INSTALLED IN A NON-KERFED JAMB
Exterior weatherstripping is the type of weatherstripping primarily used on commercial metal jambs. The diagram above shows how the exterior weatherstripping’s rubber gasket is compressed by the surface of the door to create a seal. Though used primarily in commercial applications, this type of weatherstripping may be appropriate for use with wooden residential jambs when the jamb or door is worn in such as way as to prevent the copper or prefabricated weatherstrip-ping typically used with in the unit from creating a satisfactory seal.

Drags and drip-drags are another type of exterior weatherstripping used in residential applications. They are applied to the bottom edge of the exterior surface of an out-swinging door, as shown in the diagrams above, and perform the same basic function of door-bottom weatherstripping; i.e. they prevent water from coming in under the door. The rubber drag portion of these devices works with the rubber bulb of an out-swing threshold creating the outer barrier of a two part seal. The drip-drag is intended to be used in applications where the door receives more direct exposure to rain or other sources of moisture. The metal portion of the drip-drag is called a drip cap and may be used without the drag to help deflect water away from the bottom exposed doors that are either in or out-swing.
