A removable drain trap assembly comprised of a clear plastic curved pipe member, a removable bottom closure member attached to the dip portion of the pipe member, and a gridlike member placed vertically within the dip portion of the bottom closure member. The gridlike member is placed along the vertical cross section of the assembly having maximum fluid flux to maximize object capture capacity. The gridlike member conforms to the cross sectional width of the dip portion and the bottom closure member to minimize fluid flow impedance. The bottom closure member is elongated and deepened to facilitate retention of smaller foreign objects which might pass through the gridlike member.
