Notched Track Application

Notched track for blocking & backing

Notched Track is generally used for joist blocking or horizontal backing in walls to allow support for cabinets, appliances etc.

Notched Track is also specified in many hospital jobs to add support to the mechanical equipment that is mounted on walls.

Used in framing applications:

  • Floor joist blocking
  • Horizontal wall backing
  • Support for cabinets

Load Tables

INSTALLATION CONDITION 33MILS (20GA) TRACK 43MILS (18GA) TRACK 54MILS (16GA) TRACK
Shear / 0" Offset 2255 2815 3005
Shear / 1" Offset 765 1345 1500
Shear / 3" Offset 260 310 600
Tension 585 825 975

Notes:

1. Listed load values are nominal test load values, appropriate safety factors/resistance factors should be applied by the designer for calculating loads for intended use.
2. Shear / Offset (moment-rotation) Load refers to load directed in the plane of the wall.
3. Tension Load refers to load directed perpendicular to wall surface.
4. Tabulated loads include the contribution of 5/8" gypsum board.
5. Test loads were applied to the gypsum board and backing system through a 1/2" thick, 2-3/4" diameter steel plate secured with (4) #12 hex head screws.
6. Loads were applied directly through the steel plate or to a steel rod that cantilevered from the plate.
7. Typical failure mode in backing testing was the gypsum board failure.
8. 24-in o.c. stud spacing test results were similar/identical to 16-in o.c. test results.
9. Listed capacities are based on 68mils (14ga) 50ksi studs.

Installation:

The Notched Track in anchored to the metal studs with (3) #8 wafer head/pan head screws.  One screw at the center and one screw at 1" from the top and bottom edges.
