Engineering Details

Details That Simplify Deployment

Removable Side Panels

Side panels detach without tools for fast rack access and multi-cabinet row assembly; side locks optional for tamper protection.

180° Door Opening

Front door turning angle exceeds 180°, so trays and equipment slide out without removing the door in tight aisles.

Cable Entry, Three Sides

Knock-out cable entry holes on top cover, bottom panel and rear panel — supports top, bottom and rear cabling routes.

Zinc-Plated U-Marked Profile

1.8 mm zinc-plated mounting profiles with laser U-markings speed up equipment positioning and repeat installations.

Silent Casters

2-inch casters — 2 swivel and 2 with brakes — allow positioning and locking of fully loaded cabinets on site.

Flat-Pack Logistics

Unassembled packaging saves shipping space and container cost; carton sizes are listed per model in each datasheet.
