Best Column Caps for Effective Load Distribution (2023)

The soft lead cap covers the sealant, shielding it from UV radiation, weather, and physical damage. Its flexibility allows it to 'creep' and adapt as the building settles or moves, preventing the sealant from tearing or pulling away from the masonry (margin checking). This prolongs the sealant's life and maintains a weatherproof seal.

Type A is a flat cap designed for joints where masonry units are in the same plane, such as cross joints on copings, lintels, and cornices. Type B is a 90-degree cove cap used for right-angle joints, such as where a horizontal surface like a window sill or water table meets a vertical wall.

WEATHERCAP® is primarily used in historic masonry restoration and high-quality new construction. Common applications include protecting joints on parapets, copings, balustrades, cornices, belt courses, window and door lintels, sills, and entrance steps. It is ideal for preserving the integrity of landmark buildings and architect-specified projects.

Yes, absolutely. While renowned for historic preservation, WEATHERCAP® is also specified for new construction to ensure long-term durability of masonry joints. The A-2 Type A cap, for instance, is designated specifically for new construction installations. It provides a robust, lasting seal from the outset, reducing future maintenance needs.

As with any lead product, proper handling is required. The material is regulated under OSHA 29 CFR 1910.1025. Installers should always wear gloves and wash hands thoroughly after handling to minimize exposure. When installed, the lead is stable and poses no risk as it is embedded within the masonry joint.

All WEATHERCAP® products are supplied in standard 6-foot lengths, which can be easily cut to size on-site. We maintain a full manufacturing and supply chain, and materials for stock sizes are typically shipped within 48 hours of an order being placed. Custom sizes and configurations are also available upon request to suit unique project needs.
