After you've worked to design a naturalistic reptile habitat, finish the look by creating a coordinated route to hide power cords and air tubes. A generous 2 1/8" in diameter, the Cord Access Port can be fastened to any screen material or acrylic sheet 3/32" (2.36 mm) or less in thickness. To install simply cut a hole, snap the two components of the port together and add a plug that keeps reptiles and feeder insects from exiting the terrarium.
