APC by Schneider Electric Koldlok Extended Raised Floor Grommet - AR7740

APC by Schneider Electric AR7740 Koldlok Extended Raised Floor Grommet

Overview

The AR7740 is APC by Schneider Electric's Koldlok Extended Raised Floor Grommet — a passive airflow management accessory engineered to seal cable pass-through cutouts in raised-floor data center environments. By closing gaps around cable bundles at floor level, it helps contain cold air beneath the raised floor and directs it where your network infrastructure and equipment actually need it, rather than letting it bleed into hot aisles or bypass equipment entirely.

Available in Black and Silver finishes, the AR7740 fits into standard raised floor tile cutouts. Its extended 610 mm depth dimension accommodates larger or irregularly routed cable bundles that shorter grommets cannot seal effectively — a meaningful distinction in dense cable runs common to enterprise server rooms and colocation deployments. At 204 mm wide and just 26 mm in height profile, it sits flush or near-flush with the tile surface, minimizing trip hazards and maintaining compliance with floor clearance requirements. Package weight of 11.8 kg reflects a robust, commercial-grade build appropriate for high-traffic data center floors.

If you're planning or auditing a data center airflow management deployment, the AR7740 pairs logically with blanking panels and hot/cold aisle containment products from the APC by Schneider Electric infrastructure line to form a complete floor-to-ceiling containment approach. Refer to your data center cooling planning guide for cutout sizing and tile compatibility requirements before ordering.

Key Features

• Extended 610 mm Depth: Handles deep cable bundles and multi-run pass-throughs that standard-length grommets leave partially exposed — critical in backbone cable corridors where airflow leakage is highest.
• 204 mm Width / 26 mm Height Profile: Sized to fit standard raised floor cutouts while maintaining a low surface profile that keeps the floor walkable and meets most facility safety clearance standards.
• Black and Silver Dual-Finish Option: Matches both dark-tile and light-tile raised floor systems without requiring custom orders — useful in mixed-vendor floor environments.
• Commercial-Grade Construction: 11.8 kg package weight signals substantial material density appropriate for data center-class use where grommets must withstand repeated cable pulls and foot traffic near cutout edges.

Integration and Compatibility

The AR7740 is designed for standard raised floor tile cutout installations. Verify your tile cutout dimensions against the 204 x 610 mm footprint before ordering — extended grommets require a matching extended cutout and are not interchangeable with standard square grommets. Compatible with APC data center floor accessories and third-party raised floor systems that use equivalent cutout patterns. Consult your raised floor tile manufacturer's specification for cutout tolerance and tile load ratings when routing heavy cable bundles.

Frequently Asked Questions

Q: What are the installed dimensions of the AR7740?

A: The AR7740 measures 204 mm wide x 610 mm deep x 26 mm in height profile — designed for extended raised floor cutouts that accommodate large or multi-run cable bundles.

Q: What colors does the AR7740 come in?

A: The AR7740 is available in Black and Silver finishes to match a range of raised floor tile systems.

Q: Is the AR7740 suitable for standard raised floor tile cutouts?

A: The AR7740 is an extended-length grommet at 610 mm deep — it requires an extended cutout, not a standard square cutout. Confirm your tile cutout dimensions match before ordering.

Q: Can the AR7740 be used with non-APC raised floor systems?

A: Yes, provided the raised floor tile cutout dimensions match the AR7740's 204 x 610 mm footprint. It is not exclusive to APC floor systems.

Q: What is the package weight of the AR7740?

A: The packaged unit weighs 11.8 kg (approximately 26 lbs), reflecting a substantial commercial-grade build.

James Everett

The AR7740's 610 mm extended depth is the spec that matters most here — standard floor grommets cap out well short of that, and in practice you'll find extended cutouts in backbone cable corridors where you're routing a dozen or more runs simultaneously. If you're sealing those with a short grommet, you're leaving a significant air gap and undermining whatever hot/cold aisle containment you've built above the floor.

Technical Highlights:

• Extended 610 mm Depth: Purpose-built for large-bundle cable pass-throughs; a standard square grommet simply won't cover the cutout geometry in extended raised floor tile configurations.
• 26 mm Installed Height: Low-profile enough to keep the floor surface walkable — in active data center floors with frequent technician access, a tall grommet lip becomes a snag point and a liability.
• Dual Finish (Black/Silver): Minor detail that matters in mixed-vendor floor environments; matching finish to the tile keeps visual inspection of floor integrity straightforward.

Deployment Considerations:

• Confirm your raised floor tile cutout is dimensioned for an extended grommet (204 x 610 mm) before procurement — ordering a standard tile and cutting on-site introduces tolerance risk and can void tile warranties.
• The 11.8 kg packaged weight suggests meaningful material density, but always verify the grommet material's deflection spec against your anticipated cable bundle weight before committing to a dense backbone run across multiple cutouts.

The AR7740 is the right call for enterprise data centers and colocation facilities executing a disciplined raised-floor airflow containment strategy — specifically in backbone cable corridors where extended cutouts are already in place and sealing integrity directly affects cooling efficiency at scale.
