• Measuring Offsets: The offset of a surfacemount latch is the distance between the surface on which you mount the strike (the jamb) and the surface on which you mount the latch (the door).  Figures 1 & 2 
• Straight or Offset Handle: Figure 3 illustrates a straight handle edge mount latch.  Figure 4 illustrates an offset handle, which is bent away from the latch body to allow more room for grasping the handle. 
• Edgemount Latch: Mounts to the edge of the door.  Edgemount latches are most commonly found on lightweight reach-in doors, under counter, and back bar units. 
• Surfacemount Latch: Mounts on the face of the door.  All walk-in doors use surfacemount hardware. 
• Safety Latch: A walk-in latch that uses a push-rod to prevent accidental entrapment – even if the latch has been locked from the outside.  In many states, including California, safety latches are required by law on all walk-in units. 

HINGES:

• Cam-Lift Hinges - These gently rise as the door is opened, permitting the weight of the door to assist in the closing action.  To determine if a door is hinged left or right, face the cabinet from the outside.  If the hinges are on the right, the door is considered hinged right.  All of the hinges in this catalog are reversible unless otherwise noted.  A reversible hinge will work on either hinged right or left hand doors.
• Measuring Offsets - The offset of a surfacemount hinge is the distance between the surface on which you mount the butt (the jamb) and the surface on which you mount the blade (the door) as shown in figure 2.
• Spring Assisted Hinge - A cam-left hinge enhanced by a spring for a more positive closing action.
