Dual Interlocking Hinge Series

The DIH Series is designed for expansion joint openings with the ability to provide a smooth and virtually impact-free transition between opposing floor surfaces in addition to accommodating heavy rolling loads and multi-directional seismic movement. The dual interlocking center slide plates are hinged to allow the system to remain flush with finished floor surface. The interlocking slide plate assembly utilizes three rubber anti-vibration dampers to eliminate any metal-to-metal noise and to resist the infiltration of liquids. more

Larry Michael Petree 2016 

LarryPetree.jpg For over 40 years Larry Petree has contributed to the construction community serving on various industry committees on fire barrier safety and standards for building codes.  He has served with MM Systems as an engineer and heading our research and development group.  His patented designs and contribution to product design and engineered solutions have helped countless thousands to have safer functioning buildings throughout the world.

Larry routinely fielded calls from architects and design professionals who needed assistance selecting appropriate expansion joint covers or fire barrier for use in their new designs or designing a transition from one system to another.  Larry’s last act of service to MM was assisting an architect on November 24th.  Larry fell ill and never recovered from the complications.  On February 3rd,  he went home to his eternal reward.   Larry will be missed by the MM Family.  His contribution to buildings around the world will be felt for years to come.
