Nomenclature
StiffClip RT650 is 6½” long, and may be used when wall studs do not align with roof framing member. The RT1300 is 13″ long, and is used when wall studs align with roof framing member. Clips are designated by length, followed by thickness and number of screws used in each leg (determined by load requirements – refer to load tables).
Example: Stud aligns with roof framing member (see application image)
Designate: StiffClip® 1300
* StiffClip RT650 are packaged in pairs. (shown right)

StiffClip® RT Applications
The unique design of MasterClip allows it to be installed either as a vertical deflection connection or a rigid connection. Attachment to the primary structure may be made with a PAF, screw/bolt anchors, or weld and is dependent upon the base material (steel or concrete) and the design configuration.

StiffClip RT1300 - Roof Tie Application
Installation Instructions
- To install the StiffClip RT, place one end flush against the roof framing member with the other end abutting the wall framing member.
- Attachment includes 2 or 4 screws in the upper and lower parts of each StiffClip RT.

Load Directions:
F1 = Lateral F2 = Horizontal F3 = Uplift
- StiffClip RT resists horizontal, lateral, and uplift loads.
- Allowable loads have not been increased for wind, seismic, or other factors.
- Number of screws designated represents the amount required in each leg of the clip.
- Loads listed reflect force in a single direction. When multiple loads act on the connection, it is the responsibility of the designer to check the interaction of forces.
- Torsional effects are considered on screw groups for F1, F2 & F3 allowable loads. It is assumed that half of the torsional moment is taken by the connection to the structure and half is taken by the connection to the stud.
