The RULBK1-52 is an adhesive rack unit label kit that numbers rack rails from 1U at the top down to 52U at the bottom, giving IT, AV and industrial installers a clear elevation reference on every rail. It is sold as a two-roll pack so both rack rails — front and rear, or left and right — can be marked in a single kit.
Each label strip is 91.00 in (2311 mm) long and 0.25 in (6 mm) wide and is made from durable polyester with high-contrast white lettering on a black background for long-lasting rack unit identification. The peel-and-stick adhesive backing installs without tools or hardware, and the cut-to-size design lets the strip be trimmed for a clean, customized fit on shorter rails.
Designed to fit rack rails up to 52RU, RULBK1-52 suits most industry-standard 19-inch and 23-inch open frame racks and cabinets and is not limited to Hammond products, making it equally useful for new deployments and retrofit projects. Clear rack unit markings reduce installation errors during equipment deployment and make later additions, moves and maintenance faster to plan and document.
The kit is manufactured to Hammond's quality standards and is RoHS and REACH compliant. It is made in Canada (country of origin CA), is USMCA compliant, and ships under tariff code 7318.15.8085 with ECCN EAR99. Choose RULBK1-52 for top-down (ascending) numbering; a descending version is offered in the same series.
