Abstract

A duct for distributing one or more telecommunication lines comprises an elongated body having a length and a conduit portion with a lengthwise bore formed therein. The conduit portion contains one or more telecommunication lines. The duct also includes a flange extending lengthwise adjacent the main body to mount the duct to a mounting surface, such as a wall. The duct also includes an adhesive layer disposed on a surface of the flange, the adhesive layer comprising a removable adhesive to permit removal of the duct from the mounting surface after mounting.

First claim

What is claimed is:

1. A duct for distributing one or more communication lines, comprising:
an elongated body formed from an extruded polymeric material having a length and a conduit portion with a lengthwise bore formed therein, the conduit portion disposed on a first surface of a flange structure extending lengthwise adjacent the elongated body to mount the duct to a mounting surface, the conduit portion being pre-populated with one or more communication lines;
an adhesive layer disposed on a second surface of the flange, the second surface being opposite the first surface, the adhesive layer comprising a removable adhesive to permit removal of the duct from the mounting surface after mounting.

2. The duct of claim 1 , wherein the adhesive layer comprises a stretch release adhesive.

3. The duct of claim 2 , wherein the stretch release adhesive comprises one of an acrylic-based adhesive, a rubber-based adhesive, and a silicone-based adhesive.

4. The duct of claim 2 , wherein the stretch release adhesive comprises a highly extensible backing.

5. The duct of claim 1 , wherein the elongated body has a form factor (length versus width) of at least 25 to 1.

6. The duct of claim 1 , wherein the duct includes at least one additional conduit, wherein the first conduit is configured to contain at least a first optical fiber communication line and the additional conduit is configured to contain at least a second optical fiber communication line.

7. The duct of claim 1 , wherein the one or more communication lines includes an electrical wire.

8. The duct of claim 1 , wherein the one or more communication lines comprises a high speed Ethernet communication line.

9. A removably mountable article, comprising:
an article being pre-populated with one or more communication lines having an elongated body formed from an extruded polymeric material having a conduit portion with a lengthwise bore formed therein having a form factor (length versus width) of at least 25 to 1 and a bottom surface along a length of the elongated body; and
an adhesive layer disposed on the bottom surface of the article, the adhesive layer comprising a removable adhesive to permit removal of the article from a mounting surface after mounting.

10. The removably mountable article of claim 9 , wherein the elongated body is formed from a flexible material.

11. The removably mountable article of claim 9 , wherein the elongated body is formed from a material that is at least substantially rigid.

12. The removably mountable article of claim 9 , wherein the elongated body has a form factor (length versus width) of at least 50 to 1.

13. The removably mountable article of claim 9 , wherein the adhesive layer comprises a stretch release adhesive.

14. The removably mountable article of claim 13 , wherein the stretch release adhesive comprises one of an acrylic-based adhesive, a rubber-based adhesive, and a silicone-based adhesive.

15. The removably mountable article of claim 13 , wherein the stretch release adhesive comprises a highly extensible backing.
