Engineered for Masonry: The Definitive Insert for Brick and Stone

The Gaines Keystone Series is designed to solve the two most common challenges in masonry installations: longevity and fit. Unlike standard steel inserts that corrode within years of being encased in mortar, our inserts are constructed from aerospace-grade, powder-coated aluminum. This ensures your column remains pristine, free from the rust stains that plague cheaper alternatives.

For New Construction & Masonry Projects: We provide precise rough-opening dimensions to ensure your mason can build efficiently without guesswork. The solid aluminum faceplate allows for a clean, flush finish against brick, stucco, or natural stone, acting as the architectural focal point of your entrance.

For Replacement & Retrofit: If you are replacing a rusted or damaged standard-sized insert, the Gaines Keystone is engineered to slide into most existing masonry cavities with minimal modification. Upgrade your curb appeal instantly without the expense of rebuilding the entire column.
