Inpro Expansion Joint 210: Durable Solutions for Building Movement

They are ideal for protecting joints in stone and masonry, especially in historic preservation. Common uses include copings, parapets, cornices, balustrades, window and door lintels, and entrance steps. Both flat (Type A) and right-angle (Type B) joints can be protected.

The soft lead has a low elastic modulus, allowing it to remain flexible and 'creep' into new configurations as the building moves or settles. This prevents the sealant from tearing or losing adhesion, which is a common point of failure in rigid masonry joints.

Yes, while widely used in historic restoration, it is also highly effective for new construction. Specifying WEATHERCAP® from the start ensures long-term joint durability, reduces future maintenance costs, and protects against moisture penetration from day one.

Yes, the lead cap can be painted to match the surrounding masonry. If left unpainted, its surface rapidly oxidizes to a neutral grey color that naturally blends with most stone and masonry, making it visually unobtrusive.

We offer stock sizes for Type A (flat) and Type B (90° cove) caps for joint widths from under 3/8" to 1 1/2". All products are supplied in 6-foot lengths. Custom sizes can be manufactured upon request for special projects.
