Purchase this hush gasket for your knock box set up and your customers and employees will surely thank you. This heavy duty rubber gasket works best when placed between the knock box pan and black wooden surround to help dampen the bone jarring sound of the portafilter. This could possibly save your life one day.
Fits the Closed and Open bottom square knockboxes we make and Model 3 Knockboxes for the home (3003, 3003_BOO, KITD49, & KITD58) as well.
