Quick answer — 90 vs 135 degree shower hinges: Select 90° or 135° shower hinges from the required relationship between the fixed and moving glass, then match glass thickness, gasket set and cut-out. The angle label is not a universal opening-range or interchangeability statement. For distributor orders, keep geometry, thickness and finish as separate stock attributes.
For distributors building a shower hardware assortment, this decision tree turns a broad hinge category into distinct, supportable stock items. The aim is to help sales staff ask the right questions before accepting an installer’s order.
Branch 1: what does the enclosure drawing show?
Elim catalogue comparison: Elim’s linked 90° finish-concept hinge and 135° hinge identify different enclosure geometries. Their catalogue names support angle-based selection; neither name supplies a universal glass-processing template. Catalogue references: 90° glass-to-glass hinge, 135° glass-to-glass hinge.
Buying decision: Resolve the plan angle before preparing glass. If a replacement enquiry provides only a hinge photograph, obtain the panel relationship and existing cut-out as well. Buying an angle-labelled substitute without those two checks can leave usable glass incompatible with the delivered hardware.
CRL’s shower-hardware catalogue illustrates how hinge families and accessories are organized. It is an external product reference, not proof that similarly named models share cut-outs or operating characteristics.

Branch 2: have angle and swing been separated?
Compare the connection angle with the model’s operating information. The CRL Vienna 092 example and Vienna 045 example illustrate separate product specifications for nominally different glass-to-glass arrangements. Read their model information as CRL-specific data.
For the Elim item being ordered, obtain the relevant drawing and instructions. Confirm the supported glass configuration, door dimensions and any stated limitations for that exact model. Do not transfer a competitor’s capacity, tightening value or glass cut-out to an Elim hinge.
| Sales question | Document needed |
|---|---|
| Which panel angle? | Enclosure plan |
| Which door movement? | Model operating information |
| Which glass preparation? | Approved model template |
| Which supplied parts? | Assembly parts list |
Which gasket changes between 10 mm and 12 mm shower glass?
CRL’s V1E092 90° hinge drawing identifies thick gaskets on each side for 10 mm glass and thin gaskets on each side for 12 mm glass. This is a model-specific example; it is not a gasket instruction for Elim hinges.
| Selection item | Keep it distinct |
|---|---|
| 90° or 135° | Required panel-to-panel geometry |
| 10 mm or 12 mm | Glass thickness and matching gasket set |
| Hinge cut-out | Exact model drawing, not the angle label |
A change from 90° to 135° is not solved by changing gaskets. Conversely, keeping the same angle does not make a gasket suitable for every thickness. For distributor stock, separate angle, glass range and finish in the SKU description so replacement orders do not rely on photographs.

Branch 3: is the glass already processed?
The AGWA glass-standard notice gives Australian specification context. The CPSC tempered-glass safety alert provides separate safety background. Neither authorizes adapting processed glass to fit an incompatible hinge.

Branch 4: what should the distributor stock?
Use the shower-hinge quality guide to define the information sales and inspection teams need. For a private-label version, coordinate changes through Elim’s OEM process rather than assuming a new finish or mark leaves every approval unchanged.
An illustrative launch assortment might contain one approved 90° model and one approved 135° model in the same confirmed finish. Order quantities should follow the distributor’s actual demand and commercial agreement; this example does not predict sales or recommend a universal stock ratio.
Branch 5: can the stock be delivered and supported?

Where stainless components are specified, ASSDA’s cleaning guidance provides maintenance background; do not apply it indiscriminately to every coating or base material. Ask for care information suited to the actual supplied finish.
Use ISTA’s procedure overview to discuss protective packing and Trade.gov’s document guide to coordinate shipment records. Keep angle variants distinguishable after individual packs are removed from the master carton.
Counter questions answered
Does 135° mean the door swings through 135°? Not necessarily. Check the connection geometry and permitted movement as separate model specifications.
Can every hinge in one angle category use the same cut-out? No. Approve the template for the exact model and revision.
What should a distributor send for a quotation? Share the enclosure types, model preferences, glass details, finish references and quantities through the shower hardware enquiry form. Request clear variant descriptions that can be reused in purchasing, packing and sales support.
