Bulkhead Feedthroughs - 2 pairs

A feedthrough button allows a smooth protective path to be formed through a wall or other barrier having a hole.  The path may be used to safely pass wires, tubing, probes, etc. through the hole, or simply to allow air exchange.  With a feedthrough button you can make a ratty, unkempt looking orifice appear cleaner and more professional.  Two male and two female parts are included, which allow you to create two different feedthrough pairings.  The parts are connected using a central rod that is easily cut with a small pair of snips or wire cutters.

The male and female pairings screw together through a hole in the target material.  The feedthroughs go both ways - they can be screwed together from the front or the back.  In one direction the male and female pieces screw together tightly to create a stronger rip resistant hole in thin materials like thick paper, plastic, fabric, or rubber/latex sheeting.  In the other direction they can provide a feedthrough through slightly thicker materials such as corrugated cardboard or leather.  How you screw these parts together is only limited by your imagination and dependent on your personal needs and preferences.  If you know why you need this you probably already know how to use it properly!
