Hager 1150

Full Mortise Hinges have one leaf mortised in the door edge and the other leaf mortised in the jamb. This is the most common hinge application.
Spring hinges are for automatic closing of doors. Full spring tension may not be required on all hinges. Easily adjustable.
Number of hinges used determines maximum door weight and width. Strong wind conditions, drafts, carpeting drag, twisted/misaligned frames, or weatherstripping on doors may require additional spring hinges.
