The ASL 733 25 G spacing bracket from OBO Bettermann is designed for the secure mounting of pipes and cables on walls, ceilings, and floors. It is specifically designed for use in electrical and technical installations where stable and durable mounting is required. The product features a self-locking upper part that ensures secure anchoring of the object to be mounted, without requiring additional holding or tensioning devices. Mounting is achieved via a long slot, which allows for flexible positioning and adaptation to different installation conditions.

Spacing bracket is the product type described here. It serves as a mechanical holder for conduits and pipes in the installation sector. The functionality retention approval according to DIN 4102 Part 12 is a central feature that highlights its suitability for use in fire protection systems. The bracket is approved for functionality retention classes E 30 to E 90, meaning it maintains its function even under increased thermal stress in the event of a fire. This is particularly relevant in buildings where continuous power supply or the operation of emergency lighting, alarm systems, or fire protection systems must be ensured even during a fire.

Self-locking upper part ensures that the conduit or pipe to be mounted is automatically secured after insertion. This reduces the risk of accidental displacement or loosening during operation. The mounting via long slot allows for variable positioning of the bracket on the substrate, enabling adaptation to different drilling or mounting points. This is particularly advantageous during installation in existing structures, where exact positioning is often not precisely defined.

The bracket is designed for pipes and cables with a diameter of 20 to 25 mm. This dimension makes it suitable for a wide range of standard conduits in the electrical and building technology sectors. The material is steel, ensuring high mechanical strength and durability. The surface is galvanized, providing corrosion protection and extending service life in both outdoor and indoor environments.

Compatibility is ensured for all applications requiring the mounting of pipes or cables with a diameter of 20 to 25 mm. The bracket can be mounted on various substrates, provided they offer suitable mounting options (e.g., screws, anchors). Use in fire protection systems is secured by the approval according to DIN 4102 Part 12, allowing it to be used in areas with increased fire safety requirements.

Installation is carried out by simply inserting the pipe or cable into the bracket and then securing it to the substrate via the long slot. The screw connection is tightened so that the bracket is firmly attached to the substrate without damaging the object being mounted. The self-locking function ensures that the object cannot fall out after insertion.

Operational advantages include easy installation, high mechanical stability, and approval for functionality retention. The bracket requires no additional holding or tensioning devices, which reduces installation time and improves workflow efficiency. The galvanized surface ensures long service life, even in damp or corrosive environments.
