INSTALLATION INSTRUCTIONS:
1. Door to be machined for standard 161 prep.
2. Install latch (Item 1) using either #8 x ¾” FHWS (Item 2) or (2) 8-32 FHMS (Item 3) depending on door 
material type.
3. Take pull side handle assembly (Item 4) and rotate cam pin as shown in Detail “A” above.  Place pull side 
handle assembly (Item 4) on pull side of door and slide the cam shaft through the latch cam on the latch.  
4. On the push side of the door, assemble the push side adapter plate (Item 5) to the sex blots on the pull side 
handle assembly using (2) 10-32 x ¾” FHMS (Item 6).  Test pull handle for free movement of the latch bolt 
before installing push side handle assembly.  If latch bolt does not extend or retract freely because of any 
type of binding, loosen screws (Item 6) to align adjustment of base assemblies and retighten screws one at a 
time while checking for proper latch retraction.  
5. Take push side handle assembly (Item 7) and rotate cam pin as shown in Detail “A” above.  Assemble the 
push handle assembly (Item 7) onto the push side adapter plate (Item 5) using (4) #10 star washers (Item 8) 
and (4) 10-32 x ¼” Truss Head MS (Item 9) and engage push cam onto the pull side cam shaft.  
6. Test both handles for free movement of the latch bolt before tightening all screws.  If latch bolt does not 
extend or retract freely because of any type of binding, loosen screws (Item 6) to align adjustment of base 
assemblies and retighten screws one at a time while checking for proper latch retraction.  
7. To prevent the handle assemblies from possible twisting, which in turn can cause binding, determine which 
staking screw hole will be used for the push and the pull side handle assemblies (the staking screw installs on 
the staking screw hole location opposite the direction the handle is mounted).  Depending on door material, 
prep for (1) staking screw on each side by either spotting for #10 wood screws (Item 11) or drill and tap for 
12-24 machine screws (Item 12).  
8. Install covers (Item 10) using (2) 8-32 x 3/8” FHMS (Item 3).
