This surface mount drip tray is constructed of 100% stainless steel. This drip tray comes with a detachable grill for easy cleaning. This drip tray comes with a threaded drain nipple that connects to a 1/2" drain line (drain line not included). This tray is ideal for applications where you can run a line from the drip tray to the nearest drain receptacle so you don't have to dump out the drip tray when it fills up.
