This small spring loaded hinge is made of two parts; a spring loaded pin housing and a plastic bushing (pin receiver)
Both hinge parts install by drilling a hole and press fitting them in place
The spring loaded pin housing measures 1-3/8" long by 1/4" diameter. The pin diameter is 5/32" and projects 1/4"
The plastic bushing is 7/16" in outside diameter
Maximum door opening is approximately 140 degrees
This hinge will work on door thicknesses ranging from 1/2" to 13/16"
This hinge is made of plastic with a steel pin and spring.
PLEASE NOTE: This hinge is not a "self-closing" hinge. The spring is in the pin receiver and is meant only to keep the pin in place after installation.
