These assemblies consist of a cable tie and a weld stud mounting base - supplied pre-assembled for ease and speed of installation they allow the tie head to be rotated into the perfect position for installation. All types feature a 'soft-push' design - no tools are required to fit the parts to the stud. The SBH type is specifically designed to not only secure cable bundles but the 'mushroom-shape' of the fixing allows for installation and securing of insulation or a sound deadening blanket. The SBS types are ideal for installation onto the stud prior to attaching the cable. (ie. No lateral tolerances required). The SB5 types are designed to allow a lateral tolerance for the fixing point. (ie. Where the cable tie is attached to the harness before fixing to the stud and possible miss-alignment can occur and some lateral tolerance is require
