Key Advantages

-Stainless Steel Material
Made from stainless steel, offering resistance to ordinary moisture-related corrosion compared with unprotected carbon steel. It is suitable for door hardware applications where routine cleaning and maintenance are carried out.

-5" x 3" Size
Features a 5-inch by 3-inch nominal hinge size, providing a clear dimension reference for door installation or replacement. Users can compare the size with the existing hinge and door frame before selecting the correct fitting.

-3.0mm Hinge Thickness
The specified 3.0mm thickness provides a defined hinge-leaf thickness for installation planning. It helps installers check compatibility with the existing hinge recess, door leaf and frame without assuming an unspecified load capacity.

-Supports Door Opening and Closing
The hinge connects the door leaf to the frame and allows the door to swing through its intended movement. Correct positioning and installation help the door operate smoothly during regular opening and closing.

-Practical for Installation and Replacement
Suitable for new door installations and replacing existing hinges when the dimensions, hinge pattern, mounting holes and door requirements match. This makes it useful for routine carpentry, renovation and door maintenance work.
