Specify frameless shower door hardware as one approved assembly: glass schedule, hinge and clamp models, mounting surfaces, panel layout, finish and project documentation. A broad hardware category or a material label alone does not prove that parts fit the glass or meet the project requirements.
Key Takeaways
- Use the current glass shop drawing and match every fitting to its model-specific drawing and instructions.
- Check glass type, thickness, holes, notches, edge finish, door swing and mounting substrate as a connected set.
- Request documented limits for the exact hinge configuration; do not reuse generic load or cycle figures.
- Confirm material, finish and cleaning instructions for the actual exposure and project specification.
- Have the responsible designer or authority confirm the applicable accessibility and safety-glazing requirements.
Start with the enclosure and glass drawings
Identify each fixed panel, door panel, opening direction and connection point. The approved glass schedule should identify the selected glass product and its fabrication details. Compare the drawing with the hardware schedule before release to production. The nominal glass thickness is one compatibility check; it does not by itself establish the door dimensions or fitting capacity.
When a project calls for tempered or laminated glass, confirm the exact glass build-up with the fabricator and designer. Do not infer that two types of glass can share a hinge or clamp because their outside dimensions are similar. See the glass compatibility checklist for the drawing details to match.
Select hinges by configuration, not by name alone
Wall-to-glass hinges, glass-to-glass hinges and pivot fittings connect different parts of an enclosure. Check the model drawing for the intended panel relationship, glass preparation, opening path, mounting surface, fixing method and adjustment range. Confirm that the selected hardware is documented for the actual panel arrangement, including the specified number and position of fittings.
For clamps, brackets, handles and seals, verify the hole pattern, glass interface, gasket, clearance and finish against the same revision of the glass and hardware documents. Avoid mixing parts from different product families unless the supplier confirms the combination in writing.
Compare material and finish documentation
Ask for the material and finish description for each part rather than relying on broad labels such as stainless, brass, marine grade or premium. Record the base material, coating or plating system, color, care instructions and any project-specific acceptance criteria. If a coating or corrosion claim matters to the project, request the test report, specimen details, acceptance criteria and the exact product configuration covered by that report.
A salt-spray duration is not a service-life prediction. ASTM B117 describes a controlled salt-fog test practice, and ASTM notes that results should be interpreted within the limits of the method. Compare reports only when the tested products, preparation and evaluation criteria are relevant to the finish being purchased. Read our guide to reading salt-spray reports before comparing supplier claims.
Ask for model-specific limits and installation instructions
Where a supplier publishes a door-size, weight, cycle or adjustment limit, request the document that identifies the applicable model and tested or approved configuration. Check the units, glass dimensions, fitting count, mounting substrate and installation conditions behind the figure. Do not copy a number from a different hinge or assume a rating applies to a complete enclosure.
Installation instructions should identify the approved fixings, substrate, drilling process, alignment checks and care requirements. Fully tempered glass must be fabricated before heat treatment; the National Glass Association explains that heat-treated glass should not be cut, drilled or edged afterward. See the NGA glazing manual.
Check project code and accessibility requirements
Safety-glazing, accessibility and building requirements depend on the project location and application. In the United States, shower doors and enclosures are included in the federal architectural-glazing standard; other jurisdictions may use different rules. Ask the project designer or authority having jurisdiction to identify the required standard and acceptance evidence. A hardware product listing by itself does not establish that the completed opening complies.
Do not label a product or enclosure ADA-compliant based only on a hinge feature. Confirm the dimensions and operation of the complete opening against the current project requirements. For procurement planning, see our shower-hardware materials guide and professional installation guide.
Use a release checklist for every order
- Approved glass schedule and shop drawing.
- Exact hinge, clamp, fitting and finish model numbers.
- Drawings showing hole and cut-out locations, edge details and tolerances.
- Written confirmation that the documented limits cover the selected configuration.
- Installation, cleaning and maintenance instructions.
- Required safety, code, accessibility or test documentation for the project location.
Keep the approved revision with the purchase order and sample approval. If glass, hardware or finish changes, review the assembly again before manufacture.
Frequently Asked Questions
What information is needed to specify frameless shower hardware?
Provide the glass schedule and shop drawing, panel layout, door swing, mounting surfaces, hardware models, finish and the project location so the applicable requirements can be confirmed.
Can I choose a hinge based only on its advertised weight rating?
No. Check that the document applies to the exact model, glass configuration, fitting count, door dimensions and mounting conditions in the approved design.
Does a salt-spray test prove how long a finish will last?
No. A test duration does not directly predict service life. Review the test method, specimen, evaluation criteria and product configuration covered by the report.
Does an ADA-compliant hinge make the whole shower opening compliant?
No. Confirm the complete opening and installation against the project requirements with the responsible designer or authority.
