Lanberg WF01-6404-23B · 19" Wall Mount Rack Cabinet 4U 600 × 450 mm, Perforated Door, Black
4U · 19"600 × 450 mmPerforated steel door60 kg static load
The Lanberg WF01-6404-23B is a 19-inch wall mount rack cabinet with 4 rack units, 600 mm width and 450 mm depth, closed with a perforated steel front door, for small network installations with a patch panel, a switch and a router or NVR in offices, shops and technical rooms.
The perforated door is the difference to the glass-door sibling (WF01-6404-10B): it lets the switch breathe and keeps the cabinet cooler, while the lockable door still keeps the equipment out of reach. The cabinet has four vertical rails with 379.5 mm mounting depth, takes 60 kg static load, and is delivered as a flat pack for self-assembly, which keeps the carton compact for transport.
Before you order: Mounting depth is 379.5 mm — check the depth of your switch or NVR, including cables at the rear. The cabinet is delivered unassembled.
What's in the Box
- 1 × Lanberg 19" 4U wall cabinet WF01-6404-23B (flat pack: frame, panels, perforated door)
- Front door lock and side panel locks
- Mounting bracket
- Grounding cable
- Mounting hardware set with M6 screws
- User manual
What It Means in Practice
- A 24-port patch panel, a 1U switch, a cable manager and a shelf fill the 4U neatly.
- Perforated door gives passive airflow — for warm PoE switches this matters more than a glass window.
- Lockable door and lockable side panels keep the network out of reach in public areas.
- Two fan positions in the roof let you add active cooling later if the load grows.
What Will Not Work
- Equipment deeper than 379.5 mm (most rack servers, deep NAS units, rack UPS).
- More than 4U of equipment or above 60 kg static load.
- Visible-LED installations where a glass door is preferred — order the -10B glass-door version instead.
- Outdoor, wet or dusty locations — IP20, indoor only.

Frequently Asked Questions
What is the difference between -23B and -10B?
Both are 4U, 600 × 450 mm, black and flat pack. -23B has a perforated steel door; -10B has a tempered glass door.
Does it come with fans?
No. There are two fan positions in the top panel; fan units are sold separately.
Is it hard to assemble?
It is a flat pack with all screws and a manual; expect about 30–45 minutes with basic tools before wall mounting.
Singular Expert Insight · Buyer's Guide
Choose the perforated -23B when the cabinet holds a PoE switch or anything warm; choose glass only when you need to see LEDs without opening. Measure equipment depth against 379.5 mm, and add patch panels, shelves and blanking panels from our
rack accessories.
✓ Buy it if you need a lockable 4U wall cabinet with good passive airflow for a patch panel, switch and router.
✕ Skip it if you need more than 4U, deeper than 379.5 mm mounting depth, or a glass door.
→ Also consider a 6U or 9U 600 × 450 mm wall cabinet if you expect to add a second switch or a UPS shelf.
