## Summary description

Mast clamp ShiverPeaks 89856 is a galvanized steel clamp designed to secure masts, poles or tubing. It features additional clamping grooves for improved grip and stability and is suitable for marine, antenna or flagpole installations where corrosion resistance and reliable fastening are required.

## Long description

The Mast clamp ShiverPeaks 89856 galvanized steel with additional clamping grooves is a robust fastening solution for securing masts, poles and tubing in outdoor environments. Manufactured from galvanized steel, this clamp combines corrosion resistance with mechanical strength to provide reliable attachment points for marine fittings, antenna masts and flagpoles. The design includes additional clamping grooves that increase friction and distribute clamping force more evenly, reducing slippage on cylindrical supports with a nominal diameter suited to 48–50 mm tubing.
Advantages
This galvanized mast clamp offers enhanced grip thanks to integrated extra clamping grooves that improve contact with the mast surface and reduce rotational movement under load. Galvanized steel construction provides long-term protection against rust and environmental wear, making the clamp suitable for saline or humid conditions. The clamp’s geometry ensures a secure fit on round tubing while allowing straightforward installation and maintenance without specialized tools.
Suitable for
Securing antenna masts on rooftops and towers
Mounting flagpoles and banners in outdoor settings
Fixing marine fittings and accessories on boats and piers
Clamping scaffolding, railings or temporary tubing with 48–50 mm diameter
Key specifications
Material: galvanized steel for corrosion resistance
Design: split clamp with additional clamping grooves for improved grip
Suitable tube diameter: nominally for 48–50 mm round tubing
Application environment: outdoor, marine and antenna installations
Mounting: external clamp providing distributed clamping force
How to use
Position the clamp around the mast or tubing so the clamping grooves contact the cylindrical surface. Align the two clamping halves and insert the fastening bolts or screws through the provided holes. Tighten the fasteners gradually and evenly to compress both halves against the mast until the clamp holds securely without deforming the tube. For marine or exposed installations, check bolt torque periodically and re-tighten if necessary to compensate for vibration, thermal cycling or settling.
Usage recommendations
For best performance, use stainless or corrosion-resistant fasteners and apply anti-seize compound on threads in corrosive environments. Inspect the clamp and mounting hardware at regular intervals and replace any components that show significant corrosion or wear. Ensure the clamped tube diameter is within the 48–50 mm range to maintain proper grip and avoid over-tightening that could damage the tubing.
