We Can Make Your Ideas Come to Life

Custom Controls  –  One-Off  –  Volume


We can manufacture custom assemblies or reproduce assemblies of any size. This can include panel assemblies and individual component assemblies.

A panel assembly would be any size panel that is duplicated and repeated. We dedicate an assembly area specific for the project including a location for stock hardware and supplies.

Types of component assemblies we have done are small motors with pigtails wired to a connector, or a valve assembly pre-wire to a terminal strip.

A component assembly can be any product that needs modifications to suit your requirements. For any assembly, we will track not only the hardware that we stock but also any components that you may supply.

In addition, we will maintain records for assembly purposes such as notes, markups, written procedures, example photos and testing. We will also provide bulk order tracking history or individual assembly tracking.

Cable Assemblies

We routinely manufacture wiring harnesses and cable assemblies for the controls systems we build. Additionally, we can build custom cable assemblies for other applications.

We offer assemblies that require crimping or soldering using various types of wire and cables. We cannot offer custom cables that require molded or specialty made ends like a HDMI, but we can cover most industrial applications.

We offer the same procedures for our cable assemblies as we do for our panel assemblies for maintaining records for assembly purposes, such as notes, markups, written procedures, example photos, testing and bulk order tracking history or individual assembly tracking.

Control Panel Layouts

Once a control system enters the manufacturing stage, one of the first procedures is the panel layout. Most commonly, the panel layout design is done at the engineering stage; however, there are times when there is no designed layout provided. Even if an engineered layout was done, prior to doing any cutouts or drilling, the components are laid out to verify everything fits as desired.

Other things that are evaluated are the weight, depth, thermal dissipation, swing radius of components, voltage separation and how to wire.

If no pre-engineered layout is provided, we use our experience to do an on-the-spot panel layout based on the products, schematics, and various code guidelines.

An as-built panel layout can be provided by our engineering team after the fact if desired. As an area often overlooked, we take panel layouts seriously to help ensure the best quality, functionality, distribution and look possible.

Control Panel Wiring

Along with good wiring practices we wire systems using wire or cable for digital, analog, high voltage and low voltage applications. We offer many different types of wire, termination types and wire labeling.

While our standard hookup wire is (UL1015) Stranded tinned copper,-40deg C to +105deg C, MTW, UL VW-1 Flame test, 600 volt rated, we are accustomed to using various types of wire such as MTW, teflon, SIS, thermocouple, multiconductor, shielded and many others. We generally use bare wire compression terminations, but also offer various options such as fork, ring, pin, ferrules and spade connections.

When it comes to labeling, our standard practice are heat shrink labels which provide good quality label reducing the chance of falling off, unraveling or becoming non-legible. We can also offer and use other labeling styles such as adhesive wrap around labels and or any other method you prefer.

In addition to termination and labeling we consider wire routing for signal isolation, high/low voltage segregation and flexibility for moving bundles.

Enclosure Modifications

We customize standard enclosures with cutouts, knockouts and other modifications to suit the application. Our experience is broad because on a regular basis, we deal with many materials such as steel, stainless steel, aluminum, plastics, and polycarbonates. Modifications to these may be as simple as drilling and tapping, doing hole knockouts, or more advanced custom cutouts. When providing these customizations, we will review your NEMA and IP rating requirements, and will consider gasket and mounting techniques to maintain the proper environmental ratings. Customizing an enclosure can go a lot further with RASP.

Inside the enclosure, modifications may include installing custom panels, swing panels, various depth panels, back-to-back panels, or side panels. We can add custom brackets to support large wire bundles, or to add devices such as coolers or purge systems. If you require seismic-rated enclosures, we can install properly zoned kits. We also work with local fabrication shops for more advanced customization, such as a complete custom cabinet or drilling and tapping an explosion-rated cabinet.

The list of customization options goes on and on, so if you have a unique application, just discuss it with us and we will help formulate a solution.

Hazardous Area Enclosures

By utilizing our experience with ATEX, IECEx, UL for hazardous area panel design and purge systems we can properly build systems for hazardous locations. We are accustomed to building systems required for hazardous areas using stainless steel enclosures, explosion-proof enclosures, and purged enclosures.

By utilizing our standard shop practices for building UL and hazardous area enclosures our panel assemblers are trained in building systems that meet strict design standards. From drilling and tapping explosion proof enclosures to providing the proper potting and sealing requirements we can meet your hazardous area assembly requirements.


We provide assembly and plumbing of pneumatic systems including valves, filters, regulators, flow controls, cylinders, purge systems and many other pneumatics components. If your design requires pneumatics to be assembled and plumbing to be done, we routinely work with these components.

From adding a simple valve to a control panel to building a complete pneumatic panel assembly, we have the experience. We work with different types of tubing, various styles of fittings and many wiring techniques.

Tubing runs may consist of many kinds of materials such as polyurethane, nylon or PTFE. We also do bending and running of solid stainless steel tubing. The same goes for fittings – we use various types of plastic, brass and stainless steel fittings in metric, NPT and o-ring styles. We are also accustomed to wiring many types of pneumatic connectors, such as PG9, PG11, molded in wire and conduit wire connections.

Purge Enclosures

Building a system with the proper Purge & Pressurization System allows for the safe use of systems in hazardous areas. We routinely assemble and build purged enclosures from either pre-designed purge systems or from a system designed by our team. We have built numerous purge system enclosures for various types of hazardous locations.

In addition, we can build and provide provide a UL certification for hazardous locations beyond the standard 508A based on the following classifications:

  • Type X Purge. For use in Class I, Division 1, Groups A, B, C and D Hazardous locations.
  • Explosion-Proof. For use in Class I, Division 1, Groups B, C and D Hazardous locations.
  • Type Z Purge. For use in Class I, Division 2, Groups A, B, C and D Hazardous locations.
  • Nonincendive. For use in Class I, Division 2, Groups A, B, C and D Hazardous locations.

RASP Incorporated’s commitment to our customers for their manufacturing needs is to provide on time delivery while maintaining a high standard of quality.
