  • Expansion joint cap
    Patent number: 5888017
    Abstract: A resilient expansion joint insert member for insertion into the expansion joint between adjacent concrete floor slabs. As the concrete slabs move further apart due to settling or thermal contraction, insert member covers the widened gap.
