Catchmaster 48R Glue Tray contains Hercules Putty to prevent the tray from being dragged around once a rat is glue to it.
Each pack contains two trays. The only difference between this one and the econo version is that this one has the Hercules Putty.
Each board measures 10.25" x 5.25". The glue tray is non-toxic and has a cherry scent.
