Abstract: The present invention relates to a scaffold deck of simplified construction. The scaffold deck has two parallel side rails connected at the ends by means of parallel transom members. Hook members are provided at the junction of the transom and side rail members with the fasteners for each hook member commonly securing the respective transom and side rail. The side rails at the opposed interior edges include a substrate engaging slot extending in the length of the side rails and have an edge region beyond the substrate which forms part of the top working surface of the scaffold deck. The scaffold deck advantageously uses the side rails for forming an edge region of the scaffold deck whereby the amount of substrate between the side rails is reduced thereby reducing cost and improving the weight of the scaffold deck.

Abstract: This is a trestle support bracket comprised of a main member referred to as a bracket housing, which is coupled to the trestle cross-beam and a second member, referred to as the wedge.

Abstract: This invention is a tray that attaches to the side of hollow-rung ladders. The tray is sized large enough to accommodate an industry standard paint-roller-pan and hold it in a convenient position for the user either at the left side or at the right side of the ladder. The tray mounts to the ladder via a shaft that passes thru one hollow-rung. Secure attachment to various width ladders is accomplished via a safety-clip inserted into one of the series of thru-holes in the free end of the shaft that extends thru the hollow-rung. Adjustment of the tray to horizontal is accomplished via a movable L-shaped support that penetrates into a second hollow-rung. This invention contains fewer and simpler parts in comparison to prior inventions.
