L250 Series Sectional Wall CabinetsBackbox / 14"D Mounting Section / Front Door
Lowell’s UL Listed (Standard 1678) sectional wall cabinet Series L250 features a 14" deep equipment mounting section with full field flexibility, mounting options, and loading strength for swingout access to equipment that is wall mounted. Cabinets include a solid front door or “less door” - LD versions. Choose LD versions when open access or an optional Plexiglas or fully perforated door is specified (order optional door separately).
Field-friendly design features a universal backbox that mounts the 14"D mounting section with right or left hinging. Each mounting section and door, on applicable models, is shipped with hardware mounted for right-hand swing - see diagram on page 3. The backbox is 4.69"D and features 16" mounting centers, top and bottom removable knockout panels, a 10" x 10" opening for mounting over electrical pull boxes, and embossed dimples on the backplane for installation of board-mounted accessories.
The mounting section attaches to the backbox from the inside using two heavy duty, spring-loaded L-pins that are
self-seating and positive locking upon closure for fast and secure installation with no visible hinging or hardware. The stability of Lowell’s L-pin design combined with the section’s fully gusseted corners and triple-formed side-to-bottom and side-to-top wrapped design achieve strength equivalent to 3/16" thick steel for dependable load bearing support.
