Designed, tested and manufactured in accordance with IEC 61914
Inserts
Stacked formation
Twist-foot base
This product can be stacked a maximum of three high by using the twist foot variant. This version locks into the recess provided in the top of the clamps. Due to tolerances of standard unistrut style profile, Ellis recommend using fixings to fasten the clamp to the channel.
Note: the cleat range is covered by a set of inserts that sit inside the main body, therefore all outside dimensions are the same. *NBC45-55 does not use inserts. The product is registered with Network Rail PADS System as an uncontrolled item, as such it is not searchable on PADS. PADS numbers are for the twist foot version of the product.
