Plastic hinges by Sierra Pacific Engineering and Products are manufactured from a heavy duty polymer, which makes them much lighter in weight than steel hinges. The plastic material is also non-conducting and impervious to corrosion in harsh environments. As a result, plastic hinges are useful for many applications in the marine, electrical/electronic enclosure and truck/trailer industries.

SPEP offers a wide range of plastic hinges, including strap hinges, friction hinges, butt hinges, enclosure hinges, and lift-off (take apart) hinges. Our heavy duty plastic hinges come in black or white plastic, with stainless steel, zinc-plated steel or brass hardware.

We offer plastic butt hinges that come with plastic screw caps or bushings. Some come pre-drilled with countersunk holes for attachment with standard-sized screws. We also manufacture a line of plastic electronic enclosure hinges with stainless steel or brass studs, made with holes and/or hole inserts that create matched sets.

Our plastic strap hinges for marine applications, such as storage hatches and engine covers, resist rust and corrosion when exposed to saltwater and UV radiation.

If none of the plastic hinges in our catalog meet your specific requirements, Sierra Pacific’s team of experienced engineers can modify or create a completely new hinge design.

At SPEP, we take great pride in the quality of all of our products, and we earned the ISO 9001 quality certification in 2001. We rely on Oracle’s Quality Module, and our warehouses and shop floor are completely automated. All orders are quickly updated across the system as soon as they are received, enabling easy tracking for you.

We are also a 100% employee-owned company, which means each employee is committed to customer satisfaction. Contact us today for more information about our plastic hinges and other high quality industrial hardware.
