Glass clamp fastening: Professional solutions for modern glass railings

Discover the versatile clamp fixings from Bohle for professional glass railings. Mounted without drilling holes in the glass, they offer maximum safety with minimum installation time.


The variety of glass clamp holders: optimum solutions for every requirement

Specialist companies in the glass and metal construction sector are regularly faced with the challenge of realising individual customer requirements in a safe and visually appealing way. Clamp fasteners for glass offer decisive advantages that make work processes more efficient and lead to high-quality end results.

Glass clamps and glass clamp holders are the indispensable link for glass panelling in stainless steel railings and impress with their versatility. The extensive range of clamp fixings includes various shapes and sizes:

  • Semicircular versions in 50 × 40 mm and 63 × 45 mm
  • Square versions in 45 × 45 mm, 55 × 55 mm and 70 × 55 mm (narrow and wide)
This variety enables optimum adaptation to different glass thicknesses from 6 mm to 21.52 mm and offers the right solution for both toughened safety glass (TSG) and laminated safety glass (LSG). The clamp fixings score particularly highly thanks to their simple installation and the ability to achieve spans of up to two metres with just four clamps per pane.

Technical advantages of the clamp fastening for glass

Glass clamp brackets offer decisive technical advantages over conventional fixing systems:

Hole-free installation

The biggest advantage of the clamp fastening is the drill-free installation. In contrast to point fixings, glass clamps do not require any holes to be drilled in the glass, which not only simplifies installation but also preserves the structural integrity of the glass. This significantly increases the stability and durability of the entire construction.

Flexible adaptation to different glass thicknesses

Separately available rubber inserts allow the clamps to be optimally adapted to different glass thicknesses. The inserts can simply be pressed into the clamp mountings without the need for gluing. This precise adjustment to the respective glass thickness ensures an ideal hold for the glass pane.

Optimum safety

Safety is the top priority when installing guardrails. Bohle clamp fixings comply with all current standards and guidelines for balustrades and guardrails. Especially when using laminated safety glass (LSG), additional safety plates ensure optimum protection against slipping. These can be easily inserted into the clamp fixings without the need for additional glass processing.


High material quality for long-lasting functionality

Different material qualities are available depending on the area of application:

  • Die-cast zinc in chrome-plated or brushed stainless steel look for indoor areas
  • Stainless steel V2A (AISI 304) for indoor areas with increased requirements
  • Stainless steel V4A (AISI 316) for outdoor areas and particularly demanding environments
The V4A quality versions offer optimum protection against corrosion, even in demanding environments with chlorine or salt water, and thus ensure a long service life for the glass fittings.

Areas of application for clamp holders and glass clamps

Whether on balconies, terraces, stairs or galleries - glass railings with clamp fixings provide a transparent view with maximum safety. Thanks to the various tube connections, the Bohle clamp fastenings can be mounted on all standard railing posts (square, Ø 42.4 mm round and Ø 48.3 mm round tubes) both indoors and outdoors.

Fall protection in commercial and residential buildings

For fall protection in elevated areas such as galleries, atriums or staircases, clamp brackets offer a safe and aesthetically pleasing solution. The systems are designed for different load classes and offer resistance to horizontal forces of 0.5 kN/m to 2.0 kN/m, depending on the design.

Windbreak and privacy screen elements

In outdoor areas, glass elements with clamp fastening provide elegant wind and privacy protection. Particularly on patios and in garden areas, they allow an uninterrupted view while providing protection from wind and weather.

Room dividers and partitions

In interior design, clamping profiles for glass are used to create transparent room partitions. They provide a clear visual demarcation without visually reducing the size of the room or impairing the flow of light.


Frequently asked questions about clamp fastenings for glass

Both toughened safety glass (TSG) and laminated safety glass (LSG) can be fixed with clamp brackets. Depending on the model, the Bohle clamp fixings support glass thicknesses from 6 mm to 21.52 mm, with special rubber inserts available for each glass thickness. Additional anti-slip protection is required for laminated safety glass.


The main difference lies in the installation: while clamp fixings do not require drill holes in the glass, point fixings need pre-drilled holes. Clamp fixings offer the advantage of simpler installation on a post, while point fixings enable a particularly delicate look and can be positioned more flexibly.


Bohle clamp fastenings impress with their versatile connection options, high-quality materials and precise workmanship. With just four clamp fixings per pane, spans of up to two metres can be achieved, enabling generous and transparent railing solutions. The rubber inserts, which are available separately, also offer flexible combination options for clamp fixings and glass.


A certain degree of fine adjustment is possible due to the design of the clamps and the installation technique. The panes should be inserted in such a way that the glass edge has a uniform clearance of approx. 2 mm to the back of the clamp, so that movement due to temperature fluctuations can also be compensated for.


For outdoor applications, the use of V4A (AISI 316) stainless steel clamp fixings is recommended. This high-quality stainless steel alloy offers optimum protection against corrosion even under extreme conditions such as salt or chlorinated water and ensures long-lasting functionality and appearance.

Use the extensive product range of Bohle glass fittings and glass railings to offer your customers customised and safe solutions. With the right clamp fixings, you can create not only technically flawless, but also visually impressive glass installations that fulfil the highest standards of safety and design.
