A scaffold plank assembly for engagement to a scaffolding frame. The scaffold plank assembly comprises an elongate, non-metal plank defining opposed first and second ends and at least one interior cavity. Attached to respective ones of the opposed ends of the plank is a pair of end connectors. Each of the end connectors comprises a main body defining an arcuate body engagement surface, and at least two arms which are attached to the main body. Each of the arms also defines an arcuate arm engagement surface which is substantially continuous with the body engagement surface. Attached to and extending from the main body is at least one attachment finger which is extensible into the interior cavity of the plank. The body and arm engagement surfaces are sized and configured to be cooperatively engageable to the scaffolding frame.

What is claimed is: 1. A scaffold plank assembly for engagement to a scaffolding frame, the scaffold plank assembly comprising: an elongate, non-metal plank defining opposed first and second ends; and a pair of end connectors attached to respective ones of the opposed ends of the plank, each of the end connectors comprising: a main body defining a pair of opposing lateral faces, an arcuate body engagement surface extending inwardly from each of the pair of opposing lateral faces, and a pair of engagement faces extending upwardly from the body engagement surface and inwardly from respective ones of the pair of opposing lateral faces; and at least two arms attached to the main body between the pair of engagement faces, each of the arms defining an arcuate arm engagement surface which is substantially continuous with the body engagement surface, the body and arm engagement surfaces being sized and configured to be cooperatively engageable to the scaffolding frame; the main body including at least two notches formed therein which each have a shape that is complementary to the arms, at least one of the notches being disposed between the arms for matingly receiving one of the arms of a similar adjacent end connector therein. 2. The scaffold plank assembly of claim 1 wherein each of the end connectors is fabricated from a non-metal material. 3. The scaffold plank assembly of claim 1 wherein each of the end connectors further comprises at least one locking clip attached to the main body and frictionally engageable to the scaffolding frame. 4. The scaffold plank assembly of claim 1 wherein each of the end connectors comprises an attachment portion which is integrally connected to the main body and cooperatively engageable the plank. 5. The scaffold plank of claim 4 wherein the attachment portion comprises at least one elongate attachment finger which is extensible into an interior cavity defined by the plank. 6. The scaffold plank of claim 5 wherein the attachment portion comprises a plurality of attachment fingers which extend in spaced, generally parallel relation to each other and are each extensible into the interior cavity of the plank. 7. The scaffold plank assembly of claim 1 wherein the plank is fabricated from a plastic material. 8. The scaffold plank assembly of claim 1 wherein the plank includes: an elongate, generally planar top wall defining inner and outer surfaces and opposed pairs of longitudinal and lateral sides; an elongate, generally planar bottom wall defining inner and outer surfaces and opposed pairs of longitudinal and lateral sides; an opposed pair of sidewalls integrally connected to the top and bottom walls and extending along respective pairs of the longitudinal sides of the top and bottom walls in generally parallel relation to each other; and a plurality of reinforcement walls integrally connected to and extending perpendicularly between the inner surfaces of the top and bottom walls and in spaced, generally parallel relation to each other and to the side walls. 9. The scaffold plank assembly of claim 8 wherein at least the outer surface of the top wall includes a textured pattern formed thereon. 10. The scaffold plank assembly of claim 8 wherein: the top wall, bottom wall, sidewalls, and reinforcement walls collectively define at least one interior cavity; and each of the end connectors comprises at least one elongate attachment finger which is extensible into the interior cavity of the plank. 11. The scaffold plank assembly of claim 10 wherein each end connector is attached to the plank through the use of at least one fastener which is advanced through each of the side walls of the plank and into the finger of the end connector. 12. The scaffold plank assembly of claim 1, wherein one of the at least two arms is disposed adjacent a first of the pair of engagement faces, and wherein one of the at least two notches is disposed adjacent a second of the pair of engagement faces. 13. An end connector for attachment to an elongate plank defining opposed first and second ends, the end connector being engageable to a scaffolding frame and comprising: a main body defining a pair of opposing lateral faces, an arcuate body engagement surface extending inwardly from each of the pair of opposing lateral faces and a pair of engagement faces extending upwardly from the body engagement surface and inwardly from respective ones of the pair of opposing lateral faces; and at least two arms attached to the main body between the pair of engagement faces, each of the arms defining an arcuate arm engagement surface which is substantially continuous with the body engagement surface, the body and arm engagement surfaces being sized and configured to be cooperatively engageable to the scaffolding frame; the main body including at least two notches formed therein which each have a shape that is complementary to the arms, at least one of the notches being disposed between the arms for matingly receiving one of the arms of a similar adjacent end connector therein, the at least two arms and the at least two notches collectively forming a generally sinusoidally shaped connector sidewall. 14. The end connector of claim 13 wherein the end connector is fabricated from a non-metal material. 15. The end connector of claim 14 wherein the end connector further comprises an internal metallic reinforcement plate which extends at least partially within the main body and arms thereof. 16. The end connector of claim 13 wherein the end connector further comprises at least one locking clip attached to the main body and frictionally engageable to the scaffolding frame. 17. The scaffold plank assembly of claim 13 wherein the end connector comprises an attachment portion which is integrally connected to the main body and cooperatively engageable the plank. 18. The scaffold plank of claim 17 wherein the attachment portion comprises at least one elongate attachment finger which is extensible into an interior cavity defined by the plank. 19. The scaffold plank of claim 18 wherein the attachment portion comprises a plurality of attachment fingers which extend in spaced, generally parallel relation to each other and are each extensible into the interior cavity of the plank. 20. A scaffold plank assembly for engagement to a scaffolding frame, the scaffold plank assembly comprising: an elongate, non-metal plank defining opposed first and second ends; and a pair of end connectors attached to respective ones of the opposed ends of the plank, each of the end connectors comprising: a main body defining a pair of opposing lateral faces, an arcuate body engagement surface, and a pair of engagement faces extending upwardly from the body engagement surface and inwardly from respective ones of the pair of opposing lateral faces; at least two arms attached to the main body between the pair of engagement faces, each of the arms defining an arcuate arm engagement surface which is substantially continuous with the body engagement surface, the body and arm engagement surfaces being sized and configured to be cooperatively engageable to the scaffolding frame; and means for facilitating the attachment of the main body to the scaffold plank; the main body including at least two notches formed therein which each have a shape that is complementary to the arms, at least one of the notches being disposed between the arms for matingly receiving one of the arms of a similar adjacent end connector therein.
