An extendible scaffold plank is composed of one plate slidably attached to another. Preferably the longitudinal edges 22 of the upper plate 20 fold around to enclose the longitudinal edges of the lower plate 30. There is ideally a semicircular cut-out 24, 34 at the distal ends of each plate to accommodate a vertical scaffold tube. The distal ends 32, 28 of the plates may also be folded to allow the lower plate of one plank to hook onto the upper plate of an adjacent plank. The plates may attach to an underlying board via screw holes. The plank is designed to span a gap which conventional planks cannot due to the position of the vertical poles. A kit of parts and a method of use of the apparatus are also claimed. |
