Why does a standard toilet partition door have gaps?
Providing enough space so that the toilet partition door can swing freely creates gaps between the door and the pilasters on either side of the door. The standard gap width in a well-constructed, pilaster-based toilet compartment is 3/16 inch, which is large enough to create a sightline into and out of the bathroom stall.
How do you eliminate the door gaps and improve privacy?
Plastic toilet partition (solid plastic or phenolic materials) projects that require a higher level of privacy and elimination of door gaps will require “no-peek’ doors (also known as shiplap doors), a solution that completely eliminates the door gaps. In order to achieve “no-peek” or no sightline toilet partitions, privacy rabbeting is the quick and easy solution.
What is privacy rabbeting?
Rabbeting is a CNC machinery production process whereby a slot is cut parallel to, and along the edge of, a plastic toilet partition door and pilaster. Rabbeted edges on the strike side of each door mate with a coinciding rabbeted edge on each pilaster provides for ultimate privacy on the latch side of the toilet partition door. This sandwich technique (as seen in the below illustration) results in a complete overlapping door and pilaster, completely eliminating any sightlines and ability to peek into bathroom stalls.
For metal toilet partitions, utilize privacy strips to achieve the no-sightline privacy toilet partition system.
