A mechanical system with a continual, sleek, symmetrical look that needs no welding or threading. Hollaender’s A.D.A. Interna-Rail is a modular solution engineered to allow quick “build from scratch” on-site installation, or to modify an existing handrail, to comply with the requirements of Americans with Disabilities Act (ADA) and the Uniform Federal Accessibility Standards (UFAS). The design provides an excellent continuous gripping surface along the entire run of the top rail. The high-quality components with the weather and wear-resistant anodized satin finish do not rust or deteriorate, resulting in very low long-term maintenance costs.
