OTC Comfort Pull Lumbar Sacral SupportThe OTC 2880 lumbosacral support has a completely non elastic construction for optimum support. Key feature of this support is its rigid back panel with a simultaneous roller pulling tightening apparatus and drawstring pulls that provides symmetrical compressive support for the entire lower back. The wearer can independently adjust the top and bottom of the brace to provide localized compression where it is needed for maximum pain relief.
