The MB Erector Connector reduces installation time in precast flange-to-flange connections by eliminating welding slugs and reducing field welds. Embedded in the flange, the internal weld plate is extracted only as far as needed to make the connection. It eliminates the tension loads caused by expansion and contraction between precast elements, while resisting horizontal and vertical shear. Meadow Burke. 877-518-7665. www.meadowburke.com.
Duro-Nox is a chemically reactive, water-based sealer that penetrates the pores of concrete surfaces. It produces calcium silicate gels, which harden, densify, and seal the concrete to resist abrasion, impact damage, and stains. The product is 100% inorganic, non-toxic, and contains no VOCs, making it a good choice for use on green projects. Nox-Crete Products Group. 800-669-2738. www.nox-crete.com.
