An EMT conduit two hole strap is a metal fastening component used to secure electrical metallic tubing to a wall, ceiling, panel, or other supporting surface. It normally has two fixing holes and a curved body shaped to hold one conduit run in position. When I help B2B buyers select this product, I focus on four points first: conduit trade size, strap material, hole and screw compatibility, and the installation environment. For bulk orders, I also recommend confirming drawings, surface treatment, packaging, minimum order quantity, and production lead time before placing a purchase order.

I prepared this guide for electrical wholesalers, conduit distributors, contractors, panel builders, project purchasing teams, and importers sourcing EMT conduit fittings in volume. It is also useful for buyers who need a dependable alternative to a one-hole strap when improved alignment or two-point fastening is preferred. The guide explains the selection process without assuming that one material or size fits every project. Because local electrical codes and project specifications can differ, the final product should always be checked against the applicable requirements.
An EMT conduit two hole strap is a support fitting designed to hold electrical metallic tubing against a mounting surface. The two holes allow the installer to use two fasteners, which can help keep the conduit aligned and reduce rotation during installation. The strap is not normally used to join two conduit sections; its primary purpose is support and positioning.
For example, a strap intended for 1/2-inch EMT should not be assumed to fit 3/4-inch EMT, even when the overall product shape looks similar. The internal width and curvature must match the outside diameter and installation requirement of the conduit. I therefore treat the marked trade size and dimensional drawing as essential purchasing information, rather than relying only on product photographs.
EMT conduit is commonly identified by trade sizes such as 1/2 inch, 3/4 inch, and 1 inch, with larger sizes used in appropriate installation systems. A two hole strap should be ordered according to the conduit size specified by the project, not simply by measuring a visually similar existing strap. The exact outside diameter, strap width, hole diameter, center spacing, and overall height should be confirmed on the supplier drawing.
| Selection Item | What to Confirm | Why It Matters |
|---|---|---|
| Trade size | For example, 1/2 inch, 3/4 inch, or 1 inch EMT | Determines whether the conduit sits correctly in the strap |
| Material | Steel, stainless steel, aluminum, or another specified alloy | Affects weight, corrosion behavior, strength, and cost |
| Hole pattern | Hole diameter, center distance, and slot or round-hole design | Must work with the selected screw, anchor, and mounting surface |
| Finish | Plain, plated, painted, anodized, or other requested treatment | Influences surface protection and appearance |
Steel is often selected when buyers need a rigid, economical strap for general construction and electrical distribution. Depending on the required specification, the product may use a protective plated or coated surface rather than a plain finish. I recommend confirming the base material, coating type, coating thickness if specified, and visual acceptance standard before approving mass production.
Stainless steel can be considered for areas where corrosion resistance is a major purchasing factor, although the correct grade must be specified rather than assumed. It may be suitable for damp, exposed, or chemically demanding environments when the project design calls for it. Stainless steel can increase material cost, so I suggest using it where environmental exposure and service requirements justify the additional expense.
Aluminum is a useful option when low weight, compatibility with aluminum conduit systems, or a non-ferrous material is important. As an aluminum pipes and fittings supplier, I can help buyers compare an aluminum strap specification with the conduit and surrounding hardware. However, aluminum does not automatically provide the same mechanical or surface behavior as steel, so the buyer should review load expectations, fastener compatibility, and the installation environment.
I recommend matching the strap to the complete installation rather than choosing only by nominal size. First, identify the conduit material and trade size, then review the mounting surface, expected exposure, fastening method, and project quantity. Finally, confirm that the proposed finish and material are suitable for contact with nearby components and the intended service environment.
For ordinary indoor work, buyers may prioritize dimensional consistency, efficient installation, clean appearance, and competitive unit cost. Steel or aluminum may both be considered, depending on the conduit system and project specification. The two-hole design is particularly useful when the installation plan requires stable positioning along walls, ceilings, equipment frames, or distribution areas.
