Custom Strut Fittings manufactured from drawings, samples or controlled application requirements for repeat industrial supply.
Strut fittings connect channel sections and accessories into adjustable framing systems. The correct fitting depends on channel series, slot pattern, fastener size, joint geometry, load path and corrosion exposure.
Provide channel profile, slot geometry, mating nut, load directions, clearances and installation sequence. Custom hole patterns, offsets or weldments can change lip bearing and eccentricity. Define ASTM A1011/A36 carbon steel, ASTM A653 coated sheet or ASTM A240 stainless by grade and condition; state post-fabrication coating separately.
MFMA-4 terminology helps describe framing components, but a custom design needs calculation or testing for the exact geometry. Control datums under ASME Y14.5 or ISO 1101, general welded tolerances under ISO 13920 where invoked, and first-article inspection before production.
Trial-fit without grinding channel lips or enlarging holes. Can standard catalog ratings apply? No unless the system owner documents equivalence. Can material change to stainless? Only after checking strength, friction, galling and galvanic effects. Mark revision so custom and standard parts cannot be mixed.
Research sources: MFMA-4; ASME Y14.5; ISO 1101 and ISO 13920; ASTM A1011/A1011M, A36/A36M, A653/A653M and A240/A240M. Final validation per quotation.
Most parts in this range are made or adapted for a drawing, sample, mating interface and order program. The image on this page represents the product family; final geometry, material, finish, inspection and marking are confirmed in the quotation.
Custom Strut Fittings belongs to the strut framing connection category. Material names, standards and coating descriptions below help buyers structure an RFQ; they are not a declaration that every offered configuration complies. Grade, edition, inspection level and acceptance criteria belong on the controlled drawing or purchase specification. (industry reference data, final values per drawing/quotation)
Formed carbon steel, stainless steel, cast components and heat-treated fasteners are common. Sheet or bar grade, thickness, forming route, hole geometry and coating must match the approved drawing and complete channel system.
Use the tensile strength, yield or proof strength, elongation, hardness, impact and heat-treatment requirements published for the selected material grade. Relevant properties differ by product form and test-piece basis. They describe material quality, not the capacity of the finished Custom Strut Fittings; final suitability depends on geometry, interfaces, manufacturing condition and verification.
Specify plain, zinc-coated, hot-dip galvanized, painted, passivated or another compatible finish by a recognized coating specification where applicable. Define preparation, appearance, restricted substances, repair rules, packaging and required inspection documents instead of relying on a color photograph.

Specification caution: naming a material, coating or dimensional standard does not create a product rating, approval, certification or warranty. Any required capacity, pressure class, temperature limit, listing or test must be confirmed for the exact quoted part. (industry reference data, final values per drawing/quotation)
Selection for Custom Strut Fittings should begin with channel profile, slot and nut compatibility, connection geometry, applied-force direction, fastener system, finish and site environment. Keep required facts separate from supplier proposals so reviewers can see what is mandatory and what remains open. (industry reference data, final values per drawing/quotation)
| Decision | Information to provide | Why it matters |
|---|---|---|
| Interface and geometry | Drawing, nominal or actual dimensions, tolerances, mating components, clearances, orientation and accessible assembly space. | Prevents selection from a family name or image and allows the complete connection to be checked. |
| Service condition | Function, direction of forces, movement, vibration, indoor or outdoor exposure, moisture, chemicals and maintenance access. | Guides material, finish, locking, restraint and inspection choices without inventing an unverified rating. |
| Compliance route | Destination market, governing code, required standard edition, customer specification, marking and third-party approval needs. | Separates a generally suitable design from a configuration qualified for a regulated project. |
| Supply and quality | Quantity, release pattern, drawing revision, critical characteristics, sampling, traceability, packaging and documents. | Aligns manufacturing and inspection with the commercial requirement and repeat-order control. |
Ask the supplier to identify exclusions and assumptions in the quotation. Compare offers against the same revision and requirement list; a lower price is not comparable if material, coating, inspection, packaging or documentation scope differs. Final commercial values remain per quotation.
(industry reference data, final values per drawing/quotation)
Match labels, part identity, material or heat references where required, quantity and documents to the purchase order. Quarantine mixed, damaged, corroded or unidentifiable pieces instead of releasing them to installation.
Verify the actual mating dimensions, thread or connection form, contact surfaces, orientation and working clearance. Clean protective debris without removing functional coatings or altering critical edges.
Confirm channel and nut compatibility, place the fitting flat against the channel, engage the spring nut correctly, use the specified washers and fastener class, and tighten according to the approved system instruction. Recheck alignment and locking after the full assembly is positioned. Any torque, clearance, sealant, gasket, lubrication or locking value must come from the approved instruction for the exact product.
Record completion where the quality plan requires it. Inspect for seating, alignment, locking, leakage where relevant, coating damage and interference. Establish service checks from the system risk assessment and replace parts that fail the applicable acceptance criteria.
Compare angle, flat, wing, U-shaped and post-base fittings by connection plane and force path. Nuts and fasteners should be treated as system components, not interchangeable commodity pieces. Compatibility includes the mating dimensions, material couple, coating, fastener or seal system, installation method, inspection basis and service environment. (industry reference data, final values per drawing/quotation)
Best when an established size, connection and documented product scope match the application. Confirm the exact designation and do not extend published information to another variant.
Useful when the required function or interface differs. Review the whole assembly, because an alternative component can move forces, change clearances or require different accessories and installation controls.
Consider when geometry, material, marking, finish or packaging cannot be met by a standard item. Freeze the drawing, validation plan and change-control route before repeat production.
(industry reference data, final values per drawing/quotation)
No. The reference helps define material, dimensions, coating, test method or use practice within its own scope. Compliance requires the applicable edition, product configuration, acceptance criteria and agreed evidence. A standards list on a general webpage is not a certificate.
Name the material standard, grade, product form, heat-treatment condition where relevant, required inspection document and any supplementary tests. Use the values in the governing published standard rather than copying an isolated number. Finished-product capacity or performance still requires design and verification for the exact geometry.
Provide a legible drawing or complete dimensional description, application and mating parts, material and finish, quantity and release schedule, destination market, required standards, critical characteristics, marking, packaging and document needs. Identify any requirement that cannot change.
Only after technical and commercial review. A substitute can change strength, ductility, corrosion behavior, friction, thread fit, coating thickness, galvanic compatibility, manufacturing route and inspection evidence. Record an approved deviation before production.
Request verified data for the exact part number, revision, material, assembly orientation and mating components. The quotation or approved technical package should state the applicable basis. This page intentionally supplies no invented load, pressure, temperature or price values.
Check identity, quantity, revision, obvious damage, corrosion protection, critical dimensions and the documents named in the purchase order. Sampling, gauges and acceptance limits should be agreed in the quality plan. Keep nonconforming items segregated pending disposition.
A custom route is appropriate when the standard interface, geometry, material, finish, marking, inspection or packaging cannot satisfy the application. Provide annual demand and validation expectations so tooling, casting, forging, stamping, machining or fabrication options can be reviewed.
Reference the approved drawing revision and agreed specification, preserve approved samples or inspection records as appropriate, and require notification before material, process, tooling or supplier changes that affect critical characteristics. Reconfirm requirements after a design or application change.
