The MIER PRODUCTS bw-109b is a metal enclosure designed to house and protect electronic components, power supplies, and low-voltage electrical equipment in industrial and commercial applications. Built from metal for durability, this box measures 7.25 inches wide, 12 inches high, and 3.5 inches deep, providing adequate interior volume for a range of instrumentation and control hardware. Licensed electricians, HVAC technicians, and industrial maintenance professionals install enclosures like this one wherever protected component housing is required by code or application.
This enclosure is suited for use as a power supply box, a low-voltage electrical housing, or a general-purpose instrument box in both industrial and light commercial settings. Its dimensions make it a practical choice when mounting space is limited but interior clearance for wiring and components is still needed. The bw-109b accommodates a wide variety of installation scenarios where a secure, enclosed housing is required to protect sensitive equipment from physical damage or environmental exposure.
Designed as a general-purpose metal enclosure suitable for industrial instrument, power supply, and low-voltage electrical applications where a 7.25 x 12 x 3.5 inch housing is appropriate.
Installation is typically performed by a licensed electrician or qualified technician in accordance with NEC requirements for enclosure use and wiring methods. De-energize all circuits before mounting or wiring inside the enclosure. Ensure the enclosure is properly grounded per applicable electrical codes before energizing any housed components.
