Product Advice: How to Install Cantilever Arms

Cantilever arms fixed to a wall.

Cantilever arms are a structural fitting made from steel that, when anchored to a wall or surface, provide support to objects and infrastructure. Therefore, ideal for supporting HVAC units or cable tray, cantilever arms offer a quick and easy method of support and sometimes storage.

The structural support unit is fixed at one end only and the load is held by the protruding metal bar.  The weight of the load held by the ‘arm’ is transferred into the supporting base/surface, this ensures strong weight-bearing capacity.

Cantilever arms are available in single and double styles providing greater weight-bearing ability because of the reinforced depth of the metal.

Cantilever arms are available in lengths from 150mm to 900mm in the single-arm type and 450mm, 600mm and 750mm lengths in the double.  However, the size of the AC unit or channel will determine which length of the cantilever arm you need.

How to Install Cantilever Arms?

so, cantilever arms can be installed in many ways to work with different surface structures. For a racking style, they can be connected to metal uprights with bolts and based on size and requirements, can be inserted on a slotted upright strut.

Cantilever arms are suitable to be installed on any surface with the correct fixings.  Such as loose bolt shield anchors as these work with brick, concrete and stone.

The steel composition of the cantilever arms enables them to retain their strength for long periods.  While remaining low maintenance with their rust-resistant HDG coating and smooth surface.

We recommend medium to heavy-duty anchors for the best peace of mind as these offer the most tensile strength for larger loads.

The stainless steel through-bolt anchor provides high performance through concrete for a stronghold. Sleeve bolt anchors offer an elongated expansion sleeve, making it suitable for use in brickwork.

So, to make fixing cantilever arms even easier, Armaflo stock condenser wall units to ensure your work is ready-to-go and simple to fit.  They are fully adjustable on the width and with the two sizes of arms, can take any unit up to 600mm deep.

Each kit contains:
  • 2 x slotted 41 x 41mm channel – 750mm
  • 2 x cantilever arms (450mm or 600mm)
  • 2 x black end caps
  • 8 x M10 x 25 penny washers
  • 8 x M10 plain channel nuts
  • 8 x M10 x 30 set screws
  • 4 x M10 x 40 penny washers
  • 4 x M10 x 75 loose bolt shield anchor

Cantilever arms are suitable for installation on walls, ceilings and free-standing structures. This gives electricians and installers a better opportunity to get the best spot for application.

Lastly, with great weight-bearing capacity, they are the ideal solution for cable management, storage and system support.

With strength in design and versatility in application, you can work with the layout of a project and with a bolt-and-fix approach.  The installation process is simple.
