Markar HS303 Hinge

This half-surface pin and barrel continuous hinge can be used to repair and replace existing hinges on both fire-labeled and non-labeled openings.

The hinge fits into the gap left after standard butt hinges are removed. It can assist in reversing the handing of a door, or to reverse the swing of a door hung in an evenly-rabbeted frame.
