FLANGE BACK
The rear of the frame has a machined flange that is fixed on to a flanged wall thimble. The thimble is grouted into the wall and there is a seal provided between the wall thimble flange and Penstock flange. The wedging devise on all the 4 sides (bottom side excluded when it is flush invert type) are adjustable. Sometime due to space constraints or for reasons of economy, the wall thimble is eliminated and the flange of penstock is held on to the wall by anchor bolts.
