Brazil Style Bottom Insert for Floor Spring Systems

The key function of this bottom door patch fitting is to create the connection between the lower section of a frameless glass door and the floor spring system.

Acest Brazil Style Bottom Insert structure is designed to work as part of a pivoting glass door assembly.

Once installed, the floor spring controls the opening and closing movement of the door, while the bottom patch fitting transfers the door load and provides the lower pivot connection.

This makes the fitting suitable for frameless glass entrance doors where a traditional door frame and conventional hinges are not required.

Solid Investment-Cast Construction

A major feature of this model is its solid precision-cast stainless steel body.

Investment casting allows the fitting to form a strong, integrated structure while maintaining accurate dimensions for the pivot and floor spring connection.

This construction is especially useful for glass door applications where the bottom fitting must repeatedly carry and transfer the weight of the door during opening and closing.

The AISI 304 stainless steel construction also provides good durability and corrosion resistance for standard indoor commercial environments.

Designed for Double-Action Glass Doors

This bottom patch fitting is suitable for double-acting glass doors.

That means the door system can be configured to swing in both directions when used with a compatible floor spring.

The fitting is also non-handed, allowing it to be used for either:

Left-hand doors
sau
Right-hand doors

This gives glass door fabricators and project contractors more flexibility when planning installation.

Tempered Glass Compatibility

The fitting is designed for tempered glass doors.

Depending on the exact fitting dimensions and installation configuration, it can be used with glass in the 8–12mm range, în timp ce 10mm tempered glass is the common standard configuration for this type of system.

For projects using other glass thicknesses within the supported range, the glass cut-out dimensions and fitting compatibility should be confirmed before glass processing.

Important Glass Note

This fitting is not intended for use with laminated glass.

The glass type should therefore be confirmed before production, drilling or cut-out processing.

This is particularly important because patch fittings normally require accurately processed glass cut-outs.

Recommended Door Size Guidelines

For the stated hardware configuration, the following limits should be used as a reference:

Maximum Door Height:
102 in / 2591mm

Maximum Door Width:
42 in / 1092mm

Maximum Door Weight:
194 lbs / 88kg

Common Glass Thickness:
10mm tempered glass

The actual allowable door size can also depend on the complete floor spring system, installation conditions, glass processing accuracy and other connected hardware.

For project orders, the full door dimensions and door weight should be confirmed before selecting the fitting and floor spring combination.

Surface Finish Options

Three standard surface treatments are available:

Mirror Polished
Provides a reflective stainless steel finish suitable for polished architectural hardware.

Satinat
Creates a softer brushed appearance commonly used in commercial glass door systems.

Black
Suitable for modern black-framed or contemporary architectural designs.

For projects involving multiple patch fittings, handles and floor spring accessories, matching the surface finish across the complete hardware set helps maintain a consistent appearance.

Typical Applications

Acest AISI 304 bottom door patch fitting is suitable for frameless glass doors used in:

• Office entrances
• Hoteluri
• Apartment buildings
• Clădiri comerciale
• Shopping areas
• Interior glass entrances
• Reception areas
• Sisteme de uși din sticlă fără ramă

It is particularly suitable for projects requiring a clean architectural appearance with the door closing mechanism concealed in the floor.

Installation and Selection Notes

Before ordering, buyers should confirm the complete door system rather than selecting the bottom patch fitting independently.

Important information includes:

Glass thickness and type — tempered glass only.

Door weight and dimensions — should remain within the system limits.

Floor spring model — the pivot interface must be compatible with the bottom insert.

Glass cut-out — dimensions should be confirmed before glass processing.

Finisajul suprafeței — should match the top patch, handle and other visible hardware where possible.

This approach helps prevent incompatibility between the floor spring, glass processing and patch fitting during installation.
