Drilling explosion-proof cabinets

Drilling Explosion-Proof Cabinets. Explosion-proof enclosures feature cast walls up to 1½” thick, and they do not come with standard predrilled holes. If you want conduit entries drilled to your specifications you have two choices: Order them from the factory and wait six weeks, or drop them off at ACES where they’ll be ready in 24-48 hours. ACES is a UL 508A and UL 698A listed control panel builder, and the only shop in the area offering this service.

Our 60? radial-arm drill makes short work of entries and taps for buttons, switches and bolts in the thickest explosion-proof cabinets, with pin-point precision and perfectly aligned holes. When you pick them up they’ll be ready to receive your conduit and operators — right the first time.

When your cabinets are going into a volatile, explosion-prone environment you want nothing less than perfection. Download a .pdf with pricing schedule and more information or give us a call to talk about specs for drilling your explosion-proof cabinets.
