Notes/Conditions:
• Tensile loading is limited by plastic deformation
of the saddle clip
• X-GRRU resist shear by friction and is not
suitable for explicit shear load designs
Test data
Important note: Test data are for information only and can't be used for design. These data
are examples and not representing the whole range of applications and load cases. For more
