California PROP 65 Warning

For California Residents Only: California Proposition 65 Warning
WARNING: Some products may contain chemicals that are known to the State of California to cause cancer or reproductive harm.

Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law that requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. The warnings are intended to help California consumers make informed decisions about their exposure to these chemicals from the products they use. The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more than 850 chemicals. In August 2016, OEHHA adopted new regulations, effective on August 30, 2018, which change the information required in Proposition 65 warnings.

Additional Information about California Proposition 65

CALIFORNIA WARNING

Description:

Rack Extender Bracket Set — 4U
Rack Hardware Accessory — 4″ Rack Extension

The 4U Rack Extender Bracket Set is designed to extend rack-mounted equipment forward by approximately 4 inches, allowing deeper equipment or recessed rails to mount properly within standard EIA racks and cabinets. These adapters are manufactured in the USA from premium 16-gauge steel and finished in a durable satin-black powder coat for long-term durability in data center and telecom environments.

Why rack extensions are needed
  • Modern servers and UPS equipment often exceed standard rack rail depth.
  • Cabinet rails may be recessed behind front doors or cable managers.
  • Some legacy racks lack sufficient mounting clearance for newer hardware.
Our solution
  • Heavy-duty construction — fabricated from rigid 16-gauge steel.
  • Precision EIA spacing — industry-standard mounting hole pattern.
  • Integrated 10-32 PEM nuts — secure threaded mounting on one side.
  • Durable finish — satin-black powder coating resists wear.
  • Complete hardware kit — includes two common rack screw types.

Each pair of adapters ships boxed and includes mounting hardware for common rack standards:

  • 8 × 12-24 black pan-head dog-point Phillips rack screws
  • 8 × 10-32 black pan-head dog-point Phillips rack screws

U Size Rack Spaces Height (inches) Height (cm)
1U 1 1.75″ 4.45 cm
2U 2 3.50″ 8.89 cm
3U 3 5.25″ 13.34 cm
4U 4 7.00″ 17.78 cm
5U 5 8.75″ 22.23 cm
8U 8 14.00″ 35.56 cm

Maintenance Tip: Multiply the rack unit (U) size by 1.75 to determine the rack height in inches. Example: 5U × 1.75″ = 8.75″ (≈22.23 cm).
