Now with the hinge at its base and click-lock at topside, one easy way to affix D-Line trunking is to gently peel the liner at one end from its backing tape, hold up the trunking length(s), and apply finger pressure to stick the first inches up to the pencil mark.
Then slowly move along the length(s); peeling, pressing and firmly sticking the D-Line trunkings as as you go. Finally insert the cables, and attach any accessories. Job done!
Assuming the surface was clean and level flat, not dusty and uneven or textured, then at normal room temperatures you’ll have created a bond that should last for years.
Alternatively, D-Line trunking can be drilled and screw-fixed, with the choice of fixing being dependent on the type of surface.
