Exterior raceway system for cables

1. An exterior raceway system for attachment to an exterior wall structure of a building for concealing and protecting one or more cables against the weather, the system comprising at least one elongated base member having a back wall that is attachable to an exterior wall structure of a building, outturned flanges along opposite side edges of the back wall, and an elongated cover member that is selectively attachable to the base member, wherein the cover member is generally U-shaped and has inturned flanges along opposite side edges of the cover member sized for placement over and completely around the outturned flanges of the base member, and wherein the inturned flanges of the cover member are flexible to provide a snap fit over and completely around the outturned flanges of the base member.

2. The system of claim 1 wherein one of the inturned flanges of the cover member is hingedly connectable to one of the outturned flanges of the base member.

3. The system of claim 1 wherein outwardly protruding bridge lances are provided at spaced intervals along the length of the back wall of the base member for insertion of ties through the bridge lances for tying one or more cables to the back wall.

4. The system of claim 1 which includes a plurality of elongated base members that are attachable to the exterior wall structure in end to end relation to one another, and a plurality of elongated cover members that are selectively attachable to respective base members.

5. The system of claim 4 further comprising seam covers for covering gaps or seams between adjacent cover members, the seam covers having substantially the same cross-sectional shape as the cover members but are sized to closely fit over end portions of adjacent cover members.

6. The system of claim 4 further comprising wall straps for further securing the cover members and associated base members to the exterior wall structure.

7. The system of claim 4 further comprising an angled fitting for receipt of spaced apart ends of two of the base members and associated cover members for routing cable in different directions.

8. The system of claim 7 wherein the angled fitting is comprised of two halves connectable together around the spaced apart ends of two of the base members and associated cover members.

9. The system of claim 4 further comprising a tee fitting for receipt of spaced apart ends of three of the base members and associated cover members for routing cable in different directions.

10. The system of claim 9 wherein the tee fitting is comprised of two halves that are connectable together around the spaced apart ends of three of the base members and associated cover members.

11. The system of claim 4 further comprising an end cap fitting for closing off an end of one of the base members and associated cover members.

12. The system of claim 4 further comprising a stepped adaptor for receipt of an end of one of the base members and associated cover member for connecting the raceway system to different sized square tubing.

13. The system of claim 4 further comprising a stepped adaptor for receipt of an end of one of the base members and associated cover member for connecting the raceway system to different sized round tubing.

14. The system of claim 4 further comprising an end mounting adaptor for receipt of an end of one of the base members and associated cover member.

15. The system of claim 4 further comprising a right angle corner fitting for receipt of spaced apart ends of two of the base members and associated cover members for maintaining a minimum bend radius in cable around a right angle outside corner of an exterior wall structure.

16. The system of claim 1 wherein the outturned flanges of the base member are stepped outwardly from opposite sides of the back wall of the base member a sufficient distance to accommodate the inturned flanges of the cover member beneath the outturned flanges when the base member is attached to an exterior wall structure.
