This PVC, white cover is used on an Untailed Terminal Box (UTTB). The UTTB is mounted outdoors on poles. It is used as a joint enclosure for aerial telephone cable distribution. A chain is provided to secure the cover to the pole when it is removed from the UTTB. It allows access for fault finding and/or line testing. The cover is made of PVC with a UV inhibitor, to ensure a long service life outdoors. The box provides a secure, weatherproof housing, for the jointed aerial, telephone cables.
