Claims
- 1. A hanger for connecting a duct to a support; the hanger comprising:
a main shaft having first and second opposed ends; a hook connected to the main shaft adjacent the first end of the shaft; the hook adapted to engage the duct; and a loop connected to the main shaft adjacent the second end of the shaft; the loop adapted to receive a connector; the connector being adapted to engage the support.
- 2. The hanger of claim 1, wherein the main shaft is substantially rectangular in cross-section.
- 3. The hanger of claim 1, wherein the loop includes a rolled portion and a tongue portion; the rolled portion defining an opening adapted to receive the connector.
- 4. The hanger of claim 3, wherein the tongue portion has an end; the end adapted to align with the support to properly position the hanger with respect to the support.
- 5. The hanger of claim 3, wherein the main shaft has a front surface and a rear surface; the hook opening in a direction outward from the front surface of the shaft; the front surface of the shaft adapted to face the duct.
- 6. The hanger of claim 5, wherein the loop has a rear surface that is coplanar with the rear surface of the main shaft such that no portion of the loop projects out from the rear surface of the shaft whereby two duct hangers may be disposed back-to-back with their rear surfaces contacting each other along the length of the main shaft.
- 7. The hanger of claim 1, wherein the hook projects substantially perpendicular from the main shaft.
- 8. The hanger of claim 7, wherein the hook defines an opening adapted to receive a connector.
- 9. The hanger of claim 1, wherein the shaft defines an opening intermediate the hook and the loop; the opening adapted to receive a connector.
- 10. The hanger of claim 1, wherein the hook is adapted to pierce the duct.
- 11. The hanger of claim 10, wherein the hook includes a first portion and a second portion; the first portion extending substantially perpendicular from the main shaft; the second portion projecting at an angle from the first portion; the second portion being pointed.
- 12. The hanger of claim 10, wherein the hook includes a first portion and a second portion; the first portion being U-shaped; the second portion being substantially parallel with the main shaft.
- 13. The hanger of claim 1, wherein the hook includes a first portion and a second portion; the first portion being U-shaped; the second portion being substantially parallel with the main shaft.
- 14. A hanger for connecting a duct to a support; the hanger comprising:
a main shaft having first and second opposed ends; the main shaft having a front surface and a rear surface; a hook connected to the main shaft adjacent the first end of the shaft; the hook being substantially perpendicular to the main shaft; a loop connected to the main shaft adjacent the second end of the shaft; the loop having a rear surface; and the rear surface of the loop being substantially coplanar with the rear surface of the main shaft.
- 15. The hanger of claim 14, wherein the loop includes a rolled portion and a tongue portion; the rolled portion defining an opening adapted to receive a connector; the tongue portion having an end; the end adapted to align with the support to properly position the hanger with respect to the support.
- 16. The hanger of claim 15, wherein the hook defines an opening and wherein the main shaft defines an opening; the openings adapted to receive connectors.
- 17. A hanger for connecting a duct to a support; the hanger comprising:
a main shaft having first and second opposed ends; the main shaft having a front surface and a rear surface; a hook connected to the main shaft adjacent the first end of the shaft; the hook being pointed and adapted to pierce the duct; a loop connected to the main shaft adjacent the second end of the shaft; the loop having a rear surface; and the rear surface of the loop being substantially coplanar with the rear surface of the main shaft.
- 18. The hanger of claim 17, wherein the loop includes a rolled portion and a tongue portion; the rolled portion defining an opening adapted to receive a connector; the tongue portion having an end; the end adapted to align with the support to properly position the hanger with respect to the support.
- 19. The hanger of claim 16, wherein the hook defines an opening and wherein the main shaft defines an opening; the openings adapted to receive connectors.
