Make it easy by choosing a radius for your fittings to work around your project design, not the other way around…
A radius in a cable support fitting is the size of an arc or bend. It is not the angle, rather it is the distance from the start of the angle to the end. Imagine a 90° ladder bend, the radius is the distance from where your cables enter the arc of the bend to where they leave it.
A smaller radius size might mean that a fitting will support your cables over a 90° angle for example over a short distance, whereas a larger radius can result in more of a ‘sweeping bend’ over a longer distance.
Any cable support fitting that supports cables over a curve, such as a ladder bend, tee, cross, or riser has some measurements that are measured with a radius.
Crosses or tee fittings obviously have this measurement in more than one place.
Most of the EzyStrut ladder fittings have a standard radius of 300 (NEMA 1 Steel) or 450mm (most other ladders). However, it is easy for us to offer a customised radius size, normally they can be 300, 450, 600, 900 or other sizes, measured in mm, depending on other specifications of the fitting.
Some examples on radius measurements for ladder fittings are pictured below:
Customised sizes are easy for us to arrange, test the design for and produce quickly. Often you might specify a customised size to work around obstacles in your project’s design that a standard size wouldn’t work with.
If you are working with EzyTrays or EzyMesh, it is very easy for you to customise the radius of bends or risers because you create them yourself by cutting the tray/mesh and then fitting the relevant accessories to secure it in shape. Instructions for doing this can generally be found in our catalogues.
