The Von Duprin 22, 33, And 99 Dogging Shaft 090040 is the peice that the hex dogging key would fit into. The shaft is for a 5/32" dog key, but it has to be the long version. The shorter versions will not have enough reach to get all the way into the shaft. This is a very common problem area, the hole that the key fits in is only about 1/4" deep, and if you do not push down on the hex key when locking it open it will round out over time. To remove the shaft, just pull it straight out with a part of channel locks. We reinstalling the new one you might have to bend the ends of the adapter spring 090042 back down. This dogging shaft is for use on all Von Duprin Panic Exit Devices shipped after 1997.
