For Precast Concrete and Cast-in-place Construction

The NMB Splice-Sleeve® System has been the original and most effective grouted sleeve coupler for full tension and compression precast, CIP, Tilt-up, and other connections for over 40 years. SA Class is equivalent to Type 2 coupler approved by ICC-ES in the United States. ICC-ES evaluated for Type 2 performance in high seismic areas. The NMB Splice-Sleeve System has been used at more than 21 million splices and has demonstrated that none have failed through the severest natural disasters such as Guam Earthquake in 1993, Kobe Earthquake in 1995, and Great East Japan Earthquake in 2011.
