Deep Leg Deflection Track System

Traditional, single-track deflection assembly for interior partitions & curtain-wall framing

This traditional assembly accommodates the deflection of the building structure at the head of wall.

Found in:

Interior Framing > Head-of-Wall Deflection Systems

Exterior Framing > Head-of-Wall Deflection Systems

Description

The single long leg track assembly requires 1-1/2" cold-rolled channel and 1-1/2" x 1-1/2" 16-gauge EasyClip™ Clip Angles (U-Series™) (or other bridging method) installed continuously throughout the uppermost punch-outs to align the studs vertically within the plane of the wall. Deflection track details must be designed for the specific conditions of a building to accommodate the required deflection and end reactions of the studs. Deflection tracks cannot be used in axial load-bearing stud conditions or above continuous window spandrels.

Nonproprietary system.
Traditional framing components.
Requires bridging at top of wall.
