Abstract: A protective insert for protecting wires and other contents of a utility box such as an electrical or communication wiring box, from damage during construction, particularly when cutting openings for such boxes in wallboard that has been placed onto studs. The insert is made to utilize the only standard dimensions in utility boxes, namely, the distance between the threaded bores used for fastening switches, receptacles or other fixtures. The protective insert is easily placed into utility boxes using two ribbed posts or shanks that fit into the openings of the box with a fit that retains the insert in place. The insert is easily removed, and it also protects the threaded bores in the box that are used for supporting switches, receptacles, light fixtures, or the like.

Abstract: A step support used in the construction of a staircase that can be attached to a stringer and is capable of securely supporting a step. The apparatus comprises a relatively thin first side member, a relatively thin second side member and a filler block. The filler block is smaller than the first and second side members and is attached between them so that there is a gap between the first side member and the second side member. The step support is attached to the stringer so that the stringer fits in the gap and the side members extend over the sides of the stringer. The step support is attached to the stringer through the use of a plurality of fasteners.
