Rough opening width is 1 1/4″ over nominal door width. This provides for 5/8″ clearance between the jamb and the wall. This clearance is necessary for the pocket on the strike and the projection of the hinge screws. Frames can be installed with smaller opening widths but, in some cases, the framing must be relieved to provide the necessary clearance for plumbing the frame and installing the hardware. Opening width maximum is 1 7/8″ which allows 5/16″ of the frame face against the wall. For wider rough openings, the frame must be positioned with equal clearance on both sides. (Use oval alignment slots to adjust clearance when installing)

Rough Opening height must provide clearance to level the header and interlock the jambs. Uneven floors will affect this measurement. Maximum space for adequate anchorage is 1 3/16″ over net height resulting in approximately 5/16″ of the frame face against the wall. While this is not recommended, the frame can still be installed.

For a pair of doors, the rough opening width is 1 1/4″ larger than the total nominal width of the doors plus the width of any astragal mounted between the doors.

For a pair of doors, the rough opening height is 1″ over nominal height or 13/16″ over net height. Since Timely standard frames are actually 3/16″ longer than the nominal height (Timely 7’0″ frames are actually 7’0 3/16″ long).

For a pair of Double egress doors, the rough opening width is 2 1/2″ larger than the total nominal width of the doors. Since the doors mount on the “stop” area rather than the “rabbet”, the frame is actually 1 1/4″ wider than a standard pair frame.

For Borrowed lights, the rough opening width is 1 1/4″ larger than the inside glass area, including any mullions. For stepped borrowed lights, the dimension is calculated separately for each step width.

For Borrowed lights, the rough opening height is 1 1/4″ larger than the inside glass area, including any mullions. For stepped borrowed lights, the dimension is calculated separately for each step width.

Opening width area will vary if using a partial height or stepped sidelight. The opening dimension is calculated separately for each “step” in the sidelight.

Opening height equals the net door height. For frames with stepped or partial height sidelights, the light area height is calculated differently than the door area. Measurement is based on calculating the rough opening for the door area first, then measuring from the top down on the sidelight area.

For a pair of doors, the rough opening height is 1″ over nominal height or 13/16″ over net height for the door area. Since Timely standard frames are actually 3/16″ longer than the nominal height (Timely 7’0″ frames are actually 7’0 3/16″ long). For the glazed area, the rough opening is 1 1/4″ over the total glass height plus 2″ for each horizontal mullion.

For standard frame with transom and no sidelights, opening width is same as for a three sided frame. Opening width area will vary if using a partial height or stepped sidelight. The opening dimension is calculated separately for each “step” in the sidelight.

Opening height includes the net door height plus the transom mullion(s) and glass area(s). For frames with stepped or partial height sidelights, the light area height is calculated differently than the door area. Measurement is based on calculating the rough opening for the door area first, then measuring from the top down on the sidelight area.

The rough opening for pocket doors is actually created by the pocket frame system used. The Timely P series trim kit is designed to fit most common applications. In some cases, wood pocket frames are used that include a 3/4″ strike jamb piece the full width of the wall. Since the Timely pocket trim kit is designed to replace this component, there will be a conflict when using this type of frame. Instead of recommending a rough opening size, we give guidelines that will accommodate standard sizes of trim kits.

HEIGHT

We provide our standard height frame which is 3/16″ longer than the nominal door height. In most cases, a full height door panel is used since the top of the door is mounted above the header trim piece. The rough opening height is determined by the pocket frame and the door height can be adjusted or, if necessary, the door can be cut to clear flooring material.

For Bi-Fold doors, the rough opening width is 1 1/4″ larger than the total nominal width of the doors. If using a pair of 2’0″ bi-fold doors, each door is 1’0″ nominal width. Since Bi-fold doors are net sized to fit he frame, the unit will fit a 2’0″ net inside width frame.

For a Bi-Fold door, the rough opening height is 1″ over nominal height or 13/16″ over net height. Since Timely standard frames are actually 3/16″ longer than the nominal height (Timely 7’0″ frames are actually 7’0 3/16″ long).

For a pair of Bi-Pass doors, the rough opening width is 1 1/4″ larger than the total nominal width of the doors minus 1″ for door overlap plus the width of any astragal mounted between the doors. If using a pair of 2’0″ doors, the frame will be fabricated 3’11” inside width to accommodate door overlap.

To install a Timely door frame, sidelight frame or borrowed light frame inside an existing opening instead of installing the frame over the outside of the wall surface, a prefinished steel sub frame is recommended. A sub frame provides a solid substrate to anchor the frame, requires no special fasteners and matches the color of the finished frame. When anchoring the frame to any wall type other than steel or wood studs, this method of application is much easier to install. In addition, the frame can maintain a fire rating provided the wall construction is fire rated and the other opening components are fire rated. The sub frame is anchored to the existing structure and the finished frame is installed over the flange of the sub frame similar to a sill channel or ceiling channel installation. Opening dimensions and corresponding frame dimensions are:

To install a Timely door frame, sidelight frame or borrowed light frame inside an existing opening instead of installing the frame over the outside of the wall surface, a wood sub frame is recommended. A sub frame provides a solid substrate to anchor the frame, and requires no special fasteners for the frame. The wood sub frame must be adequately anchored to the existing opening material using lag bolts. If the existing material is masonry, lead shields are used with lag bolts. This application leaves a visible line around the opening exposing the sub frame material so it is recommended that the sub frame material be treated and caulked, especially for exterior applications. Be aware that the opening can only be fire rated if the wood sub frame has fire rated drywall on both sides to separate the door frame from the sub frame. Opening dimensions and corresponding frame dimensions are:

Some projects require the entry door frame or closet door frame to be installed between two parallel walls. When this situation occurs, there are two factors to be considered. The first issue is having enough space to install the desired door width. This is important if the opening must comply with ADA requirements for adequate path of travel width. The finished wall to wall dimension must be at least 4″ larger than the nominal door width if using TA-8, TA-23, TA-28 or TA-28M casing. If using TA-30 or TA-35 casing width is 4 1/2″ wider. The second issue is adequate blocking for the framing material at the door location. The wall must have solid blocking to attach the stub wall prior to installing the frame. Whether using wood studs or steel studs, proper fasteners must be used to achieve adequate support for the door frame.
