Pipe Mount Bracket ALPAR U50 for 50 mm Pipe on Spiral Post (Fi 50)

ALPAR U50 is a pipe mount bracket designed to secure a 50 mm (Fi 50) cylindrical pipe to a spiral or threaded post. The component creates a stable mechanical connection between the pipe and a spun post surface, allowing mounting of handrails, barrier elements, signage supports or other light structural attachments where a 50 mm pipe interface is required. The bracket is supplied as model U50 by ALPAR and is intended for use in outdoor or indoor metalwork installations that use spiral posts.

Advantages

The bracket provides a precise fit for 50 mm pipes and a reliable clamping surface against spiral posts, reducing lateral movement and maintaining alignment. It simplifies installation by matching the pipe diameter and the post profile, eliminating the need for complex on-site modifications. The design ensures repeatable positioning and can be combined with standard fasteners for secure mechanical fixation.

Suitable for

• Mounting handrails and guardrails on spiral/threaded posts
• Fixing signage or directional plates to spun posts
• Attaching light barriers or boundary elements to post systems
• Repairing or replacing existing 50 mm pipe connections on spiral posts

Key specifications

• Pipe nominal diameter compatibility: 50 mm (Fi 50)
• Intended post type: spiral / spun / threaded post profile
• Function: mechanical bracket for axial and radial stabilization of cylindrical pipes
• Typical use: mounting of railings, barriers, signs and light structural attachments
• Material and finish: metal construction suitable for structural mounting (verify specific finish before installation)

How to use

Position the ALPAR U50 bracket so that the internal surface conforms to the 50 mm pipe and aligns with the spiral post profile. Slide or place the pipe into the bracket, align the assembly on the post, then secure using appropriate fasteners through the bracket and into the post or using bolts compatible with the post threading. Ensure that fasteners are tightened to the torque recommended for the chosen bolt size and material. Verify alignment and adjust before final tightening. For outdoor installations, use corrosion-resistant fasteners and check compatibility with the post surface.

Usage recommendations

Inspect mating surfaces for damage or excessive corrosion prior to installation. Use fasteners and torque values appropriate for the structural loads expected; consult a structural engineer when used in load-bearing or safety-critical applications. For long-term durability in exterior environments select corrosion-resistant hardware and periodically check tightness and condition.
