This is an adapter I designed for the Kramer TBUS-203xl. I picked up this on eBay for a good price but the inserts cost upwards of $60 per insert. These inserts also only contain 1 port. So I modeled my own that accepts keystone jacks. This means you can put whatever inserts you would like into this pop up for very cheap.

Printing on a textured bed produces a similar finish to the product and the included blank plates.
