1. Use these Roof Pitch to Hip/Valley Rafter Roof Pitch conversion tables only for hip/valley rafters that are skewed 45° right or left. All other skews will cause the slope to change from that listed.

Fastening Identification

Square Holes Purpose: To fasten a connector. Fill Requirements: Always fill, unless noted otherwise.

Diamond Holes Purpose: To temporarily fasten a connector to make installing it easier. Fill Requirements: None.

Triangular Holes Purpose: To increase a connector’s strength or to achieve max. strength. Fill Requirements: When the designer specifies max. nailing.

Obround Holes Purpose: To make fastening a connector in a tight location easier. Fill Requirements: Always fill, unless noted otherwise.

Round Holes Purpose:

Hexagonal Holes Purpose: To fasten a connector to concrete or masonry. Fill Requirements: Always fill when fastening a connector to concrete or masonry.

Pilot hole

To fasten a connector. Fill Requirements: Always fill, unless noted otherwise.

Speed Prongs Used to temporarily position and secure the connector for easier and faster installation.

Dome Nailing This feature guides the nail into the joist and header at a 45° angle.

Positive Angle Nailing (PAN) Provided when wood splitting may occur, and to speed installation.

Double-Shear Nailing The nail is installed into the joist and header, distributing the load through two points on each joist nail for greater strength. Double-shear nailing must be full-length catalog nail.

ITS/IUS Strong-Grip ™ The Strong-Grip ™ seat allows the I-joist to “snap” in securely without the need for joist nails.
