National Custom Hollow Metal is excited to announce a new partnership with Simonswerk North America! We have developed specially prepared hollow metal frames that are designed to accept the adjustable Simonswerk Variant VX hinge in primed galvaneal as well as 304 and 316 stainless steel for commercial doors. This new 3-way adjustable hinge and frame combination will allow for adjusting the door opening with precision and reduce precious time spent on installation.
