Deep leg tracks are typically 50mm deep, and extra deep sizes are 70mm deep. Standard leg dimensions are usually 25mm or 32mm, with the deeper tracks allowing for deflection head details.
Here's a breakdown:
- Standard Leg Tracks: Generally 25mm or 32mm in height (the width that typically attaches to a structure).
- Deep Leg Tracks: 50mm in depth.
- Extra Deep Leg Tracks: 70mm in depth.
The increased depth of deep and extra deep tracks accommodates deflection head details. This allows for movement and expansion in building structures, preventing damage to the wall system. The "leg" of the track refers to the vertical portion that's attached. Therefore, a "deep leg" refers to the extended depth of that leg.
