When Standard Enclosures Just Won’t Cut It

Not every electrical installation happens in a climate-controlled room. Some jobs are exposed to the worst nature has to offer — relentless humidity, corrosive salt air, and the punishing Florida sun. That’s exactly the situation one homeowner faced when wiring a private dock in Nokomis, Florida: they needed a custom PVC trough enclosure tough enough to protect wiring in a harsh saltwater environment, and nothing on the market seemed to fit the bill.

After researching his options, the customer found Qube — and discovered that not all PVC enclosures are created equal.

The Project: Dock Wiring in a Saltwater Environment

The customer needed to protect a large number of wires running beneath a dock directly exposed to ocean salt spray. The project was permitted through Sarasota County and required materials that could reliably stand up to a marine environment for years to come.

Having already dealt with the headaches of metal hardware on another dock, the homeowner knew the answer wasn’t steel or aluminum. The search was on for a non-metallic enclosure with real structural integrity.

“Having experience with electrical equipment on another dock we own, the best material to use is non-metallic construction due to the salt spray. Anything metal presents long-term integrity issues and equipment grounding concerns.”
— Customer, Retired Master Electrician, Nokomis, FL

Why Chose Qube: Superior Construction for Marine Applications

After researching PVC enclosures from multiple suppliers, the customer selected Qube’s TR080848 PVC electrical trough enclosure. The reason? Superior construction — specifically the quality of the material and the wall thickness compared to other options on the market.

For a saltwater dock installation, those details matter enormously. Here’s why Qube’s PVC enclosures are the right call for harsh marine environments:

  • Corrosion-resistant: High-performance PVC will never rust, pit, or degrade from salt exposure the way metal enclosures will.
  • No grounding concerns: Non-metallic construction eliminates the equipment grounding issues that arise with metal in marine settings.
  • Thick, durable walls: Qube enclosures are built with wall thickness that outlasts thinner, cheaper alternatives.
  • Weather and UV resistant: Designed to withstand extreme environmental conditions, including Florida’s intense sun, humidity, and coastal salt air.
  • Less long-term maintenance: Enclosed equipment requires less upkeep when properly protected by a Qube enclosure.

Fully Customizable to Fit Your Exact Application

One of Qube’s greatest strengths is customization. Whether your equipment is an unusual size, requires wall or table mounting, needs multiple door access points with locks, or has to fit in a tight or unconventional space — Qube can build it. Some units can even be fabricated to hold multiple pieces of equipment, such as a computer and printer in a single enclosure.

All Qube enclosures are produced using CAD-CAM technology, which ensures 100% accuracy and a product appearance similar to injection-molded parts — without requiring large production runs or expensive tooling and die setups. That makes custom orders both practical and affordable.
