Utility tray

A tray, capable of being frictionally engaged to a support structure, the tray comprising:

• a planar base extending in a horizontal plane and having an edge parallel to the support structure;
• a C-clamp coupled to a bottom surface of the planar base, comprising:
• a horizontally oriented side, a first portion of which abuts a bottom surface of the planar base, a second portion of which extends further in the horizontal plane from the edge of the base;
• a first vertically oriented side meeting the second portion of horizontally oriented side at a first corner of the C-clamp and extending downward;
• and
• a second vertically oriented side meeting, under the bottom surface of the planar base, the first portion of the horizontally oriented side at a second corner of the C-clamp and extending downward, the second vertically oriented side positioned a horizontal distance from the edge of the base and opposite the first vertically oriented side sufficient to receive the support structure positioned therebetween, the second vertically oriented side comprising a threaded hole;
• and
• a screw comprising a handle at a first end of the screw and a shoe at a second end of the screw, the second end of the screw passing through the threaded hole of the second vertically oriented side of the C-clamp and extending horizontally toward the first vertically oriented side of the C-clamp, wherein movement of the handle causes the second end of the screw to further extend horizontally toward the first vertically oriented side of the C-clamp such that the shoe and the first vertically oriented side of the C-clamp frictionally engage the support structure when the support structure is positioned between the first and second vertically oriented sides of the C-clamp.
