A structural fuse is disclosed including a fuse base and a fuse plate extending from the fuse base. The fuse plate may include a reduced diameter yield section configured to yield at loads on the structural fuse above a threshold. The reduced diameter yield section includes a pair of slots on either side of the yield section, which slots receive a pair of spacers. The spacers are integrally formed as part of the fuse plate, and remain attached to the fuse plate during fabrication of the structural fuse.

A one-piece structural fuse assembly is disclosed that is formed from a single piece of structural steel such as a beam. In embodiments, a first flange of the beam may form the fuse base, and a portion of the web of the beam may form the fuse plate. Additionally, a buckling restraint plate of the structural fuse assembly may be formed from a second flange of the beam, and the spacers of the structural fuse assembly may be formed from a portion of the web unused by the fuse plate. In examples, all of the components cut from the single piece of the beam are used in a single structural fuse assembly.

A removable ladder tray on a ladder having a base with a ladder opening formed therein. The ladder tray is attached and removed without tools. The ladder tray has an open containment area with a collared ladder opening for insertion of the ladder. The ladder opening is generally rectangular and formed adjacent the back of the tray. The ladder opening is surrounded by two spaced apart side edges and two spaced apart ladder leg edges forming a truncated pyramid shaped ladder box. The ladder tray press fits onto the ladder between the top of the ladder and the rungs. The ladder box surroundingly fits around the ladder holding the base top extending away from the user thereby allowing full use and access to the all the climbing rungs and the top platform on the ladder.

An anchor bolt locator is provided that is inexpensively manufactured on automatic die-press machines from sheet steel and a structural nut that does not require any welding, while also being easy to use and install with current, commonly-used building practices and anchor designs. The anchor bolt locator is made from a galvanized sheet metal chair and a structural nut attached to the chair by way of a friction fit.
