Allied Molded Products — Nonmetallic Boxes, Fixture Supports and Enclosures for Electrical Contractors

Allied Molded Products (often shown as Allied Moulded on manufacturer materials) manufactures nonmetallic electrical boxes, fixture outlet boxes and enclosures. The company specializes in molded fiberglass‑reinforced polyester, polycarbonate and thermoplastic/PVC solutions used in residential, commercial and industrial electrical work.

What the brand is known for

Allied is known for its FiberglassBOX™ and flexBOX® product families: durable switch and outlet boxes, round ceiling fixture boxes and fan/fixture support boxes, plus a range of industrial enclosures. Common features include machine‑tapped fixture holes, Speed Klamps or factory clamp options and multiple gang/depth configurations.

Main product families and technologies

• Switch/receptacle boxes — single‑gang to multi‑gang in thermoplastic, PVC and FRP; nail‑on, old‑work and gangable designs (examples: P‑241, 4300/4304 series).
• Round ceiling & fixture boxes — 3.5" and 4" round FRP boxes with fixture mounting patterns (9300 series).
• Fan & fixture support — reinforced support boxes with listed fixture load ratings (e.g., 9351 series).
• Industrial enclosures — fiberglass and polycarbonate NEMA‑style enclosures, including NEMA 4X corrosion/UV resistant options.
• Accessories — divider plates, snap brackets, speed clamps and low‑voltage inserts.

Common applications

Allied products are widely used by electricians, contractors, facilities teams and OEMs for new work and retrofit installations, lighting and fan supports, junction and splice locations, and control enclosures where nonmetallic construction or corrosion/UV resistance is required.

Model identification — what to verify

When sourcing or replacing parts, confirm:

• Full catalog number including suffix (for example, 4304‑NK or 9338‑ESK).
• Material family (fiberglass, polycarbonate, PVC) and the box’s cubic‑inch capacity.
• Mounting type (nail‑on, old‑work, bar‑mount) and device mounting pattern.
• Cable entry style (Speed Klamps vs. knockouts) and included accessories.
• Listed approvals and fixture weight ratings on the product datasheet.

How Safsale helps procurement buyers

Safsale listings include filterable categories, high‑resolution images, downloadable datasheets and catalog PDFs, manufacturer catalog numbers and package quantities. These details help buyers confirm fit, approvals and accessory compatibility before ordering. Where available, user Q&A and reviews add installation context useful for replacement decisions.

Sourcing and replacement tips

• Specify the full Allied catalog number and suffix on RFQs and POs.
• Compare cubic‑inch capacity and mounting holes when fitting behind existing devices or fixtures.
• Confirm fixture/fan load ratings for ceiling boxes before replacing hardware.
• For alternatives, match material, capacity and device patterns; request photos or samples when interchangeability affects fit.
• For project purchasing, include standard package quantities and request lead‑time confirmation—do not assume immediate stock.
