These two-piece fasteners are pre-assembled and offer a simple and versatile method of bundling and mounting cables runing perpendicular to 9x17 oval mounting holes. The fir tree base will easily push into pre-punched holes in panels or threaded blind holes and offers a secure fit. The two-piece design enables the head of the tie to be oriented to the required position to ease assembly, while the disc on top of the fir tree covers the hole and minimizes the ingress of water and dirt.
