JC-A14 Stainless Steel Shower Door Pivot Hinge | Heavy Duty Top & Bottom Mount | Brushed/Black Finish
JC-A14 Stainless Steel Shower Door Pivot Hinge | Heavy Duty Top & Bottom Mount | Brushed/Black Finish
Explore the JC-A14 Heavy Duty Shower Door Pivot. Precision engineered from 201/304 Stainless Steel for 8-12mm glass. Features a robust rotating shaft design, available in Brushed, Mirror, and Black finishes. Perfect for modern frameless showers.
Product Overview: The Architect’s Choice for Frameless Showers
In the realm of contemporary bathroom architecture, transparency and minimalism are paramount. The JC-A14 Shower Door Pivot is engineered to deliver exactly that. Unlike traditional side-mounted Shower Hinges that interrupt the clean lines of glass, the JC-A14 operates as a top-and-bottom rotating shaft system. This design creates a sleek, floating glass appearance that is highly sought after in luxury hotels and modern residential projects.
The JC-A14 is not just visually appealing; it is a powerhouse of functionality. By transferring the weight of the heavy glass door directly to the floor (or shower curb), it alleviates stress on the wall, making it the safest and most durable solution for heavy, frameless glass doors ranging from 8mm to 12mm in thickness.
Technical Specifications
Based on the provided technical diagram and image, here are the precise specifications for the JC-A14:

1. Superior Weight Distribution
One of the primary advantages of the JC-A14 pivot system over traditional wall-mount hinges is physics. Standard hinges carry the weight of the door through shear force on the wall anchors. Over time, heavy glass can cause these anchors to loosen, leading to door sagging.
The JC-A14 pivot hinge transfers the vertical load directly downwards into the floor structure. This makes it an incredibly stable solution, particularly for wider doors or installations where the side walls are not reinforced with blocking.
2. Material Excellence: The 304 Stainless Steel Advantage
Bathrooms are hostile environments for metals due to constant humidity and exposure to cleaning chemicals.
Corrosion Resistance: We utilize premium 304 Stainless Steel for the JC-A14. This alloy contains high levels of Chromium and Nickel, ensuring the hinge remains rust-free and structurally sound for years.
The JC-A14 is designed with the installer in mind.
Adjustable Mounting: The technical drawing highlights oval-shaped slots on the mounting plate. These slots allow for lateral adjustment during installation. If your drill holes are slightly off, or if the walls are not perfectly plumb, these slots allow you to shift the pivot point to align the door perfectly before tightening the screws.
The image showcases the Wire Drawing (Brushed) finish. This finish is achieved by abrading the metal with a fine grit belt, creating a unidirectional grain. This texture is not only beautiful but practical; it does not show water spots as easily as polished chrome and is highly resistant to surface scratching. It pairs seamlessly with our range of brushed Shower Door Handles and towel bars.
Installation Guide & System Integration
Step-by-Step Installation Overview
Marking: Use a plumb bob or laser level to align the top pivot point directly over the bottom pivot point. Misalignment is the #1 cause of pivot failure.
Drilling: Secure the bottom pivot plate to the floor/curb and the top plate to the header.
Glass Prep: Ensure the glass has the correct cutouts and holes (40mm spacing) per our template.
Assembly: Loosen the hex screws on the JC-A14 body. Insert the supplied gaskets into the clamp.
Mounting: Slide the glass into the pivot clamp. The gaskets protect the glass from metal contact. Tighten the hex screws evenly.
To build a fully functional frameless shower enclosure, the JC-A14 pivot should be integrated with compatible hardware:
Fixed Panels: If your shower design includes stationary glass panels adjacent to the door, use our Glass Clamps / Spiders to secure them. We match the finish of the clamps to the JC-A14 for a cohesive look.
Sealing: Since pivot doors have a clearance gap at the top and bottom (13mm neck height shown in drawing), we recommend installing translucent vinyl seals to ensure water retention.
To maintain the pristine condition of your JC-A14 pivot hinges:
Cleaning: Clean regularly with mild soap and warm water using a microfiber cloth.
Avoid Abrasives: Do not use steel wool or harsh chemicals like bleach, as these can pit the stainless steel surface.
Q: Can the JC-A14 pivot swing 360 degrees?
A: Technically, the pivot mechanism allows for full rotation. However, in a shower application, the rotation is usually limited by the wall, the threshold, or vinyl seals to 90 degrees (in/out) or 180 degrees.
Q: Is this hinge handed (Left or Right)?
A: No, the JC-A14 is non-handed. It is reversible and can be installed on either the left or right side of the door opening.
Q: What is the maximum door width for this pivot?
A: We generally recommend a maximum door width of 800mm (approx. 32 inches) for 10mm glass to ensure stability and ease of use. For wider doors, please consult our engineering team for heavy-duty options.

Corrosion Resistance: We utilize premium 304 Stainless Steel for the JC-A14. This alloy contains high levels of Chromium and Nickel, ensuring the hinge remains rust-free and structurally sound for years.
Solid Construction: As seen in the product image, the main block is a solid, machined component, not a hollow shell. The 19mm thick top plate ensures rigidity, preventing any "play" or wobble in the door movement.
The JC-A14 is designed with the installer in mind.
Adjustable Mounting: The technical drawing highlights oval-shaped slots on the mounting plate. These slots allow for lateral adjustment during installation. If your drill holes are slightly off, or if the walls are not perfectly plumb, these slots allow you to shift the pivot point to align the door perfectly before tightening the screws.
Glass Preparation: The 40mm hole spacing is a standard specification, making it easy for glass fabricators to prepare the door panel without specialized custom tooling.

Support: For designs without a header, consider using our glass-to-wall stabilizer bars to anchor the fixed panels rigidly.
To maintain the pristine condition of your JC-A14 pivot hinges:
Cleaning: Clean regularly with mild soap and warm water using a microfiber cloth.
Avoid Abrasives: Do not use steel wool or harsh chemicals like bleach, as these can pit the stainless steel surface.
Lubrication: A drop of non-corrosive silicone lubricant applied to the pivot pin once a year will ensure the door continues to operate silently and effortlessly.
