• The 25" by 54" model requires a rough opening of 25" by 54"  

• The 3'0 by 6'0 Hallway model requires a rough opening of 36" by 72" framed opening.

• The 4'0 by 4'0 model requires a rough opening of 48" by 48" framed opening.

•  The 4'0 by 6'0 Garage model requires a rough opening of 48" by 72" framed opening.

It is very important to make sure that the opening is square.

It is necessary the attic or storage area be framed for the appropriate load.

The builder, Architect, or Engineer should decide and have installed the correct sizing of beams and joists for each individual application.

The Attic Lift
requires certain specific framing requirements for installation.  They are as follows:

• The rough opening should be bordered by a minimum of 3" of framing thickness.  This can be a double 2x beam,  a laminated beam, or some other material specified by your builder.  This thickness is necessary to give a platform area for the upright posts to be fastened.

• At each corner of the rough opening, fasten a common 4 by 4 fastening plate using screws.

• In the plate, stand and level common 4 by 4 posts and fasten into the roof framing.

• It will be very rare for the posts to line up alongside a roof joist and be level, so use the appropriate blocking material during this installation.

• It is the homeowner/builders responsibility to make sure there are no obstructions around or above the hole, especially by plumbers, heating and air conditioning or electrician companies.

The Attic Lift
can also be installed in many other building materials such as steel framing as long as the rough opening framing and the upright wood post are the same.

• How is the unit installed in an existing attic?  The installation in an existing attic will vary.  It would be best for the consumer to contact a builder or architect for advice on framing. 

• What does the builder or customer need to do in order to be ready for a lift installation?  They need to have the finished opening framed in, four posts installed in the proper places, and two pieces of 2 by 6 lumber need to be available to the installer about 5 feet long.

• Why does the unit need posts?  The unit needs posts because they are an integral part of the design and are the easiest most readily available structural uprights for this type of lift.
