Continuous Hinge for Lead Lined Door

Roton 780-224LL Lead-Lined Continuous Concealed Leaf Hinge

The Roton 780-224LL is a heavy-duty, lead-lined continuous geared hinge designed specifically for 1-3/4 inch lead-lined doors used in medical, diagnostic, and radiation-shielded environments. This hinge is commonly specified for X-ray rooms, imaging suites, and other shielded openings where door hardware must maintain radiation integrity while supporting increased door weight.

The concealed leaf, mortised design provides a clean, flush appearance while evenly distributing door weight across the full height of the door and frame. This reduces stress on the door assembly, minimizes sagging, and extends service life compared to traditional butt hinges.

The 780-224LL includes a double row of fasteners, allowing secure attachment through lead-lined door edges without compromising shielding performance. Its continuous geared construction delivers smooth, controlled operation even on heavy shielded doors.
