- works great as an outdoor PVC cable junction box (I buried the cable/fiber deep to avoid service disruption) - I have it Part chosen in the box store instead of the standard PVC electric because it has a lower profile (3" instead of 4+) and is slightly more attractive. The plastic screws work fine. - tight or they'll break) This isn't rocket science - it is is plastic - be careful - if this box is exposed to direct sunlight it is recommended to paint it for extra protection. Use a plastic primer for the first coat)
