Mounting Bracket ALPAR U1 U103T for Spiral Post Ø25–46 mm

ALPAR U1 U103T mounting bracket is designed to clamp securely to spiral (wirowany) round posts with outer diameters from 25 to 46 mm. The bracket provides a stable platform for attaching fixtures and accessories to tubular metal posts commonly found in fencing, signage posts and outdoor structures. Constructed for straightforward installation, this bracket suits applications where a reliable clamp to a cylindrical post is required.

Advantages

The bracket offers firm mechanical grip on round posts within the specified diameter range, reducing movement of the attached fixtures. Its design allows quick installation without the need for complex modifications to the post, enabling efficient mounting of various accessories. Engineered for outdoor use, it provides consistent support and alignment for mounted elements on spiral posts.

Suitable for

• Mounting signs, plates or small fixtures on round metal posts
• Attaching accessories to fence posts and barrier systems
• Fixing lights, reflectors or sensors to tubular outdoor supports
• Temporary or permanent installations where a clamp-on solution is preferred

When it may not be suitable

This bracket is intended for use with circular posts whose outer diameter falls between 25 mm and 46 mm; it is not suitable for posts outside this diameter range or for square, rectangular, or highly irregular cross-sections. It may also be unsuitable where load requirements exceed the bracket's intended capacity or where engineers specify welded or through-bolt connections for structural safety.

Key specifications

• Compatible post outer diameter: 25–46 mm
• Application type: clamp-on bracket for spiral/round posts
• Material and finish: designed for metal post attachment (see manufacturer for material details)
• Primary use environments: outdoor posts, fencing, signage supports

How to use

Position the bracket around the round post at the chosen mounting height and align the bracket so the attached fixture will be level. Tighten the bracket's clamping mechanism evenly until the bracket holds securely against the post while avoiding overtightening that could deform the post or bracket. Attach the intended fixture to the bracket using appropriate fasteners and check that the assembly is stable and aligned before finalizing the installation.

What to consider before purchase

• Confirm the outer diameter of your post is within 25–46 mm
• Verify that the load and environmental conditions match the bracket's intended use
• Check compatibility of the bracket's attachment points with the fixture you plan to mount
• Consider corrosion protection requirements for outdoor installations

Usage recommendations

For best results, inspect the post surface for damage or excessive irregularity before installation, use appropriate corrosion-resistant fasteners for outdoor environments, and periodically check the clamping tightness as part of routine maintenance.
