Use Case:          Wire protection for racks & enclosures in vertically integrated critical power/climate solutions

Client:                 A major OEM/integrator with critical power, thermal management, racks & enclosures expertise

Solution:            Spring-Fast ® BT Series Grommet Edging — BT1-0025-ER02


  • To ensure the performance of its integrated rack solutions that combined PDUs, UPSs, inverters, switches, multiplexes etc., our client required UL94V-0 compliance as well as abrasion protection for all the cables that had an ingress to, and egress from the units to prevent loss of functionality. They also wanted the form factor to look professional.
  • Other solutions like standard nylon grommets were evaluated but were rejected for several reasons:
    • They did not meet the required flammability UL94 V-0 standard as they are designed and manufactured using non-UL compliant polyethylene thermoplastic materials.
    • The product form did not meet their desired conformance requirements.  Nylon often suffered from coil set and could dis-bond from the edge it was meant to protect.
    • The use of glues or PSA strips to offset coil set could also lead to dis-bonding- even at room temperature – which could threaten the efficacy and performance of their integrated solution.
    • The form factor was poor because gluing the grommet is a non-standard operation which resulted in unprofessional variations and the “look” of their finished product.
