These sleek, easy-to-install guides optimize the positioning and comfort of chest and shoulder harness straps on almost any backrest, while enabling the use of harnesses on more chairs. The thin, stylish design with long mounting slots is widely compatible with different harnesses, pull-styles and end fittings. Optional Mounting Adapter plates provide even more mounting and adjustment possibilities. Details include built-in threaded holes that allow attachment of harness end fittings directly to strap guides.
