1-1/2" Offset – Suffix 1-1/2
Offset is the distance from the face of the door to the pivot
point. Extended offsets should not be used unless there is
cladding on the face of the door or there is trim to clear
on the frame. 1-1/2" offset arms and pivots are for doors with
cladding or trim that project 3/4" from the face of the door.
