OBO ASL 733 44 G Spacer Clamp with Elongated Hole, 36-44 mm, Electro-Galvanized Steel

Electricians and pipe fitters often need a reliable way to secure cables, pipes, or conduits at a fixed distance from a wall or ceiling. The OBO ASL 733 44 G spacer clamp solves this by providing a 20 mm stand-off, keeping installations neat and allowing for air circulation or easy cleaning behind the line. Its elongated mounting hole gives you wiggle room during alignment, making it forgiving when drill holes are slightly off. Made from electro-galvanized steel, it resists corrosion in dry indoor environments, ensuring a long service life. The clamp accommodates diameters from 36 to 44 mm, covering a range of common cable bundles and pipe sizes.

Key specifications

• Clamping diameter range: 36–44 mm
• Material: Electro-galvanized steel
• Mounting hole type: Elongated hole (7 x 20 mm)
• Distance to mounting surface: 20 mm
• Recommended screw diameter: M6
• Overall dimensions (L x W x H): 60 x 20 x 44 mm

Why choose it

The galvanized finish provides solid corrosion protection, so the clamp stays reliable even in mildly humid conditions. The elongated hole simplifies installation—you can adjust the position before final tightening. The 20 mm spacer height keeps cables away from the surface, reducing the risk of moisture buildup and making maintenance easier. It’s a robust, no-nonsense solution for professional electrical and mechanical installations.

Ideal use cases

• Securing cable bundles along walls in commercial buildings
• Mounting pipes or conduits in dry indoor areas
• Creating a defined gap for thermal insulation or airflow
• Retrofitting installations where hole positions may vary

Good to know

The clamp is part of the OBO ASL 733 series, known for dependable fastening components. It is designed for single-point fastening with an M6 screw (not included). Always verify that the diameter of your cable or pipe falls within the 36–44 mm range for a secure fit. For outdoor or wet environments, consider additional corrosion protection measures.
