Description
- Architectural hinges are thicker and of much higher quality than Residential Grade hinges (slightly more than 1/8″ material thickness).
- They are built to an industry-wide template. That means the screw hole pattern and hinge dimensions are the same in all 4″ x 4″ Architectural Grade Hinges. The same is true for all 4.5″ x 4.5″ Architectural Grade hinges. This allows you to replace Architectural Grade hinges without making changes to the mortise in your door and door jamb.
- All 4″ x 4″ and 4.5″ x 4.5″ Architectural Grade hinges use a screw hole pattern that looks like an arch. Residential Grade 4″ x 4″ hinges use a zig-zag pattern. This is one way to tell the difference between Architectural and Residential Grade hinges in the 4″ x 4″ size. Residential grade hinges are not made in the 4.5″ x 4.5″ size.
