A LOWER-PROFILE CHANNEL FOR COMPACT SUPPORT LAYOUTS.

The 41 × 21 mm strut-channel range provides a shallower profile for support layouts that do not require a full 41 × 41 mm section. Buyers can select the VK-4121 slotted version or the VK-4121P plain version.

The VK-4121 slotted channel uses confirmed 14 × 28 mm slots at a 50 mm pitch. Any section parameters documented specifically for VK-4121 should remain associated with that model and should not automatically be transferred to the plain VK-4121P version.

41 × 21 mm nominal section provides a lower-profile channel format.
Plain and slotted options are provided by VK-4121P and VK-4121 respectively.
14 × 28 mm slots are documented for the VK-4121 slotted channel.
50 mm slot pitch provides the confirmed spacing pattern for VK-4121.

Approximate theoretical weights are calculated using a 97 mm developed strip width and a steel density of 7,850 kg/m³. Slotted-channel calculations assume approximately 60 obround slots per 3 m length. Actual finished weight may vary with dimensional tolerances, bend radii, slot quantity and surface treatment. Please confirm production weight before ordering.

Electrical Metallic Tubing

Electrical Metallic Tubing Velkor manufactures Electrical Metallic Tubing (EMT) for commercial, industrial, and residential electrical installations. Every conduit is produced from premium low-carbon steel, delivering smooth bending performance, dimensional consistency, and dependable installation efficiency. Whether you need a cost-effective standard solution or maximum corrosion protection for demanding environments, Velkor offers the right zinc coating option for your project.

EMT Connector – Set Screw Type – Zinc Die Cast

EMT Connector – Set Screw Type – Zinc Die Cast Velkor set-screw EMT connectors are die-cast from virgin zinc alloy rather than lower-grade recycled material. Maintaining a controlled alloy composition helps reduce brittleness and the risk of cracking, giving the fitting greater toughness during installation, handling and transport.

EMT Coupling – Set Screw Type – Zinc Die Cast

EMT Coupling – Set Screw Type – Zinc Die Cast Velkor zinc die-cast set-screw EMT couplings join two lengths of EMT in a straight run. Each conduit end is secured independently by its own set screw, while the one-piece zinc alloy body supports consistent dimensions and straightforward installation.

EMT Connector – Compression Type – Zinc Die Cast

EMT Connector – Compression Type – Zinc Die Cast This zinc die-cast compression connector terminates EMT conduit at an electrical box, cabinet, or enclosure. Its compression nut applies circumferential clamping around the conduit for controlled alignment, while the one-piece zinc alloy body offers dimensional consistency and a clean installation profile.

EMT Coupling – Compression Type – Zinc Die Cast

EMT Coupling – Compression Type – Zinc Die Cast Velkor zinc die-cast compression EMT couplings join two lengths of EMT using independently tightened compression nuts. The compression mechanism grips around each conduit end to support alignment without exposed set screws, while the zinc die-cast body provides a clean, compact profile.

EMT Connector – Set Screw Type – Steel

EMT Connector – Set Screw Type – Steel Designed to connect EMT conduit securely to electrical boxes and enclosures through knockout openings. Manufactured from durable steel with a zinc-plated finish for corrosion protection. The set-screw design allows quick installation and provides a secure connection in dry locations.

Intermediate Metal Conduit

Intermediate Metal Conduit Velkor Intermediate Metal Conduit (IMC) provides greater wall strength and mechanical protection than EMT while remaining lighter than conventional rigid metal conduit. Three product configurations allow buyers to select the appropriate wall thickness, zinc coating and standard compliance for their market, project and budget.

Rigid Metal Conduit – Hot-Dip Galvanized Steel

Rigid Metal Conduit – Hot-Dip Galvanized Steel Velkor Rigid Metal Conduit is a heavy-wall steel raceway for installations that require greater mechanical protection than lighter metallic conduit systems. Each cataloged 3050 mm length is threaded for use with a rigid conduit coupling and supplied-end protection should be confirmed with the order specification.

RIGID 90 Degree Radius Elbow – Galvanized Steel

RIGID 90 Degree Radius Elbow – Galvanized Steel Velkor RIGID 90 degree radius elbows redirect threaded RIGID or IMC conduit runs through a right-angle bend. The galvanized steel body provides a formed metal pathway for changing direction within the threaded raceway system.

RIGID Coupling – Tubular Threaded – Galvanized Steel

RIGID Coupling – Tubular Threaded – Galvanized Steel Velkor tubular threaded RIGID couplings join two threaded RMC or IMC lengths to maintain raceway continuity. The galvanized steel body provides a direct threaded connection.

RIGID Strap – Two Hole – Galvanized Steel

RIGID Strap – Two Hole – Galvanized Steel Velkor two-hole RIGID straps support RIGID or IMC conduit against a mounting surface. A fastening point on each side of the conduit gives installers a balanced two-point attachment across the strap.

Rigid One-Hole Strap – Galvanized Steel

Rigid One-Hole Strap – Galvanized Steel Velkor rigid one-hole straps secure RMC or IMC to a mounting surface with one fastening point. The compact galvanized-steel profile is useful where installers need direct surface support without the wider footprint of a two-hole strap.

Flexible Metal Conduit – Greenfield

Flexible Metal Conduit – Greenfield Velkor Greenfield Flexible Metal Conduit provides flexible and reliable cable routing around equipment, machinery, and tight installation spaces. Its galvanized steel construction forms a continuous flexible raceway, making it suitable for applications where rigid conduit is difficult to route or install. Greenfield flexible conduit is also commonly referred to as American Standard Steel Flexible Conduit. If you are looking for a square-locked construction with greater flexibility, please visit our Square-Locked Flexible Conduit (Ultra Flex) page.

PVC-Coated Flexible Metal Conduit – Square Lock

PVC-Coated Flexible Metal Conduit – Square Lock Velkor PVC-coated flexible metal conduit combines a square-lock metallic core with an external PVC covering for flexible cable routing and added surface protection. Its covered construction provides a practical option where a flexible metal raceway with a smoother outer surface is preferred.

Liquid-Tight Straight Connector – Zinc Die Cast

Liquid-Tight Straight Connector – Zinc Die Cast Velkor liquid-tight straight connectors terminate flexible conduit at a box cabinet or enclosure in a direct-line arrangement. The zinc die-cast body provides a compact fitting profile while the straight entry supports orderly routing where no direction change is needed.

Liquid-Tight 90° Connector – Zinc Die Cast

Liquid-Tight 90° Connector – Zinc Die Cast Velkor liquid-tight 90° connectors provide a right-angle transition from flexible conduit into a box, cabinet, or enclosure. The zinc die-cast body helps manage routing where straight entry is restricted and a compact change of direction is required.

BX/FMC Straight Squeeze Connector – Zinc Die Cast

BX/FMC Straight Squeeze Connector – Zinc Die Cast Velkor BX/FMC straight squeeze connectors join flexible metal conduit to an enclosure through a direct entry. The squeeze-style connection secures the conduit while the zinc die-cast body provides a compact fitting for straightforward routing layouts.

BX/FMC 90° Squeeze Connector – Zinc Die Cast

BX/FMC 90° Squeeze Connector – Zinc Die Cast Velkor BX/FMC 90° squeeze connectors provide a right-angle entry from flexible metal conduit into a box or enclosure. The squeeze connection supports secure conduit engagement while the zinc die-cast elbow helps organize installations with limited straight-line clearance.
