Installation Site Specifications
Document Use
This guide supports the door's Opening Preparation and Installation Instructions by providing information for constructing the rough opening. It does not constitute actual wall fabrication, construction, or material recommendations. Andersen is not obligated to perform on-site inspections.
Code Compliance
Compliance with all applicable laws, ordinances, building codes, and safety requirements is the responsibility of the architect, building owner, installer, and/or contractor.
Product Protection
Store doors and accessories off the ground, fully supported, and under cover, protected from weather and construction activities. Protect uncartoned components and continue to protect the door from construction activities and floor traffic after installation.
Construction by Others
Andersen is not responsible for building construction conditions or performance beyond the door's perimeter. Attachment methods and fastener selection are the responsibility of the architect, building owner, installer, and/or contractor. For door replacement situations, Andersen is not responsible for inspecting the existing rough opening's structural integrity or header load-carrying capabilities.
Thank you for choosing Andersen.

Floor Requirements
- The floor must be structurally sound, flat, and level across the entire frame width and depth.
- It must have a load-carrying capacity of 100 pounds per lineal foot.
- Maximum deflection of 1/16" over the span of the opening after loading is permitted.
⚠️ WARNING: Verify there are no electrical, plumbing, or HVAC components in fastener locations. Failure to do so could result in injury or property damage.
Fastening
Head Jamb and Side Jamb(s)
- Use #10 countersunk flat head screws (not supplied) to attach to wood structural framing members with a 1-1/2" minimum fastener embedment.
- For structural steel studs, use #10 self-drilling countersunk flat head screws (not supplied) with 3 full threads of engagement.
- Jacking screws are located 1-1/2" from the exterior edge of the jambs.
Sill Fasteners
- For wood structural framing members, use 1/4"-20 x 4" hanger bolts (not supplied) with a 1-1/2" minimum fastener embedment.
- For masonry, use 1/4"-20 x 4" threaded rod (with nut and washers) with a 1-1/4" minimum fastener embedment. Masonry fasteners must be set back a minimum of 1-1/2" from the concrete slab's edge.
Sill Support
- The sill must be supported full depth. Refer to structural support options below if the existing slab/floor does not extend far enough.
- Sill support material is supplied by others.
Liftslide Door Flush Sill with Drainage Track Support Options
Diagrams illustrate various sill support methods:
- Full Slab/Floor (Typical): The floor slab extends fully under the sill.
- Aluminum Angle Support: An aluminum angle provides support when the floor slab is insufficient.
- Wood Support: Wood blocks are used to support the sill.
- Floating Slab: Accommodates an expansion joint, indicating the sill is not directly attached to a continuous slab.
- NO Support: Not recommended, where the sill lacks adequate support.
Liftslide Door Dimensions
Door dimensions refer to the outermost exterior of the frame components. Rough opening dimensions are provided in the supplied shop drawings.
Rough Opening Dimensions
These are recommended dimensions for proper installation and may need to be increased to accommodate building wraps, flashings, sill panning, brackets, and fasteners. The rough opening must provide structural framing members at all anchoring locations. The header must allow a maximum deflection of 1/8" over its span when fully loaded. Ensure the sides of the rough opening are square to the exterior wall due to large jamb depths.
- Liftslide Door Rough Opening: 1" wider and 2-13/16" higher (1/2" at the top and 2-5/16" at the dap-out) than door dimensions.
Header Height
Rough opening header height is measured from the bottom of the dap-out, which is 2-5/16" below the top of the finished floor. Adjust calculations if deviating from this dimension.
Liftslide Door with Third Party Automation (by Others)
Andersen can offer limited assistance with rough opening recommendations for doors intended for third-party automation systems.

Typical Drainage Manifold (recommended)
(Installation by others, e.g., plumbing professional)
Diagrams illustrate the drainage manifold system for flush sills with drainage tracks.
- NOTICE: A positive drainage slope must be maintained throughout the Drainage System. Failure to do so could result in property damage.
- NOTICE: DO NOT join more than two (2) drain tubes before connecting to the manifold. Doing so could result in property damage.
- NOTICE: Check Valve must have a maximum crack pressure of 0.5 lbs. Failure to do so could result in property damage.
The system includes drain tubes, connectors, a 1-1/4" Check Valve, and a clean-out. Piping should have a minimum 1-1/4" ID and be routed to the exterior or interior using a sump system.
IMPORTANT: 1-1/4" minimum ID (inside diameter) is needed for Certified Water Rating.
