The 239BK is a new over center latch offered by Sierra Pacific Engineering and Products. This new latch is made from glass reinforced plastic with UV additives and stainless steel hardware, making it ideal for most environments, even in situations where rust or corrosion are concerns. SPEP’s 239BK features concealed mounting, ensuring that only the latch’s black matte textured body is exposed once installed. This latch features an adjustable mounting force, achieved by simply moving the stainless steel lock nut up or down on the cap screw until the desired tension is reached. A keeper is also included with every latch.

Heavy duty magnetic catches are the perfect solution to keeping heavy doors closed when using a latch assembly isn’t an option. Magnetic catches offer a cleaner look than latch hardware without having to spend more than users are willing to. These magnetic catches are used in various industries and in many applications, including in cabinets, shutter doors, medicine cabinets, or in any situation that requires a higher strength magnet. Sierra Pacific Engineering and Products offers a variety of heavy duty magnetic catches that come in different sizes and types, some of which have a holding force up to 33lbs, and many are available with strike. Available options from SPEP include flush mountings, snap-ins (for fast & easy mounting that does not require the use of screws), and double plated magnetic catches (perfect for double doors that meet in the center such as cabinets for electronics). Heavy duty magnetic catches are available in different housing materials; plastic is available for an economy option, while die cast zinc is available for when a higher holding strength is a necessity. Sierra Pacific Engineering and Products also offers magnetic catches that are specifically designed for screw mounting on two different planes.

Light duty magnetic catches are a simple and unobtrusive alternative to latches in lightweight applications that require a holding force less than 1lb.

Sierra Pacific Engineering and Products offers various types of light duty magnetic catches, including custom options which enable us to meet any customer's needs. SPEP’s light duty magnetic catches are available with flush mountings for a sleek aesthetic, snap-in mountings for quick & easy installation, and dust proof magnetic catches for clean room environments.

We now offer 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.

Now also available in 316SS material.
Other materials also available in stock, such as forged steel, 304SS and forged steel with zinc plated finish.
