AISI 304 Stainless Steel Top Door Patch Fitting for Glass Doors

A AISI 304 Stainless Steel Top Door Patch Fitting for Glass Doors is designed for installation at the upper edge of a frameless tempered glass door, where it works together with a top pivot or transom pivot to create the upper pivot point of the door system.

Its main function is to provide accurate upper positioning and stable pivot support while allowing the glass door to swing smoothly within a compatible double-action door system.

Manufactured from AISI 304 stainless steel using a solid precision casting process, this top patch fitting is suitable for commercial frameless glass door installations in offices, hotels, apartments, reception areas and other architectural interiors.

It is suitable for both left-hand and right-hand door configurations and is commonly used with 10mm tempered glass, with suitable configurations available for 10–12mm glass.

Top Pivot Connection for Frameless Glass Doors

Unlike a bottom patch fitting that connects the lower part of the door to the floor pivot system, this top door patch fitting is installed at the upper edge of the glass panel.

It works with a compatible top pivot or transom pivot to form the upper rotating point of the door.

This upper connection helps:

• Maintain door alignment
• Stabilize the upper section of the glass door
• Provide an accurate pivot point
• Support smooth double-action movement
• Keep the frameless door system visually clean

This makes the fitting particularly suitable for architectural glass entrances where exposed conventional hinges are not desired.

Solid Precision-Cast AISI 304 Construction

The fitting body is manufactured from AISI 304 stainless steel using a solid precision casting process.

Compared with lightweight fabricated components, a solid cast structure provides a robust body for the pivot connection and helps maintain dimensional stability during repeated door movement.

AISI 304 stainless steel also provides good corrosion resistance and durability for typical indoor commercial applications.

Compatible with Top Pivot and Transom Pivot Systems

Depending on the complete door configuration, the top patch fitting can be matched with:

Top Pivot
Used when the upper pivot is fixed directly to an overhead structural surface or compatible frame component.

Transom Pivot
Used where the frameless glass door is installed beneath a glass transom or compatible overhead patch fitting system.

The pivot specification should be confirmed together with the glass cut-out and door dimensions before glass processing.

Double-Action Door Compatibility

This top patch fitting is suitable for compatible double-action glass door systems.

When combined with the correct top pivot and lower door hardware, the door can swing in both directions.

The fitting is also suitable for both:

Left-hand doors
és
Right-hand doors

This non-handed design helps simplify product selection for glass fabricators, distributors and project contractors.

Glass Requirements

This model is designed for tempered glass.

The common glass thickness is:

10mm

Suitable configurations can also support:

10–12mm tempered glass

Because the fitting requires accurately processed glass openings or cut-outs, the final fitting dimensions should be confirmed before the glass is drilled, cut or tempered.

Important Note

These fittings are not intended for use with laminated glass.

The glass specification should therefore be confirmed before production and installation.

Recommended Door Size Guidelines

For this hardware configuration, the following values can be used as reference limits:

Door Requirement	Recommended Limit
Maximum Height	102 in / 2591mm
Maximum Width	42 in / 1092mm
Maximum Weight	194 lbs / 88kg
Common Glass Thickness	10mm Tempered Glass

The actual allowable door size should also be checked against the complete pivot and floor hardware system.

For project applications, door weight, glass dimensions, pivot model and installation conditions should be confirmed together rather than evaluating the top patch fitting independently.

Surface Finish Options

The fitting is available in three standard finishes:

Mirror Polished
Suitable for polished stainless steel architectural hardware and bright-finish glass door systems.

Szatén
Provides a softer brushed stainless steel appearance widely used in offices, hotels and commercial interiors.

Black
Suitable for contemporary frameless glass door systems and modern black architectural hardware schemes.

For a complete glass door installation, the finish of the top patch fitting should ideally match the bottom patch, floor spring cover, handles and other visible fittings.
