The primary benefits are superior longevity and flexibility. The soft lead adapts to building movement, protects the underlying sealant from UV and moisture damage, resists corrosion, and prevents joint checking. This results in a more durable, weather-resistant seal than exposed sealant.

They are ideal for protecting joints in stone and masonry construction. Common applications include parapet copings, cornices, belt courses, window and door lintels, and entrance steps, especially in historic preservation and restoration projects where long-term durability is critical.

'Type A' is a flat cap configuration used for joints between masonry units on the same plane, such as across the top of a coping. 'Type B' is a 90-degree cove cap designed for right-angle joints, like where a horizontal stone sill meets a vertical brick wall.

All our joint caps are supplied in standard 6-foot lengths, which can be easily cut and fitted on-site to meet project requirements. We typically ship materials within 48 hours of receiving an order, ensuring your project stays on schedule.
