4-Hole Mast Clamp for Ø 48–50 mm Tubes – 3 mm Galvanised Steel
The AS46051 is a robust 4-hole mast clamp designed to secure antenna and satellite mast tubes with an outside diameter of 48 to 50 mm.
It is particularly suitable for installations where a mast tube needs to be fixed to a load-bearing roof rafter, timber beam or another appropriate supporting structure.
The clamp is manufactured from 3 mm quality steel sheet and features a galvanised surface.
Two 8 × 50 mm wood screws are included.
Suitable for Ø 48–50 mm mast tubes
The clamp is designed for round mast tubes with an outside diameter between 48 and 50 mm.
Typical applications include:
satellite antenna masts
DVB-T/T2 antenna installations
terrestrial antennas
directional antennas
suitable radio antenna systems
other compatible mast structures
The actual mast diameter should always be checked before installation.
Four-hole mounting design
The bracket features four mounting holes for secure attachment to a suitable supporting structure.
This provides several fixing points and supports a stable connection between the mast and mounting substrate.
3 mm quality steel sheet
The clamp is manufactured from 3 mm thick quality steel sheet.
The robust construction provides a solid mechanical base for typical antenna and mast installations.
Galvanised surface
The steel surface is galvanised to provide basic corrosion protection for typical antenna and technical installation environments.
Two 8 × 50 mm wood screws included
Two wood screws are supplied with the clamp.
They can be used with suitable load-bearing timber substrates where appropriate.
For concrete, masonry, metal or other materials, suitable mounting hardware must be selected separately.
Typical applications
The AS46051 can be used for:
satellite mast installations
antenna mast mounting
roof rafter installations
replacement of existing mast clamps
repair and retrofit work
technical tube fixing applications
Mechanical load considerations
The stability of the finished installation depends on the complete system.
Important factors include:
mast diameter
unsupported mast length
antenna size
antenna weight
wind surface area
supporting structure
mounting hardware
installation location
