from the UK it seems. So if I settle for a non-ratcheting t-handle I'd want it to be bigger than the one I've got. But it seems ALL sliding thandles in 3/8" drive are 8". Unless you folks know of some obscure brand that makes a longer one?

I believe Capri Tools and Teng tools both offer a 3/8 drive adapter that can be slid on any length extension making it a tee handle.

Could use a 1/2" drive with a 3/8" - 1/2" adapter.
