Collare per palo ShiverPeaks 89855 acciaio zincato con scanalature di serraggio aggiuntive

Mast clamp ShiverPeaks 89855 galvanized steel with additional clamping grooves is a robust fastening solution for securing masts and poles in marine, antenna and general rigging installations. The clamp is manufactured from galvanized steel to provide protection against corrosion and features extra clamping grooves that improve grip on round or slightly profiled mast surfaces. Designed for reliable mechanical fastening, it supports stable mounting where wind, vibration or movement can affect fixture integrity.

Advantages

The galvanized steel construction offers enhanced resistance to rust in outdoor and marine environments while maintaining mechanical strength. Additional clamping grooves distribute clamping force more evenly and reduce slippage on cylindrical surfaces. The simple two-piece design allows for straightforward installation and consistent, repeatable torque values. Its compatibility with standard mast diameters makes it a versatile choice for different rigging setups.

Suitable for

• Securing marine masts, poles and spars
• Mounting antennas and aerials on round masts
• General rigging and temporary installations where corrosion resistance is required
• Applications requiring a stable mechanical connection on slightly profiled or smooth tubular surfaces

Key specifications

• Material: galvanized steel for improved corrosion protection
• Design: two-piece clamp with additional clamping grooves for enhanced grip
• Compatible mast diameter: suitable for round or slightly profiled tubes in the 40–42 mm range
• Surface finish: zinc galvanization to resist environmental exposure

How to use

Position the two halves of the mast clamp around the mast or tube so the additional clamping grooves engage the surface. Insert and tighten the fastening bolts evenly, alternating between bolts to achieve uniform clamping pressure and to avoid distortion. Apply recommended torque according to the bolt size used; check that the clamp sits flush and does not compress or damage the mast surface. Periodically inspect the clamp for tightness and corrosion, especially in marine applications, and retighten or replace components as needed.

Recommendations

For best performance, use stainless or appropriately rated bolts compatible with the galvanized finish, and apply anti-seize or compatible thread lubricant in corrosive environments. Avoid overtightening which can deform the mast profile; aim for a secure, non-slip fit while preserving the integrity of the mast surface.
