The single-lap mounting clamp 604 19 G from OBO Bettermann is a robust fastening element for cables and pipes in the field of electrical and installation mounting. It is used for the secure anchoring of lines and pipe systems to substrates such as concrete, masonry or metal. The clamp is made of steel and designed for fastening with suitable tools, with certain size restrictions applying when using gas-powered nailers or stud setters.

Mounting clamp

The clamp is designed as a single-lap type, meaning it consists of a single, bent metal strip that wraps around the object to be fastened and is closed via an opening. This design enables quick and secure installation, especially for cables and pipes of medium to small diameter. The material thickness and shape ensure sufficient holding force and mechanical stability.

Applications

The clamp is suitable for use in electrical installation, building and industrial cable routing, as well as in piping technology. It is frequently used for securing electrical lines, data cables or small pipe systems to walls, ceilings or beams. It can be used in both indoor and outdoor environments, although the material (steel) does not provide special corrosion protection — additional coating or covering is required in damp or aggressive environments.

Functions and equipment in detail

The clamp has a nominal size of 19 mm, indicating the maximum diameter that can be securely fastened. The single-lap construction allows for easy handling and quick installation, especially for repeated fastening tasks. The clamp’s opening is closed using a suitable tool; the use of gas-powered nailers is not recommended for sizes 3 and 4. Similarly, stud setters are not suitable for sizes 3 to 21, due to the mechanical load capacity and construction of the clamp.

Technology explained simply

The locking mechanism is achieved via a closure system that operates through an opening in the clamp body. The material thickness and shape ensure sufficient strength to transmit the loads from the fastened lines or pipes. The clamp is neither galvanised nor coated, which requires additional protective measures in damp or corrosive environments.

Compatibility and accessories

The clamp is designed for fastening cables and pipes with a diameter up to 19 mm. It can be installed using appropriate fastening tools such as screwdrivers, pliers or special clamp presses. The use of gas-powered nailers is not suitable for sizes 3 and 4, and stud setters are not intended for sizes 3 to 21.

Installation and mounting

Installation is carried out by placing the clamp around the cable or pipe to be fastened and closing the opening using a suitable tool. The clamp is positioned at the desired location on the substrate, which should be clean and flat. The use of gas-powered nailers or stud setters is not intended for the specified size restrictions, due to the mechanical load capacity of the clamp. Installation is performed without additional tools or connecting elements.

Operational advantages

The single-lap mounting clamp offers quick and secure installation, especially for repeated fastening tasks. The robust steel construction ensures high mechanical stability and durability. Its simple handling and universal applicability in various installation scenarios make it a reliable fastening element in electrical and installation construction. The nominal size of 19 mm allows for the fastening of a wide range of cables and pipes in the medium diameter range.
