California listing 8140-2134:0105 covers the specified Boral TruExterior profiles and sizes, including separately dimensioned Bevel siding.

The September 2025 OSFM handbook lists Channel Bevel, V-Rustic, Cove/Dutch, Shiplap, and Channel Shiplap at 5.5–11.5 inches wide and an actual thickness of 11/16 inch. Bevel has its own dimensions: widths of 5.5–9.25 inches and thicknesses of 3/4 and 1/2 inch tapering to 7/16 and 3/16 inch. Keep those two sets of dimensions separate when choosing a profile.

Listing 8140-2134:0105 identifies the siding under category 8140 and names SFM 12-7A-1 as the test protocol. The listing is useful at the profile-selection stage because a shared TruExterior name alone does not identify which dimensions apply. Check the selected profile against the live record, and use the manufacturer's installation instructions and product data sheet to complete the specification.
