EMT Two Hole Strap Factory in China: A Buyer’s Guide to Sizes, Materials, and OEM Sourcing

When sourcing EMT two-hole straps from a factory in China, start by matching the strap to the conduit trade size, installation conditions, required material and finish, and mounting-hole layout. Then ask suppliers to confirm those details against a drawing or approved sample before discussing price and production timing. At SIOSAN, we help B2B buyers clarify these requirements so a quote is based on a defined product rather than a size name alone.

This guide explains what to specify, how to compare material options, and what to check when evaluating OEM support. It is intended for electrical wholesalers, distributors, contractors, importers, and private-label buyers who need a repeatable sourcing process. Product availability, order quantities, and production schedules should be confirmed for each specification.

Key Takeaways

Confirm the EMT trade size and the strap’s actual fit before placing a production order.
Specify material, thickness, finish, hole geometry, and packaging in a drawing or written specification.
Request a quotation that separates tooling or setup costs, unit pricing, minimum order quantity, and shipping terms.
Evaluate a factory’s ability to communicate, document, sample, and control the exact version you approve.

Who This Guide Is For

This guide is for B2B buyers comparing an EMT two-hole strap factory in China for project supply, distribution, or OEM production. It is especially relevant when you are moving from a general product inquiry to a quote that must be checked by engineering, purchasing, and quality teams. If you already have a part number or drawing, use it as the basis for supplier discussions.

If you do not have a drawing, you can still begin with the intended conduit size, installation environment, preferred material, and target packaging. Ask the supplier to identify any assumptions in its proposal rather than treating an informal product description as a final specification. This reduces avoidable differences between the sample, quotation, and eventual order.

What Is an EMT Two-Hole Strap?

Basic design and function

An EMT two-hole strap is a formed fitting used to secure electrical metallic tubing to a mounting surface. Its curved section sits around the conduit, while two holes provide locations for fasteners. The strap’s fit, formed profile, and mounting layout all affect whether it suits a particular installation.

Buyers commonly use these straps in commercial, industrial, and building projects where EMT must be supported along a wall, ceiling, or other suitable surface. The correct installation method and support spacing depend on applicable project requirements and local electrical codes. A strap supplier can provide product information, but the buyer or project engineer remains responsible for confirming installation compliance.

Sizes, Materials, and Finish Options

Match the trade size to the actual fit

EMT is commonly specified by trade size, with examples including 1/2 in, 3/4 in, and 1 in. These labels are not a substitute for checking the strap’s internal profile against the conduit you plan to use. Confirm the manufacturer’s size designation, dimensional drawing, and sample fit, particularly if the product will be used with tubing from multiple sources.

For OEM orders, state whether your size list follows a particular market convention and whether each size requires a separate part number. Ask the factory to show the critical dimensions on a drawing, such as the curved section, overall width, hole spacing, and hole diameter. If you work in metric, request dimensions in mm as well as any applicable inch-based trade-size references.

Choose material and finish for the application

Material selection should reflect the installation environment, required strength, corrosion exposure, customer expectations, and applicable project specification. Straps may be offered in different metals or finishes depending on the supplier’s product range; do not assume that a particular material or coating is available without confirmation. Ask for the base material, nominal thickness, finish description, and any supporting product documentation.

For example, steel with a protective finish may be considered for general indoor use, while a more corrosion-resistant option may be appropriate where the environment or project requirements call for it. Aluminum can be considered where its material properties suit the application, but it should not be treated as a direct substitute without checking design and project requirements. The supplier should identify the exact option being quoted rather than using broad terms such as “metal strap.”

How to Build a Clear OEM Specification

Information to include in an RFQ

A useful request for quotation identifies the product and the criteria that define acceptance. Include the conduit trade size, material, thickness, finish, overall dimensions, hole details, and any marking or packaging requirements. Attach a drawing or reference sample when possible, and state which features are critical and which may be proposed by the supplier.

You will get efficient and thoughtful service from SIOSAN.

Product: EMT two-hole strap, size range, and part-number system.
Dimensions: Overall length and width, formed profile, hole diameter, and center-to-center spacing.
Material and finish: Exact material designation and finish requirement, subject to supplier confirmation.
OEM details: Logo or private-label requirements, label text, carton markings, and packaging method.
Order details: Quantity by size, delivery destination, target schedule, and requested trade terms.

Use sample dimensions only as examples, not as universal EMT strap specifications. For instance, a buyer might place a 6 mm hole diameter or 1.0 mm material thickness on a preliminary drawing, but those values must be checked against the application and approved design. Record all accepted dimensions and tolerances in the final document so the factory and buyer are working from the same revision.

Sample approval and production control

Before committing to repeat orders, agree how a sample will be reviewed and what constitutes approval. Check that it fits the intended conduit, sits flat against the mounting surface, and matches the agreed hole layout and finish. Keep the approved sample or signed drawing as a reference for later production discussions.

For ongoing OEM supply, ask how the factory identifies product revisions and handles changes to material, tooling, finish, or packaging. A simple written change-approval process can help prevent a substitution from being made without buyer review. Where inspection records or material documents are required, define them before the order is confirmed.

Pricing, MOQ, and Lead-Time Questions

Pricing depends on the agreed specification, order quantity, material, finish, packaging, and delivery terms. Request a quotation that shows the price basis and clarifies whether tooling, sampling, or packaging setup has a separate charge. Compare like-for-like offers; a lower unit price may reflect a different material, finish, or level of packaging.

Minimum order quantity and production lead time are supplier- and order-specific, so confirm both in writing for each size and finish. Ask whether mixed sizes can be combined toward an MOQ, how sample approval affects the schedule, and when the quoted production period begins. Also confirm whether the schedule refers to production time only or includes inspection and shipping.

Factory Evaluation Checklist

Questions to ask a potential supplier

Can you quote each requested EMT trade size and provide a drawing or dimensional confirmation?
Which materials and finishes can you offer for this design, and how are they identified in the quotation?
Can you produce a sample for review before a bulk order, and what information is needed to prepare it?
How do you control approved drawings, revisions, packaging details, and repeat orders?
What are the MOQ, sample or setup costs, production schedule, and shipping assumptions for this exact specification?

Look for precise answers and documents that correspond to the product being quoted. A supplier’s general capability statement is less useful than a clear drawing, a complete quotation, and agreed sample-review steps. If a response leaves a critical point open, resolve it before treating the offer as comparable to another supplier’s quote.

How SIOSAN Supports Your Sourcing Process

We can discuss size range, material and finish options, OEM identification, packaging, and the information needed for a practical RFQ. Final availability and terms depend on the product details and order requirements.

To begin, send us your size list, drawing or sample reference, preferred material and finish, estimated quantity by size, and destination market. We can then review the information, identify questions that need resolution, and prepare a quotation for the defined scope. If your specification is still under development, tell us the application and target requirements so we can clarify what needs to be confirmed before sampling.

Conclusion

The most reliable way to source EMT two-hole straps from a factory in China is to define the fit, dimensions, material, finish, and OEM requirements before comparing quotations. Trade-size labels provide a starting point, but drawings and sample approval help confirm the actual product. Buyers should also verify MOQ, pricing basis, schedule, and change-control expectations for every proposed order.

Your next step is to prepare an RFQ with the requested sizes, critical dimensions, material and finish requirements, packaging details, quantities, and destination. Share it with SIOSAN for a specification review and sourcing discussion. A clear, approved specification gives both parties a stronger basis for sampling, pricing, and repeat supply.
