Abstract: A hurricane tie fastener and method are provided for securing a truss to a wall structural member. The fastener includes upper and lower vertical perpendicular plates with respective nail-receiving through holes formed therein. A horizontal arm extends from adjacent the bottom of the upper plate away from the lower plate. A leg extends upwardly from the arm. A truss-receiving space is formed between the upper plate and leg having a top entrance opening for receiving the bottom of the truss when the fastener is moved upwardly relative to the truss. The fastener is self-supporting on the truss to make the nailing of the fastener to the truss and wall member easier and safer.

Abstract: A panel clip configured primarily for use in roofing defines lower and upper spaces for respectively receiving therein the edge of a first panel and the edge of a second panel to help maintain the two panels in a coplanar relationship. Specially configured teeth extend into the lower space to inhibit removal of the first panel from the lower space. The clips are typically used midway between the rafters of a roof to provide additional support to the panels.

Abstract: An improved downed water skier warning system for alerting the operator of a skier tow-boat and the operators of nearby boats when a skier falls into the water or releases the skier towrope. The system includes electronic water sensors for sensing when the rope-handle of the skier tow-rope lands in the water, and pressure sensors for sensing when the water skier releases the rope handle. The water and pressure sensors are in remote communication with audible and visual tow-boat operator alarms and visual "skier-down" warning indicators, for enabling said alarms and indicators when a "downed skier" situation occurs. The improved warning system is designed for use in conjunction with marine warning devices and indicators commonly available, such as the "skier-down" flag and bow or stem directional lights.
