COE Stainless Steel Perforated Impression Tray, #S20, Lower, Large, 264201, 1/Pkg

COE Regular Perforated Metal Impression Trays are stainless steel, full-arch lower trays that are rigid yet bendable for an individual fit. The perforated design and welded rimlock borders allow impression material to lock in and pressure to build up, and tray adhesive is recommended to prevent separation during removal. The #S20 is a large lower tray (reference 264201), supplied individually; note that larger tray numbers indicate smaller trays.
