A door jamb is the vertical section of a door frame, which acts as a support for the remainder of the frame, as well as the door itself. Each frame has two jambs. The hinge jamb is the side where the hinges are installed, and the strike jamb is the side where the locking mechanism latches into the strike. The jambs are also used to mount the frame to the surrounding wall. The horizontal member that connects the two jambs is called the head.

The material used to make a door jamb is largely determined by where it will be used. In most residential settings, the door frame is made of wood. It is typically hidden by casing or trim, so the type and finish of the wood. It is typically hidden by casing or trim, so the type and finish of the wood is generally not important. For commercial uses, hollow metal door jambs are most common, and are made of cold-rolled steel for interior applications, or galvanized steel for exterior use. Some architects may specify frames made of stainless steel or aluminum to provide a nicer finish, while fiberglass frames are used for their durability and weather-resistance.

It is quite a challenge to cut the undercut door jambs flush or along the walls when installing carpet or tile.

That is exactly why the Dimar Door Jamb Blade will save you time by doing “hot cuts” on the job.
