Polished chrome extendable pole used to turn the screwjack winder, finished with solid wood handles.

Your crank handle will arrive compressed to its shortest length of 870mm.
To extend the length to the size you require simply unscrew the two brass knurled nuts halfway down the brass tube and remove the threaded screw.
Now pull the hook end out from the handle end, as you do this you will see that the inner tube (hook end) has various holes down its length.
Get the crank to the length you require and then line up the inner holes with the holes in the outer tube and refit the screw and knurled brass nuts.
