Usage
Designed for installation at the bottom of doorways, the Colonial Plinth Block fits snugly where the door casing meets the baseboard, creating a clean, finished look. It is ideal for both new construction projects and renovation work where existing trim needs a cohesive finish. The block can be used in residential homes, apartments, and commercial spaces such as offices, hotels, and retail environments.
Because the block is unfinished, it can be painted to match any interior color palette or stained to complement hardwood flooring. Installers typically secure the block with finishing nails or adhesive, then fill any nail holes with wood filler for a flawless appearance. The block’s dimensions make it compatible with a wide range of door and window casings, providing flexibility for various architectural styles.

FAQ
Can I paint the plinth block before installation?
Yes, the block is unfinished and can be painted or stained either before or after installation. Pre‑painting allows for easier handling and a cleaner finish, while post‑installation painting ensures a seamless match with surrounding trim.
What type of nail or adhesive should I use?
Finishing nails (15‑18 gauge) work well for most applications. For a stronger bond, especially in high‑traffic commercial settings, a construction adhesive rated for wood trim is recommended.
Is this product compatible with non‑hardwood baseboards?
Absolutely. The block’s design focuses on the interface between the door casing and the baseboard, regardless of the baseboard material. It works equally well with MDF, PVC, or composite baseboards.
How do I ensure a tight fit during installation?
Measure the width of your door casing and the height of your baseboard before purchasing. The block is designed for casings up to 3‑1/4″ wide and baseboards up to 6″ high. Use a level and a small amount of adhesive to hold the block in place while nailing.
