Use this hang track rail to support the 50mm pitch twinslot wall uprights either the 1195mm or the longest 1995mm for your adjustable shelf project. Use 3 wall uprights and the 1690mm length hang track if fitting two rows of 800mm length gridboard wire shelves or the liteboards side by side on your shelf installation.
Fit the hangtrack rail to studs in a stud wall if possible, extra holes should be drilled in the hang track rail to coincide with wall studs if required. (recommended). Use quality hollow wall anchors here if fitting only to gyprock walls, or use the wall anchors into the holes which are not ftted to studs in a cavity wall installation.
