The GREENFIELD 603-1 is a PVC-coated two-hole pipe strap designed for secure support of 1-inch conduit or tubing in electrical and mechanical installations. Fabricated from steel with a full PVC encapsulation, the strap delivers corrosion resistance and basic electrical insulation suitable for both indoor and outdoor environments. Its U-shaped body seats the conduit firmly while two mounting holes allow direct fastening to walls, ceilings, or structural framing members. Electricians and mechanical contractors install this fitting as part of a compliant conduit support system wherever code requires periodic fastening of rigid or flexible raceway runs.
This strap is sized for 1-inch conduit or tubing and fits standard residential and light commercial electrical installations. The two-hole design distributes load across two fastener points, reducing movement and vibration along the conduit run. The PVC coating guards against abrasion at the contact point between the strap and the pipe or conduit wall, making it a practical choice in damp, wet, or corrosive-adjacent locations.
Designed as a standard replacement and new-installation fitting for 1-inch rigid metal conduit, intermediate metal conduit, and similarly sized tubing runs in residential and light commercial electrical raceway systems.
Installation is performed by licensed electricians in accordance with applicable NEC requirements for conduit support spacing. De-energize all circuits in the work area before mounting straps on any existing conduit run. Fasten through both mounting holes using appropriately rated anchors or screws for the substrate material. Do not over-torque fasteners, as this can deform the PVC coating and compromise the strap's grip on the conduit.
