The Old Hardware Store has scores of small hinges. But many of them are slightly different from each other. Like this pair, they look like other pairs, but the measurement or hole pattern, or spine placement is a little different than other pairs. If you need more than one pair, you might search the catalog and find another pair that are very similar.
This neat brass duo measures one inch vertically and 7/8 inch across both wings. Each wing is 3/8 inch deep (or wide).
The pair has been lightly cleaned and ready to use. Brass screws will be included.
