39731-001

The 39731 rail grommet kit is engineered for ZetaFrame® cabinets and delivers a reliable seal for equipment mounting rails. Each kit contains eight flexible plastic grommets that act as railroad track grommets, allowing users to trim them to fit any cable diameter. By covering cable openings, the kit helps maintain consistent airflow and protects equipment from dust ingress. Designed as a grommet cabinet accessory, the kit integrates seamlessly with the modular construction of ZetaFrame® systems. The plastic material is UL®‑94 V0 rated, ensuring a high level of fire safety without compromising flexibility. Installation requires only standard tools and can be performed in the field to accelerate deployment. The grommets are sized for 27.6‑inch (700 mm) and 29.5‑inch (750 mm) cabinet widths, providing a versatile solution for most data‑center and edge environments. They are not compatible with 23.6‑inch (600 mm) cabinets, which helps avoid mismatched components during planning. The secure fit reduces air turbulence around cables, contributing to more efficient cooling. By eliminating uncontrolled airflow paths, the 39731 kit supports the overall thermal management strategy of high‑density installations. Improved airflow control can lower cooling costs and extend the life of sensitive electronics. The kit's low‑profile design also maximizes usable interior space for additional equipment. CPI's global network of authorized distributors ensures rapid availability of the 39731 rail grommet kit worldwide. Technical support and detailed documentation, including a spec sheet and user manual, are available to guide users through selection and installation. This grommet cabinet solution reflects CPI's commitment to quality, reliability, and customer‑focused engineering.
