Buckles-Smith Assembly Services

You deserve more than just a supplier. Buckles-Smith can help you increase core operations to expand production and discover new avenues of opportunity. As part of our value-add offering, Buckles-Smith provides solutions to optimize your business and help you increase your margins. We offer assembly services, sub-assemblies, custom kitting, engraving and marking, custom label creation, and product software customization to help you keep up with demand. We go above and beyond to reduce your overhead costs and produce a higher margin for your business.

Why Use Our Value-Add Services?

  • Reduce dedicated inventory
  • Decrease purchasing time
  • Minimize labor for assembly parts selection
  • Shorten lead times
  • Simplify paperwork
  • Concentrate shop labor on final assembly
  • Faster time to market
  • Streamline supply chain


Like custom kitting, sub-assemblies save you labor by keeping your employees concentrated on getting your final product to your customers. Other benefits typically associated with sub-assemblies are less purchasing activity, amplified productivity, and lighter paperwork.

Spend less time managing orders by placing one order for one part number rather than multiple parts. Allow us to research and supply material for labor to reduce your time and effort searching for materials, processing administrative duties, and rectifying accounting discrepancies.

Types of jobs include, but are never limited to, wiring and wire harnessing, standard off-the-shelf part modifications, din-rail mount terminal block assembly, custom cord sets, and power quality systems.

Custom Kitting

Kitting is a crucial part of the supply chain process. If you use numerous electrical components regularly for a particular machine or assembly, let Buckles-Smith pre-package the materials for efficient inventory management and reduced labor costs.

Provide a list of components, and we will package the material from our inventory, complete with your internal part numbers. By limiting the total number of manufacturing steps, kitting saves time and money for your operation.

Kitting also improves workflow and material handling, lowers labor and related expenses, mitigates workplace risk and hazards, and reduces your storage requirements and warehouse space needs.

Engraving and Marking

We offer custom nameplates, legend plates, and push-button heads. Terminal block marking is available for all major lines, including Allen-Bradley, Wago, and Entrelec, with a two-day turnaround time.

Custom Labels and Lamination

Product-specific labels, including graphics, can be printed and applied to your devices to supply a turn-key product. Let Buckles-Smith handle your custom label and lamination needs. Contact our sales staff for details.

Product Software Customization

Product software customization is part of the value-add services we offer. We customize parameter settings for manufacturer products that are not factory standard. Customers use product software differently, and by customizing software to meet your needs, we're able to format features in ways that work for you. When you're satisfied, we've added value successfully. Customization typically applies to variable frequency drives and uninterruptible power supplies.

With variable frequency drives, some customers find programming and monitoring to be tedious. Customized software makes programming, monitoring, and troubleshooting much more manageable. The ability to eliminate the need to remember functions and values between devices can be invaluable. Streamlined variable frequency drive startup takes the guesswork out of programming. Customizing parameter settings and writing these settings to the drive eliminates your need to remember modifications.

In terms of uninterruptible power supplies, customized software can alert you when a battery needs replacement or cannot support your network requirements. Real-time monitoring is critical in reducing unplanned outages for 100% uptime. Customized alerts mitigate the risk of data loss in significant power failures. These alerts lead to faster resolution and get your networks back on track quickly.
