Exterior Framing Components

Exterior Structural Stud

C-Studs are lightweight, cold-formed galvanized steel members used in axial load bearing walls, curtain‑walls, floor joists and roof truss framing. C-Studs are available in a wide array of sizes, flanges, gauges and yield strengths to obtain optimal performance at minimal costs.


Gauges: 20, 18, 16, 14, 12

Flange: 1-3/8”, 1-5/8”, 2”, 2-1/2”, 3”, 3-1/2”

Return: 3/8”, 1/2”, 5/8”, 5/8”, 1”, 1”

Exterior Structural Track

Structural track is a U-shaped framing component used as top and bottom runners to secure wall studs. Structural track is also used as end support closures for joists at exterior or foundation walls, head and sill plates of wall openings and solid blocking.

Gauges: 20, 18, 16, 14, 12

Web: 2-1/2”, 3-1/2”, 3-5/8”,4,5-1/2”, 6”, 8”, 10”, 12”, 14”

Leg: 1”, 1-1/4”, 1-1/2”, 2”, 3”

SLP-TRK Slotted Track System (BDTK)

The SLP-TRK® Slotted Track is one of the most cost-effective, positively attached fire-rated deflection systems.

Spazzer® 5400 Spacer Bar Spazzer® Bar Guard™

The Spazzer® 5400 Spacing Bar is a prenotched bridging and spacing bar engineered to facilitate the rapid erection of exterior curtain wall framing, load-bearing walls and high interior partitions constructed with structural studs.


  • Reduces labor up to 40%
  • Eliminates clip angles, bridging clips and welding
  • Pre-notched at 12", 16" and 24" intervals, so no layout is needed

Double Track Systems

Traditional, Double Track or track-over-track curtain-wall deflection system.


  • Eliminates bridging
  • Requires custom top track/longer lead times

U-Channel and EasyClip Clip Angles

Traditional cold-rolled bridging with clip angle and screw attachment.

  • Traditional bracing to prevent stud rotation
  • EasyClip™ U-Series™ clips are punched for easy attachment
  • Labor-intensive assembly
