A Double Sided Mesh Panel Clip or A72 functions in a similar way to a Single Sided Mesh Panel Clip (A70), but with the difference that it can allow mesh panels to be attached to both sides of a tube within guardrail structures. It is made from steel and can fix the outer rods (8mm maximum thickness) of mesh panels with two ‘horseshoe’ shaped pieces that come with the fitting. One tube with an outside diameter of 48.3mm (Size 8) is required and can pass through the centre of this fitting. It is also able to fix panels of other materials like plywood or perspex (thickness must be no more than 10mm), but the two small ‘horseshoe’ end parts will not be needed for this. You should space Double Sided Mesh Panel Clips no more than 450mm apart.
A Single Sided Mesh Panel Clip (A70) can be used if a mesh panel only needs to be connected to a single side of a tube.
