Trulite CT451 Part Correction in the 2022 r4 catalog
We made a mistake with this missing Sill component part in the framing system ID:4139, "B4 : CT451 Storefront (2 x 4-1/2) : 1 inch Glass : Thermal".
We added the CG451-4 Sill part instead of the correct CT451-4 part. You can make this correction yourself by editing this framing system, then clicking the Stock Length Material tab See the screenshot below for details.
The updated 2023 r1 has this correction.