For damp, outdoor, or industrial locations, surface protection deserves more attention than appearance alone. I suggest asking for the recommended material and finish for the exposure category, together with available inspection criteria. The buyer should also consider whether the selected fasteners and anchors provide compatible corrosion performance, because the strap cannot compensate for unsuitable installation hardware.

When the project uses aluminum conduit or aluminum pipe products, material compatibility should be reviewed as part of the specification. Contact between dissimilar metals can require additional consideration depending on moisture, contaminants, and the installation design. I recommend that buyers provide the full material combination to the supplier so the proposed strap and finish can be evaluated in context.
Start with the conduit trade size and request a dimensioned drawing for approval. Important details include the inside curve, material thickness, strap width, hole diameter, hole center distance, and total height. If the strap is intended for a specific screw or anchor, include that information in the inquiry so the hole design can be reviewed.
Specify whether the project requires steel, stainless steel, aluminum, or another material. For coated or plated products, identify the requested finish and any appearance or corrosion-resistance criteria that can be verified during inspection. If the buyer has no fixed finish, I recommend comparing the environment, expected service period, cost target, and compatibility requirements before making a decision.
For a bulk order, quality control should cover more than the raw material. I suggest confirming dimensional inspection, hole alignment, burr control, surface appearance, quantity per carton, carton labeling, and pallet requirements. A consistent package count can simplify warehouse receiving and reduce counting errors during distribution.
Unit price is only one part of the total sourcing decision. Ask for the minimum order quantity, tooling or sample charges if applicable, production lead time, packing method, payment terms, and shipping basis in the same quotation. A lower unit price may be less useful if the MOQ exceeds your inventory plan or if the delivery schedule does not support the project.
| Commercial Question | Recommended Buyer Action |
|---|---|
| What is the MOQ? | Compare the supplier quantity with forecast demand and storage capacity |
| How long is production? | Request a written estimate after size, material, finish, and packaging are confirmed |
| Can the supplier provide samples? | Use samples to check fit, holes, finish, and packaging before mass production |
| Is customization available? | Confirm drawings, private labeling, carton marks, and production approval procedures |
One common mistake is ordering by a product name without confirming the actual trade size and drawing. Another is selecting a finish based only on color, without understanding the underlying material or surface treatment. Buyers also sometimes compare quotations that use different packaging quantities, making the apparent unit price difficult to evaluate accurately.
Another risk is failing to approve a sample before a large shipment. A sample provides an opportunity to check conduit fit, hole spacing, burrs, surface quality, and carton presentation before the order becomes difficult to change. I also recommend recording the approved drawing and inspection requirements as part of the purchase documentation.
At SIOSAN, I support buyers by organizing EMT conduit two hole strap inquiries around measurable specifications. Our communication can cover size selection, aluminum and other material options, surface finish, drawing confirmation, packaging, and export-order coordination. When a buyer provides the conduit size, application environment, target quantity, and preferred delivery schedule, I can prepare a more relevant product discussion.
For repeat distribution orders, I recommend establishing an approved specification that includes the product drawing, material, finish, hole pattern, carton quantity, and labeling details. This helps reduce ambiguity between purchase orders and future replenishment. Where customization is required, the final feasibility, MOQ, price, and lead time should be confirmed after the technical information is reviewed.
The right EMT conduit two hole strap is the one that matches the conduit size, material system, mounting method, environmental conditions, and purchasing requirements of the project. I recommend starting with a dimensioned specification, then comparing material and finish options before evaluating price and lead time. This process helps prevent fit problems and creates a clearer basis for bulk sourcing.
To begin an inquiry with SIOSAN, prepare the required EMT trade sizes, estimated quantity, preferred material, surface finish, packaging expectations, destination market, and delivery target. I can then help review the specification and identify the information needed for quotation and sample approval. A clear technical brief at the beginning usually makes the final purchasing decision faster and more reliable.
