Panduit GEE189F-C Slotted Grommet Edging

The Panduit GEE189F-C is a 100-foot polyethylene slotted grommet edging designed to protect cables and wiring from abrasion against sharp metal edges in panel walls, knockouts, and enclosure cutouts. Sharp burrs and edges on punched or drilled openings are a common cause of cable jacket damage and eventual conductor exposure in rack installations, electrical panels, and data center infrastructure. This flexible edging snaps into place over irregular and round holes where rigid grommets won't fit, providing a smooth, non-abrasive transition surface. Supplied on a 100-foot reel, the GEE189F-C delivers enough material for multiple enclosures or a full rack deployment without mid-job reordering.

Key Features

Slotted design accommodates irregularly shaped panel openings and round knockouts that rigid grommets cannot fit

Polyethylene construction offers high flexibility for easy installation around complex hole geometries

Fits panel thicknesses from 0.144" to 0.189" (3.66 mm to 4.8 mm) — compatible with standard 14-gauge to 12-gauge sheet metal enclosures

Natural color blends with unfinished enclosures and does not call attention to cable exit points

0.301" (7.7 mm) height and 0.297" (7.6 mm) width cross-section provides substantial edge coverage without obstructing cable bend radius

100-foot (30.48 m) reel packaging allows continuous runs and reduces waste from pre-cut lengths

UL 94 HB flammability rating meets baseline fire safety requirements for low-voltage enclosures

RoHS compliant for installations subject to hazardous substance restrictions

Polyethylene's low coefficient of friction and chemical resistance make it well-suited for long-term cable protection in environments where vibration, thermal cycling, or equipment moves could cause cables to shift against panel edges. The slotted profile allows the edging to be installed after cables are already routed — no need to thread it onto wires during initial pull. Installers can cut the edging to exact lengths on-site, wrap it around the hole perimeter, and press the slot closed over the panel edge. The material's flexibility ensures a snug fit even on holes with slight out-of-round distortion or filed edges. At 0.297" wide, the edging provides coverage beyond the hole's immediate edge, protecting against sharp corners that extend into the knockout zone. The natural color option works in both indoor rack environments and outdoor enclosures where UV stability is less critical than in exposed cable runs.

This edging is commonly deployed in server rack cable pass-throughs, UPS battery cabinet knockouts, CCTV DVR/NVR enclosure penetrations, and electrical sub-panel cutouts where romex or MC cable exits into conduit. The 100-foot reel is well-suited for system integrators outfitting multiple rack rows or data center hot-aisle containment systems with dozens of cable entry points. Field techs stock the reel in service vehicles for retrofit jobs where legacy enclosures have sharp knockouts that were never deburred. The 0.144"–0.189" panel range covers the majority of NEMA-rated enclosures, outdoor CCTV housings, and rackmount chassis used in commercial security and IT infrastructure. For holes larger than the edging's grip range, installers can double-wrap or use the material in combination with Panduit's rigid grommet line.

UL 94 HB flammability rating ensures the edging meets horizontal burn test requirements for non-critical enclosure components — appropriate for low-voltage Class 2 circuits and Power over Ethernet cable runs where the edging is not part of the fire-rated barrier itself. RoHS compliance allows use in EU-regulated installations and municipal projects with lead-free material mandates. The 100-foot reel format reduces per-foot cost compared to pre-cut kits and minimizes packaging waste on large deployments, aligning with integrators' workflow where custom-length cuts are the norm rather than the exception.
