2. The housing of claim 1 , wherein the cam body engages the keeper to prevent the door from moving toward the second position when the cam is in the second orientation, wherein the first position of the door is generally perpendicular to the first panel, wherein the axis of rotation of the rotatable cylinder is perpendicular to the door, and wherein the second plane is parallel to the axis of rotation.
3. The housing of claim 2 , wherein the second end is spaced from the keeper when the cam body engages the keeper.
4. The housing of claim 1 , wherein the opening has a continuous periphery.
5. The housing of claim 4 , wherein the opening has a side wall, and wherein the cam body but not the cam second end contacts the opening side wall to maintain the door in the first position when the cylinder is in the second orientation and wherein the second end but not the cam body contacts an outer surface of the first panel when the cylinder is in the second orientation if the first panel is pulled away from the cylinder.
6. The housing of claim 1 including first and second brackets configured for supporting the housing in a rack.
7. The housing of claim 6 , wherein the housing comprises an optical fiber shelf.
8. The housing of claim 1 wherein the support member comprises a second panel parallel to the first panel.
9. The housing of claim 1 , wherein the cylinder is key actuated.
10. A housing comprising:
a first panel lying in a first plane and including a keeper;
a support member spaced from the first panel;
a door having a hinge edge hingedly connected to the support member and a free edge opposite the hinge edge, the door being shiftable between a first position with the free edge adjacent the first panel and keeper and a second position with the free edge spaced from the first panel and keeper; and
a lock mounted on the door, the lock comprising a rotatable cylinder having an axis of rotation and a cam connected to the cylinder for rotation with the cylinder, said cam having a first end and a second end spaced from the first end by a cam body, the second end extending at an angle to the cam body and lying in a second plane;
wherein, when the door is in the first position, the cam is shiftable from a first orientation with the cam second end spaced from the keeper to a second orientation with the cam second end overlying a side of the keeper opposite the cylinder to lock the door; and
wherein:
the keeper comprises an opening in the first panel;
the opening extends through the first panel and has a continuous periphery;
the first panel includes a first edge,
the opening includes a first portion having a first width in a direction perpendicular to the first edge and a second portion having a second width in the direction, the second width being greater than the first width,
the cam second end has a length in the direction, and
the cam second end length is greater than the first width.
11. The housing of claim 10 , wherein the cam is configured such that the cam second end passes through the opening second portion when the cam moves from the first orientation to the second orientation.
12. The housing of claim 11 , wherein the first panel has an inner side facing a housing interior and an outer side opposite the inner side and wherein the cam second end overlies the first panel outer side when the cam is in the second orientation.
13. The housing of claim 12 , where the door free end contacts the first panel when the door is in the first position.
14. The housing of claim 12 , wherein the cylinder is key actuated.
15. The housing of claim 11 , wherein the first panel has an inner side facing a housing interior and an outer side opposite the inner side and wherein when the cam is in the second orientation, the cam second end has a first section overlying the first panel outer side and a second section overlying the opening second portion.
16. The housing of claim 10 including first and second brackets configured for supporting the housing in a rack.
17. The housing of claim 16 , wherein the housing comprises an optical fiber shelf.
18. A housing comprising:
a first panel lying in a first plane and having an inner side facing into the housing and an outer side opposite the inner side, a first edge and an opening having a side wall extending through the first panel and having a continuous periphery spaced from the first edge, the opening including a first portion having a first width in a direction perpendicular to the first edge and a second portion having a second width in the direction, the second width being greater than the first width,
a second panel parallel to and spaced from the first panel;
a door having a hinge edge hingedly connected to the second panel and a free edge opposite the hinge edge, the door being shiftable between a first position with the free edge in contact with the first panel and a second position with the free edge spaced from the first panel;
a lock mounted on the door, the lock comprising a key actuated rotatable cylinder having an axis of rotation perpendicular to the door and a cam having a first end connected to the cylinder for rotation with the cylinder and a second end spaced from the first end by a cam body, the second end extending at an angle to the cam body and lying in a second plane parallel to the axis of rotation and having a length in the direction greater than the first width;
