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:
