Product Description:
Midwall™ is a tested alternative in partial wall assemblies, designed to support out-of-plane loading in cantilevered partial wall systems that are unsupported at the top track.
The out-of-plane loads are transferred to the floor system through a 1/2" thick plate nested in the flanges of the member with two 3/8" diameter fasteners (or {one} 1.2" diameter fastener for 250MW) used for the connection.
Midwall™ 24" is generally used in interior half walls of less than 48" in height. Attach Midwall to 54 mil stud with #12 screws through all pre-drilled guide holes. Other studs in wall are typical infill studs.
Midwall™ 48" is used in interior half walls equal to or more than 48" in height. Use one Midwall 48" as a substitute for a stud at the specified spacing, or attach to a 54 mil stud with #12 screws through all pre-drilled guide holes.
Simple Installation:
Options:
Available in two lengths, 24" and 48". Midwall™ may be used in place of standard framing members, or in conjunction with them to frame a wall:
- 2-1/2" wall width x 24" height Rated
- 2-1/2" wall width x 48" height Rated
- 3-5/8" wall width x 24" height Rated
- 3-5/8" wall width x 48" height Rated
- 6" wall width x 24" height Rated
- 6" wall width x 48" height Rated

Material Composition:
MidWall
MidWall Plate
The top track spanning between Midwall members acts as a load distribution member capable of distributing localized loads to multiple MidWall members. It is recommended to design track in these applications. Refer to the diagram above for an example of the distribution of the point load, P, to adjacent MidWall supports. At the end of the wall, Midwall is required at adjacent stud spacings. Designed spacing begins after two adjacent end supports.
