We now offer our Shoulder Eye Bolts at very competitive prices!!    All sizes are in stock and ready to ship.

Shoulder Eye Bolts are used in vertical as well as angular lifts. The shoulder feature of these eyebolts provides more stability when lifting loads, keeping the shank of the eyebolt from rocking particularly when the load is heavy. Sierra Pacific Engineering and Products offers a large selection of eyebolts with shoulders which come in multiple sizes to suit our every customer’s needs. Each size is load-rated based on straight vertical lift. It is important to note that the rated capacity of eye bolts is substantially reduced when loading at an angle. Thus, loading must never be made at an angle that is greater than 45 degrees from the bolt center line. Otherwise, the rated capacity is reduced to ¼ of the eye bolt rating.

To ensure Stainless Steel eye bolt’s durability when exposed to the elements such as rigging or marine environment and for a high luster finish, each SPEP Stainless Steel shoulder eye bolt is passivated and  electropolished.

Sierra Pacific Engineering and Products has a new L-handle (also known as a lever handle) and latch assembly specifically designed for trash chute and linen chute doors. Each L-handle assembly features a handle, V-spindle, and a tubular latch which has a spring loaded bolt. The assembly acts like a slam-action latch which makes it perfectly suited for use on self-closing doors. Our L-handle was designed for both comfort and longevity; it has a comfortable grip and a polished chrome plated finish.  We offer both key-locking and non-locking L-handles.

Most trash and linen chute doors are fitted with T-handles but SPEP’s L-handle assembly makes a chute door easier to open. Thus, our assembly is ideal as a replacement for chute door T-handles, complying with ADA standards.

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.

Cam Locks are one of the most popular and inexpensive items used to secure doors, windows, cabinets, lockers, drawers, safety boxes, and the like. This lock is made up of two parts: a cam and a base. The cam is a metal plate that is attached to the locking mechanism (the base).  A key or tool is inserted and turned in order to rotate the cam between 90 to 180 degrees, retracting or ejecting the metal plate which causes it to open or lock a door or lid.
