The Interna-Rail handrail system from Hollaender Manufacturing (Cincinnati, OH) is an in-line fitting based system designed to combine the look of a welded rail with all the benefits of a mechanical system. The system can be designed to meet any building code. Its fittings are manufactured from 6063-T6 aluminum alloy and the pipe is a combination of 6005-T5 and 6063-T6 alloys. All Interna-Rail fittings and pipe can be supplied with either a 215-R1 anodized finish, or a powder coat finish that meets AAMA 2604 specifications for color and gloss retention.
