When sourcing EMT two hole straps in bulk, confirm the conduit trade size, strap dimensions, material, finish, mounting-hole layout, and required documentation before comparing quotations. A two-hole strap has two mounting holes that secure EMT conduit to a supporting surface, but product dimensions and finishes can vary by supplier and project specification. At SIOSAN, we recommend sharing a drawing or complete specification with your inquiry so we can assess the requested product and quote against the same requirements.

This guide is intended for electrical wholesalers, importers, distributors, contractors, and OEM buyers evaluating EMT two hole strap factories in China. It is also useful for purchasing teams that need to standardize a product across multiple job sites or combine conduit accessories with a broader pipe and fittings order. The guidance focuses on specification and sourcing decisions, not on replacing project drawings, installation instructions, or local electrical-code requirements.
An EMT two hole strap is a formed metal support used to hold electrical metallic tubing against a wall, ceiling, or other suitable surface. Its two mounting holes allow the installer to fasten the strap at two points, while the curved section supports the conduit. The required strap shape and dimensions depend on the conduit size, mounting surface, installation design, and fastening method.
Buyers commonly specify these straps for conduit runs in commercial, industrial, and infrastructure projects. They may be used in exposed installations where conduit needs to be supported along a structural surface, subject to project requirements and applicable codes. The strap is one part of a complete installation: the conduit, anchors or screws, support spacing, and substrate all affect the finished assembly.
For example, an inquiry might identify EMT with a trade size of 1/2 inch, 3/4 inch, or 1 inch. These are examples of trade-size descriptions, not the strap’s measured width or outside diameter. Provide the applicable conduit standard or a sample if the order will serve more than one market.
Two-hole straps are offered in different material and finish combinations, depending on the product range and intended environment. Common options buyers may ask suppliers about include carbon steel with a protective coating, stainless steel, and aluminum. Availability, forming characteristics, corrosion resistance, and cost differ, so confirm the exact material and finish rather than relying on a general description such as “metal strap.”
For indoor, dry locations, buyers may evaluate a coated steel option if it meets the project specification. For outdoor, damp, or corrosive environments, request details about the coating or alloy and confirm whether it is suitable for the intended exposure. Do not treat a finish name alone as proof of performance; request relevant product documentation or test evidence when the project requires it.
Thickness is another specification to define. If your design calls for a particular thickness, state it in millimeters, such as 1.0 mm as an example of a buyer-provided requirement—not as a universal EMT strap specification. The supplier should confirm the proposed material thickness and any tolerances before production.
A clear request for quotation helps suppliers assess the same product and reduces avoidable revisions. Provide a drawing where possible, with dimensions in millimeters and the required units clearly stated. If you do not have a drawing, include the details below and ask the factory to confirm its proposed dimensions for approval.
| Specification | What to Confirm |
|---|---|
| Conduit compatibility | EMT trade size and the applicable regional or project standard |
| Overall dimensions | Strap width, formed profile, and relevant inside dimensions |
| Material | Material type and grade where required by the design |
| Thickness | Specified thickness in millimeters and acceptable tolerance |
| Mounting holes | Hole diameter, shape, and center-to-center spacing |
| Surface finish | Coating or finish type, color if relevant, and documentation needs |
| Order requirements | Quantity, packaging, labeling, destination, and requested delivery window |
The product’s two mounting holes are a defining feature, but their diameter and spacing are not universal. For example, specify a hole center spacing in millimeters from your drawing instead of assuming that a factory’s standard pattern matches your installation. If the strap must fit an existing assembly, send a sample or dimensioned drawing for review.
SIOSAN supply professional and honest service.
Start with the conduit trade size and the intended installation environment. Identify whether the project is indoors or outdoors, whether exposure to moisture or corrosive conditions is expected, and what surface the strap will attach to. These details help narrow material and finish choices, but final suitability should follow the project design and local requirements.
Specify the strap profile and the dimensions needed to seat the conduit without forcing it into the strap. Confirm the hole diameter and spacing against the selected fastener and mounting surface. If the fastener or anchor is not supplied with the strap, state that clearly so both parties understand the product scope.
Review the supplier’s drawing, quotation, sample, or other agreed approval document before authorizing a bulk order. Check that the material, thickness, finish, hole pattern, and packaging match the RFQ. Keep the approved version with the purchase order so later batches can be checked against the same requirements.
Bulk pricing depends on the specified material, thickness, finish, order quantity, packaging, and any tooling or customization needed. A lower unit price may not represent better value if it excludes a required finish, uses a different dimension, or involves packaging that is unsuitable for your warehouse. Ask suppliers to itemize the product specification and commercial terms so offers can be compared consistently.
Minimum order quantities and production lead times vary by factory, product configuration, and current production schedule. Request the MOQ and estimated lead time for the exact item, and ask whether a sample order or mixed-size order is possible. Treat delivery estimates as subject to order confirmation, production approval, and shipping arrangements rather than assuming a fixed turnaround.
When evaluating a factory, focus on its ability to communicate technical details and maintain an agreed specification. Request evidence relevant to your product and market rather than relying on broad claims about quality or compliance. If a supplier cannot answer a dimension or material question, resolve it before purchase rather than leaving the detail open to interpretation.
One frequent mistake is ordering by product name alone, without defining the conduit size or strap dimensions. Another is assuming that a finish described as galvanized or coated will meet a particular corrosion requirement without confirming its specification. Buyers can also overlook mounting-hole spacing, packaging, and destination-market documentation until after a quotation has been accepted.
Reduce these risks by using one RFQ template for every supplier and recording any deviations in writing. If substitutions are acceptable, define them in advance; otherwise, state that the quoted item must match the approved specification. For repeat orders, refer to the previous approved drawing and request confirmation that the material and finish remain unchanged.
SIOSAN works with B2B buyers sourcing EMT conduit fittings and related products, including aluminum pipe requirements. For an EMT two hole strap inquiry, send the conduit trade size, drawing or sample, material and finish preference, order quantity, destination, and any documentation requirements. We can review the requested details, clarify open specification points, and discuss available sourcing options before you proceed.
The right EMT two hole strap is the one that matches your conduit, mounting layout, environment, and project specification—not simply the lowest-priced item described by a general product name. Before placing a bulk order, define dimensions, material, thickness, finish, hole pattern, packaging, and required documentation, then approve the supplier’s confirmation. To begin, send SIOSAN your drawing or complete specification and target order quantity so we can discuss a suitable quotation and next steps.
