Maximum Load Weights for Various Types of Piano Hinges

Piano hinges are also known as continuous hinges. They are one of the most common types of hinges found in various types of installation projects. Below are maximum load weights recommended for the different types of piano hinges.

Load Strength

Piano hinges are very common and the load strength of the piano hinge is determined by a couple different things. They are first determined by the number of knuckles in the hinge and second, it is determined by the number of fasteners. The load is actually spread right across the length of the hing. A few examples are to follow.

• Standard 24" Length Hinge:This hinge will give you about 60 pounds of maximum weight. So, the spread of weight on this hinge is 2.5 pounds per 1 inch of the hinge.

• Plastic Piano Hinge: A 2 inch plastic piano hinge can typically handle up to 100 pounds of load per linear inch of the hinge. The plastic piano hinge is an economical alternative to a piano hinge constructed of steel or other metal material.

• Plated Finished: Some smaller hinges that are anywhere from 1 inch to 1.5 inches in width are great for lighter load projects. These types of piano hinges usually only have 5 knuckles. They offer great load bearing from one end to the other and are good for light weight applications such as for kitchen cabinets and pantries.
