Shop Pilaster Styles ›Installation & Finish
Dry-fit the pediment, crosshead and pilasters before fastening. Follow the product drawings and Spectis installation instructions, including the specified adhesive on all bedding and butt joints. Secure each component as directed, finish joints and fastener holes, and paint after installation. These components are decorative trim, not structural supports.
How to Install Pediments and Pilasters ›Shipping
The long side is over 48 inches, so it ships LTL freight, the same as a long header.
A verified commercial address accessible to a 52-foot trailer. A house with a business in it does not qualify.
If the carrier calls the address a residence, a $275 fee is added, and you get a confirmation letter so you can correct the address or pay the extra freight.
Typically ships within 2–3 weeks from the order date. Allow additional time for freight transit.
