Abstract: A looped elastomeric strap is combined with a sinusoidal shaped snubbing clinch having a hook at one end to secure to an eyelet of a tarpaulin or to the free end of the looped strap. Parallel spaced bars are contiguously formed with the distal end of the hook to clinch and hold pairs of lays of the strap in non slip mode in the clinch.

Abstract: A pair of plates are interposed between the head of a screw means fastened through a roof covering and into a roof surface and truss therebelow. One plate is a lock nut composed of ratchet toothed means fixed to and facing downwards of the screw head and the second plate is a disc-shaped member fixed to the sheath of the roof covering and has ratchet teeth facing upwards and engageable with the teeth of the screw lock nut member when the screw is mated with the disc-shaped member.

Abstract: A weatherseal flashing is made from sheet vulcanized rubber and surrounds a skylight frame situate on a roof curb. The weatherseal consists of a plurality of sealedly lapping panels each embodying a relatively wide apron and an upstanding flange extending along one elongated edge of the rectangular-shaped panel. The ends of each panel flange have overlapping sealedly connected wings on their ends to provide collectively, a continuous fastener for surrounding the inner side or leg of the skylight assembly to make a co-planar seal in engagement with the combined projecting curb and the skylight frame, and the roof surface.
