A poke-through device for installation in a hole in a floor structure. The floor structure defined by a floor in a first working environment and a ceiling in a second working environment. The poke-through device includes a basket, thermal barrier, lower plate and at least one coupling member. The basket including a coupling support surface. The thermal barrier being disposed below the basket. The lower plate supporting the thermal barrier. Also, the at least one coupling member extending through the thermal barrier and securing the basket to the lower plate. The coupling member including an upper portion disposed within the basket. The upper portion including an undersurface, wherein a first portion of the undersurface is in direct contact with the support surface and a second portion of the undersurface does not directly engage the basket.

What is claimed is: 1. A poke-through device for installation in a hole in a floor structure, the floor structure defining a floor in a first working environment and a ceiling in a second working environment, the poke-through device comprising: a basket, a lower structure of the basket including a coupling standoff mount having a support structure, the standoff mount having a contact surface located generally at the top of the support structure and a gap in the support structure for minimizing thermal transfer between at least one coupling member and the basket; an intumescent member disposed below the basket; a lower plate supporting the intumescent member; and the at least one coupling member extending through the intumescent member and securing the basket to the lower plate, wherein a first portion of the coupling member is in direct engagement with the contact surface and a second portion of the coupling member extends across the gap. 2. The poke-through device as set forth in claim 1, wherein the coupling member includes a head on at least one end and a dispersion plate disposed between the head and the contact surface. 3. The poke-through device as set forth in claim 2, wherein the dispersion plate is formed of a ceramic-fiber washer. 4. The poke-through device as set forth in claim 3, wherein the standoff mount includes a tab for holding the dispersion plate in a pre-selected position. 5. The poke-through device as set forth in claim 2, wherein the basket includes ribs that interlock with the dispersion plate for positioning the dispersion plate in relation to the basket. 6. The poke-through device as set forth in claim 1, wherein the coupling standoff mount integrally formed with the basket. 7. The poke-through device as set forth in claim 6, wherein the standoff mount protrudes upwardly from the lower structure toward the first working environment. 8. The poke-through device as set forth in claim 6, wherein the standoff mount protrudes inwardly from an outer portion of the basket. 9. The poke-through device as set forth in claim 1, further comprising an additional intumescent member disposed at least partially above the coupling member. 10. The poke-through device as set forth in claim 1, wherein the dispersion plate is an annular washer. 11. The poke-through device as set forth in claim 1, wherein the dispersion plate is sized to conform to at least a portion of an inner peripheral surface of the basket. 12. A poke-through device for installation in a hole in a floor structure, the floor structure defining a floor in a first working environment and a ceiling in a second working environment, the hole communicating between the first and second working environments, the poke-through device comprising: a receptacle-receiving basket, the basket including a lower structure having a coupling standoff mount, the standoff mount having a support structure including a contact surface generally at the top of the support structure and at least one gap in the support structure minimizing thermal transfer between at least one fastener assembly and the basket; an intumescent member disposed below the basket; a base member for supporting the intumescent member; and the at least one fastener assembly extending through the intumescent member and securing the intumescent member between the basket and the base member, wherein a first portion of the fastener assembly is in direct engagement with the contact surface and a second portion of the fastener assembly extends across the gap. 13. The poke-through device as set forth in claim 12, wherein the fastener assembly includes a bolt having a head and a dispersion plate disposed between the head and the contact surface. 14. The poke-through device as set forth in claim 13, wherein the standoff mount includes a tab for holding the dispersion plate in a pre-selected position. 15. The poke-through device as set forth in claim 13, wherein the basket includes ribs that interlock with the dispersion plate for positioning the dispersion plate in relation to the basket. 16. The poke-through device as set forth in claim 12, wherein the standoff mount includes an upper surface for engaging the fastener assembly first portion. 17. The poke-through device as set forth in claim 16, wherein the standoff mount protrudes upwardly toward the first working environment from the lower structure. 18. The poke-through device as set forth in claim 16, wherein the standoff mount protrudes inwardly from an outer portion of the basket. 19. The poke-through device as set forth in claim 12, further comprising an additional intumescent member disposed at least partially above the fastener assembly. 20. The poke-through device as set forth in claim 12, wherein the dispersion plate is an annular member.
