Upgrade your interior doors with OMANSKO 18-pack black door hinges

This set delivers 18 matte black hinges designed for interior doors with square corners. Each hinge measures 3.5 x 3.5 inches and uses a sturdy square 6-hole pattern, making it a practical choice for refreshing multiple doors at once. A common setup is three hinges per door to help balance weight, improve alignment, and extend door life without complicating installation.

Installation tips and care

• Before you start, measure door thickness and mark hinge locations. Pre-drill pilot holes to help screws bite cleanly.
• Align leaves evenly, then fasten with the included screws. Avoid over-tightening to prevent binding.
• Keep hinges dry and lightly lubricate moving parts periodically for smooth operation.
