HANDING CHART

Changing Handing for the Mortise Case
The handing of an ABH 6600/LR6600 Series mortise case can be changed without opening the case. To change the hand, you need to rotate the latch bolt. For all lock functions except W and N, you also need to adjust the hub toggle positions. No steps are required for adjusting the bevel since the armored front on the mortise case automatically adjusts to the bevel of the door when the case is installed.

To Rotate the Latchbolt:

1. Confirm that you need to rotate the latch bolt to match the handling of the door.
   NOTE: the angled surface of the latch bolt must contact the strike when the door closes

2. To rotate the latch bolt, insert a flat blade screwdriver into the latch access point approximately 1/2″ into the case and press to extend the latch out of the case.

3. Rotate the latch bolt 180 degrees and allow it to retract.
   To Change the Position of the Hub Toggles:

4. Refer to the table below and determine the proper position for the hub toggles.
   FUNCTION| HUB TOGGLE POSITION
   ---|---
   6632, 6637, 6638, 6645, 6653, 6656, 6654, 6657
   & 6658| Inside Down (always unlocked) & Outside Up (lockable)
   6641| Both Up
   6610| Both Down

NOTE: For LH and LHRB doors, the inside os the back side of the mortise case, and the outside is the cover side of the case. For RH and RHRB doors, the inside is
the cover of the case and the outside is the backside of the case.

5. To change the position of a hub toggle, remove the toggle screw, move the toggle into the desired position, and re-tighten the screw.
