Yet another alternative to the classic Megill gauge pins. I make these by hand from flexible polyurethane rubber in my own molds. Just cut a slot in your tympan, slide the foot through, and fasten with your choice of tape, double-sided tape, or even a glue stick. There’s no foam to tear or built-in adhesive to deteriorate.
I developed these because I couldn’t avoid the Pauli Exclusion Principle — that two identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously. At least I think that’s what I did, remembering how I had crushed a numbering machine in a 10x15 Chandler & Price many years ago. However, they are still thicker than the 152SB plates from Boxcar, so you do need to place them outside the base in the furniture or open areas of the chase.
Although they are very flexible, they’re not really compressible in the way plastic foam is. However, I did test one out of curiosity. I squeezed it in a vice down to about half its thickness and it bounced back to its original size. I wouldn’t make a habit of that, though.
No adhesive to wear out; use them until you lose them
Fasten to tympan with masking tape, double-sided tape or glue stick
Your sheet can’t slip between the gauge and tympan
Upper flap is angled for easy insertion of sheet; it bends downward under any pressure
Easily cut down to smaller size with scissors or knife if needed
The price is for a package of 4 — three for a standard set up, plus one for a spare or to cut down to a smaller size with scissors or knife.

Note to buyers outside the USA:
I ship free to eBay's international shipping service in Kentucky. After leaving there, they will be subject to an additional international shipping charge. And in most cases the destination country will add an import (customs) charge. These vary from country to country, and sometimes they will be almost as much as the item itself. I apologize in advance for this, but it is entirely beyond my control.
