Hettich's Optimat hinges are an excellent choice for face frame cabinetry with numerous overlay options available. Robust construction, reliable operation, and economical pricing all characterize this series. Six-way adjustment helps ensure that doors fit perfectly. Even after years of use, the doors can still be easily adjusted. The Optimat 3E series is a one-piece assembly, which means no mounting plate is necessary. It has a 108° opening angle and a wraparound hinge-to-frame mount. This particular hinge is designed for 1-1/4" overlay with press-in hinge-to-door attachment, utilizing pre-attached 8mm dowels.
