FAQ
Frequently Asked Questions
Find quick answers to the most common questions about our products, services, and processes.
What is a NEMA enclosure rating?
NEMA ratings indicate how well an enclosure protects against dust, water, and other environmental factors. We can fabricate enclosures to meet specific NEMA rating requirements based on where your equipment will be installed.
Can you build enclosures to IP65 or IP67 standards?
Yes, we fabricate enclosures to meet IP65, IP67, and similar ingress protection standards. Share your required rating and we'll confirm feasibility for your design.
Do you provide junction boxes as part of a larger enclosure order?
Yes, junction boxes can be fabricated alongside your enclosure order, either as standalone components or integrated into a larger assembly.
