Kerfed – A frame specifically designed to expand in width for various wall thicknesses formed with a kerf to install kerf applied Q-Lon gasket. Kerf RediFlex series frame has a single door section and 6 closure sections to fit walls from 4″ to 12 1/2″. This type of frame can arrive at the jobsite pre-hung with jamb, door, hinges and weatherstrip.
• Hinge Backset – refers to the measurement from the edge of the hinge leaf to the face of the door closest to the frame stop when the door is closed
• Lock Backset – refers to the measurement from the latch edge of the door to the centerline of the cylinder or handle of the lockset or latchset
• Exit Device Backset – refers to the measurement from the latch edge of the door to the centerline of the active case of an exit device. The backset of a vertical rod exit device determines the location of the strike.
preparation on the frame. In some cases, the latch may not line up with the center of the operating hardware shown on the exit device template
• Flush Bolt Backset – refers to the measurement from the meeting edge of the inactive door to the centerline of the flush bolt. Strike preparation in the header is based on flush bolt backset plus 1/8″ from centerline between the two doors of the pair
Frame – Cross section drawings of frames and casings applied to a wall with all critical dimensions shown.
Plan – Cross section drawings of wall conditions and frame types shown on the construction plans. Plan details do not necessarily have all the critical dimensions shown and may be typical for different wall types and conditions.
• Rim – Surface mounted on a single door or active door of a pair with the latching mechanism at the same height as the device and the strike is on the stop of the frame instead of the rabbet
• Rim Vertical Rod (SVR)– Surface mounted on one or both leaves of a pair of doors with latching mechanism at the head and floor. The strike is mounted on the stop of the frame instead of the rabbet. In some cases, the bottom rod latching mechanism is omitted (LBR- Less Bottom Rod)
• Mortise – mortised into the edge of a single door or active door of a pair using a traditional latch bolt in a strike plate on the frame rabbet
• Mortise Vertical Rod (CVR) – mortised into the edge of one or both doors of a pair concealing the latching mechanism. The strike is mortised into the frame rabbet at the header
• Smoke Gasket – used to prevent smoke from traveling through an opening allowing building egress in case of fire
• Weatherstrip – used to prevent water and air from penetrating an opening saving energy cost.
• Sound Seal – used to greatly reduce noise levels from one side of an opening to another. The amount of reduction in noise is measured and rated as the STC (Sound Transmission Coefficient) of an opening
A door with a four-sided frame installed above the finish floor that provides occasional access to a closet, storage compartment or mechanical space.
