CANTEX

CANTEX is a North American manufacturer of PVC and nonmetallic electrical enclosures, fittings, and accessories, with a product line that spans electrical boxes, weatherproof covers, floor boxes, and conduit support components. The company’s catalog is built around injection-molded PVC and other nonmetallic materials, offering alternatives to metal enclosures in applications where corrosion resistance, dielectric properties, or weight reduction are priorities. CANTEX products are designed to meet UL standards, as indicated by the UL listing on items such as conduit strap clamps (SKU 4FYU3, 4FYU1, 4FYT5, 4FYT7). The product range includes cut-in electrical boxes (e.g., MPN EZ21SOR) for retrofit installations, standard square and rectangular boxes (e.g., MPN EZ32XNR) for new construction, and weatherproof covers (e.g., MPN 5133331) for outdoor FS-series enclosures. Floor box bases (e.g., MPN 5133760) provide in-floor power and data access points with capacities up to 90 cubic inches. Conduit and pipe strap clamps in trade sizes from 1/2 in to 3 in accommodate PVC Schedule 40 and 80 conduit systems. CANTEX components are typically gray in color, reflecting the standard UV-stabilized PVC formulation used for electrical enclosures. The brand does not manufacture metallic boxes or fittings; its focus is exclusively on nonmetallic solutions for residential, commercial, and light industrial electrical installations. 3G Electric supplies CANTEX products globally, offering over 87 SKUs that cover the primary product families: cut-in boxes, standard boxes, weatherproof covers, floor boxes, and conduit clamps. For plant engineers and maintenance managers, CANTEX products are relevant in environments where metal enclosures would corrode—such as wastewater treatment, chemical processing, or coastal facilities—or where nonconductive materials are required for safety. The PVC construction provides inherent resistance to moisture, chemicals, and UV exposure, reducing maintenance frequency in outdoor or harsh indoor settings. Procurement specialists can source CANTEX items individually or in bulk through 3G Electric, with specifications including box dimensions, gang counts, clamp styles (NMSC), bracket styles (flush or without bracket), and conduit trade sizes. The product data sheets provide dimensional and capacity details necessary for code-compliant installations. CANTEX does not produce metallic components, so buyers requiring steel or aluminum enclosures should look to other brands in the 3G Electric catalog.

Frequently asked questions

Common questions about CANTEX from 3G Electric.

What UL standards do CANTEX conduit strap clamps comply with?

CANTEX conduit strap clamps, such as SKU 4FYU3 (3 in trade size) and 4FYT5 (1/2 in trade size), are listed as meeting UL standards. The specific standard is UL 651 for rigid PVC conduit and fittings, which covers Schedule 40 and 80 conduit systems. These clamps are designed for use with PVC conduit and cable, providing secure two-hole mounting. The UL listing ensures the clamps have been tested for mechanical strength, UV resistance, and flame retardance as required for electrical installations in commercial and industrial settings.

Are CANTEX weatherproof covers compatible with metal FS boxes?

Yes, CANTEX weatherproof covers like MPN 5133331 are designed for use with FS series boxes, which are typically metal enclosures used for outdoor wiring devices. The cover is made of gray PVC and is rated for vertical mounting with toggle switches. It fits standard 2-gang FS boxes and provides a weatherproof seal when properly installed with gaskets (not included). The PVC material offers corrosion resistance, making it suitable for outdoor environments where metal covers might rust. Always verify the box dimensions and gasket compatibility before installation.

What is the difference between CANTEX cut-in boxes and standard boxes?

CANTEX cut-in boxes, such as MPN EZ21SOR, are designed for retrofit installations where the box is inserted into an existing wall opening. They feature a flush bracket style that secures the box to the drywall or plaster without requiring attachment to a stud. Standard boxes, like MPN EZ32XNR, are intended for new construction and are typically mounted to studs or joists using nails or screws. Cut-in boxes have NMSC clamps for nonmetallic sheathed cable, while standard boxes may come without brackets or with different clamp styles. Both are made of PVC and are UL listed for electrical use.

Can CANTEX floor box bases be used with concrete pours?

CANTEX floor box bases, such as MPN 5133760, are designed for in-floor installations, including concrete pours. The base is made of gray PVC and has a 90 cubic inch capacity, accommodating conduit sizes of 1/2 in and 3/4 in. It is sold as a box only (cover not included) and is intended for use with compatible floor box covers. The PVC material resists moisture and chemical attack from concrete, but the box must be properly sealed and leveled before pouring. Check local codes for floor box requirements in your jurisdiction.

What trade sizes of conduit do CANTEX strap clamps support?

CANTEX two-hole conduit strap clamps are available in trade sizes from 1/2 in (SKU 4FYT5) up to 3 in (SKU 4FYU3). Intermediate sizes include 1 in (SKU 4FYT7) and 2 in (SKU 4FYU1). All are made of gray PVC and are compatible with PVC Schedule 40 and 80 conduit. The clamps are UL listed for securing cable and conduit to surfaces. They feature two mounting holes for secure fastening and are suitable for indoor and outdoor use where PVC conduit is installed.
