HWMSR20U is a pair of 20U square-hole 19-inch panel rails designed for HWM Series swing-out wall-mount rack cabinets. It is intended for IT, telecom and structured cabling installers who want tool-less, cage-nut style square-hole mounting instead of the tapped 10-32 rails supplied with the cabinet, or who need an additional set of rails inside a 20U HWM enclosure.
The rails are fabricated from mild steel with a painted black (thin) finish as shown on the HWMSR20U drawing. They are sold as a pair and ship with mounting hardware included, so the set can be installed directly into a compatible 20U cabinet body. Rail markings include U-marking to help identify rack unit positions during equipment layout and installation.
Overall rail length is 35.03 in (890 mm), with a 34.50 in (876 mm) 20U mounting height and a 2.23 in (57 mm) rail width. Shipping weight for the pair is 8 lbs (3.63 kg). The rails are referenced in the HWM Series accessory table as the square-hole rail option for 20U cabinets, alongside the HWMTR20U tapped 10-32 rail pair and the HWMRPP20 rear-pan panel.
- Square-hole rail format for cage-nut hardware and 19-inch rack equipment
- U-marking for rack unit reference
- Mounting hardware included with the pair
HWMSR20U is manufactured in Canada, is USMCA compliant, RoHS compliant and REACH compliant, and carries cULus, PCI, Zone 4 and TAA-compliant standards references under UL file E474597.
Ideal For
- Adding square-hole equipment rails to 20U HWM wall-mount cabinets
