Plastic switch cups are used to fasten toggle switches in RVs, Toy Haulers and Horse Trailers. Sierra Pacific Engineering and Products manufactures switch cups using durable plastic material that is long-lasting due to the addition of UV inhibitors. This additional protection helps prevent the degradation of the plastic when exposed to the sun’s UV rays and salt air. In addition, the surface of the cups has light texture that makes it scratch-resistant.  SPEP’s  competitively priced plastic switch cup includes up to four punch holes, allowing customers to only punch out the number of holes they need with respect to the amount of toggle switches they have.

A strap hinge is a type of hinge that is quite simple yet effective. It is generally made up of two leaves or flaps or one leaf and a butt.  One long flat leaf is fastened to the face of a door or a lid while the much shorter leaf or butt is attached to a stationary surface adjacent to the lid or door. The thickness of the leaf as well as its design allows the hinge to be both durable and reliable. Strap hinges come in different styles and sizes; they also come in different types of materials and finishes to fit various user applications and industries. Strap hinges can be used for aesthetic purposes or light duty use such as on a metal box for outdoor usage. These hinges can also be used for holding large gates and doors as well as in outfitting trucks and trailers. These particular hinges come with deep counter sunk holes so screws sit flush for a clean look after attachment.


Stainless steel strap hinges provide longevity, durability, and aesthetics. The material prevents corrosion even in marine or moist environments, which enables the hinge’s appearance and function to remain unaffected even when exposed to salt water. The material tends to be stronger than most which provides users with long-lasting reliability. The brushed finish on the hinge allows it to look great on whatever door it is fastened to. Though stainless steel strap hinges can be used in a variety of ways, this type of hinge is often purchased by customers who wish to use it on high end trailers and trucks for both its reliability and beauty.
