Clamping Collar OBO Bettermann ASL 733 63 Aluminum with Long Hole

Clamping Collar OBO Bettermann ASL 733 63 Aluminum with Long Hole is a durable aluminum pipe and conduit collar designed for secure fixation in electrical and mechanical installations. The collar’s elongated hole allows adjustable mounting positions along a fastening screw or bolt, enabling precise alignment and easy on-site adjustments. Made from aluminum, the clamp offers good corrosion resistance and a lightweight profile suitable for indoor and sheltered outdoor use where non-magnetic and low-weight components are preferred.

Advantages

The ASL 733 63 collar provides a rigid connection between pipe or conduit and the supporting structure while permitting fine positional adjustment via its long hole. Aluminum construction ensures reduced weight compared with steel alternatives and offers natural resistance to corrosion without additional coatings. The simple form factor and standardized mounting allow quick installation and compatibility with common fastening hardware. Its smooth interior and formed profile reduce point stress on conduits and cables.

Suitable for

• Fixing electrical conduits and metal or plastic pipes to walls, ceilings, and frames
• Installations requiring adjustable alignment during mounting
• Lightweight mechanical fastening where corrosion resistance is needed

Key specifications

• Material: Aluminum
• Type: Clamping collar with elongated (long) hole for adjustable mounting
• Intended application: Pipe and conduit fastening for electrical and mechanical installations
• Fixation: Single-screw or bolt mounting through elongated hole
• Profile: Formed collar for stable grip and reduced point stress

How to use

Place the collar around the pipe or conduit so the formed section grips the outer surface evenly. Align the elongated hole over the chosen mounting point on the support surface, insert a suitable screw or bolt, and tighten to secure the collar. Use the elongated hole to adjust lateral position before fully tightening. Ensure the selected screw or bolt is compatible with the mounting surface and load requirements. For multiple supports, space collars at intervals appropriate to the pipe material and diameter to prevent sagging.

Usage recommendations

Choose corrosion-resistant fasteners in environments with increased humidity or corrosive agents. Verify load and spacing recommendations for the specific conduit or pipe type; avoid over-tightening to prevent deformation of the collar or damage to the conduit. For outdoor exposed installations, consider additional protective measures if direct weather exposure is expected.
