66 that are raised above the panel members 50 by a distance b inside edges of the beam members above the deck surface 55 forming respective edge barriers 68 for safely confining objects within the deck surface 55 an optional yet important feature of the present invention is that the bed 12 is provided with a spaced plurality of inclined socket members 70 for receiving respective yoke stems 71 of fixtures such as lighting fixtures 72 as shown in fig3 the inclination of the socket members 70 facilitates placement of fixture heads 73 laterally outside of the column members 16 and handrails 15 that may extend therebetween thus the handrails 15 do not interfere with light transmission from the fixture heads 73 to stage sets being illuminated thereby further the socket members 70 support the fixtures 72 out of the way of grip personnel that may be on the deck surface 54 more particularly the socket members 70 are preferably located proximate the beam members 56 each having a cylindrical opening 74 therethrough on a socket axis 75 the socket axis 75 being inclined outwardly at a socket angle u03c6 relative to the side edge 51 as shown in fig2 typically the socket axis 75 is normal to the deck surface 54 in a direction parallel to the beam members 56 as shown in fig4 however it is contemplated within the present invention that the axis 75 can be inclined both laterally and longitudinally or longitudinally alone relative to the scaffold bed 12 as further shown in the drawings the socket member 70 has a sleeve portion 76 that extends through the panel member 50 and.
